diff: implement function to calculate patch ID
The upstream git project provides the ability to calculate a so-called
patch ID. Quoting from git-patch-id(1):
A "patch ID" is nothing but a sum of SHA-1 of the file diffs
associated with a patch, with whitespace and line numbers ignored."
Patch IDs can be used to identify two patches which are probably the
same thing, e.g. when a patch has been cherry-picked to another branch.
This commit implements a new function `git_diff_patchid`, which gets a
patch and derives an OID from the diff. Note the different terminology
here: a patch in libgit2 are the differences in a single file and a diff
can contain multiple patches for different files. The implementation
matches the upstream implementation and should derive the same OID for
the same diff. In fact, some code has been directly derived from the
upstream implementation.
The upstream implementation has two different modes to calculate patch
IDs, which is the stable and unstable mode. The old way of calculating
the patch IDs was unstable in a sense that a different ordering the
diffs was leading to different results. This oversight was fixed in git
1.9, but as git tries hard to never break existing workflows, the old
and unstable way is still default. The newer and stable way does not
care for ordering of the diff hunks, and in fact it is the mode that
should probably be used today. So right now, we only implement the
stable way of generating the patch ID.

submodule: add an ignore option to status
This lets us specify in the status call which ignore rules we want to
use (optionally falling back to whatever the submodule has in its
configuration).
This removes one of the reasons for having `_set_ignore()` set the value
in-memory. We re-use the `IGNORE_RESET` value for this as it is no
longer relevant but has a similar purpose to `IGNORE_FALLBACK`.
Similarly, we remove `IGNORE_DEFAULT` which does not have use outside of
initializers and move that to fall back to the configuration as well.

or not, in the presence of a conflict. Diff users may have previously
used DELETED to determine this information.

diff/status: introduce conflicts
When diffing against an index, return a new `GIT_DELTA_CONFLICTED`
delta type for items that are conflicted. For a single file path,
only one delta will be produced (despite the fact that there are
multiple entries in the index).
Index iterators now have the (optional) ability to return conflicts
in the index. Prior to this change, they would be omitted, and callers
(like diff) would omit conflicted index entries entirely.

Add diff option to update index stat cache
When diff is scanning the working directory, if it finds a file
where it is not sure if the index entry matches the working dir,
it will recalculate the OID (which is pretty expensive). This
adds a new flag to diff so that if the OID calculation finds that
the file actually has not changed (i.e. just the modified time was
altered or such), then it will refresh the stat cache in the index
so that future calls to diff will not have to check the oid again.

Use git_diff_get_stats in example/diff + refactor
This takes the `--stat` and related example options in the example
diff.c program and converts them to use the `git_diff_get_stats`
API which nicely formats stats for you.
I went to add bar-graph scaling to the stats formatter and noticed
that the `git_diff_stats` structure was holding on to all of the
`git_patch` objects. Unfortunately, each of these objects keeps
the full text of the diff in memory, so this is very expensive. I
ended up modifying `git_diff_stats` to keep just the data that it
needs to keep and allowed it to release the patches. Then, I added
width scaling to the output on top of that.
In making the diff example program match 'git diff' output, I ended
up removing an newline from the sumamry output which I then had to
compensate for in the email formatting to match the expectations.
Lastly, I went through and refactored the tests to use a couple of
helper functions and reduce the overall amount of code there.

Some doc and examples/diff.c changes
I was playing with "git diff-index" and wanted to be able to
emulate that behavior a little more closely with the diff example.
Also, I wanted to play with running `git_diff_tree_to_workdir`
directly even though core Git doesn't exactly have the equivalent,
so I added a command line option for that and tweaked some other
things in the example code.
This changes a minor output thing in that the "raw" print helper
function will no longer add ellipses (...) if the OID is not
actually abbreviated.

Add config read fns with controlled error behavior
This adds `git_config__lookup_entry` which will look up a key in
a config and return either the entry or NULL if the key was not
present. Optionally, it can either suppress all errors or can
return them (although not finding the key is not an error for this
function). Unlike other accessors, this does not normalize the
config key string, so it must only be used when the key is known
to be in normalized form (i.e. all lower-case before the first dot
and after the last dot, with no invalid characters).
This also adds three high-level helper functions to look up config
values with no errors and a fallback value. The three functions
are for string, bool, and int values, and will resort to the
fallback value for any error that arises. They are:
* `git_config__get_string_force`
* `git_config__get_bool_force`
* `git_config__get_int_force`
None of them normalize the config `key` either, so they can only
be used for internal cases where the key is known to be in normal
format.

Add GIT_DIFF_FIND_DELETE_UNMODIFIED flag
When doing copy detection, it is often necessary to include
UNMODIFIED records in the git_diff so they are available as source

diff, often you will not want to have these UNMODIFIED records.
This adds a flag which marks these UNMODIFIED records for deletion
from the diff list so they will be removed after the rename detect
phase is over.

options to be used when those enums need static initialization.

Make diff and status perform soft index reload
This changes `git_index_read` to have two modes - a hard index
reload that always resets the index to match the on-disk data
(which was the old behavior) and a soft index reload that uses
the timestamp / file size information and only replaces the index
data if the file on disk has been modified.
This then updates the git_status code to do a soft reload unless
the new GIT_STATUS_OPT_NO_REFRESH flag is passed in.
This also changes the behavior of the git_diff functions that use
the index so that when an index is not explicitly passed in (i.e.
when the functions call git_repository_index for you), they will
also do a soft reload for you.
This intentionally breaks the file signature of git_index_read
because there has been some confusion about the behavior previously
and it seems like all existing uses of the API should probably be
examined to select the desired behavior.

Create git_diff_line and extend git_diff_hunk
Instead of having functions with so very many parameters to pass
hunk and line data, this takes the existing git_diff_hunk struct
and extends it with more hunk data, plus adds a git_diff_line.
Those structs are used to pass back hunk and line data instead of
the old APIs that took tons of parameters.
Some work that was previously only being done for git_diff_patch
creation (scanning the diff content for exact line counts) is now
done for all callbacks, but the performance difference should not
be noticable.

Diff API cleanup

it should simply show files as "modified".

Add hunk/file headers to git_diff_patch_size
This allows git_diff_patch_size to account for hunk headers and
file headers in the returned size. This required some refactoring
of the code that is used to print file headers so that it could be
invoked by the git_diff_patch_size API.
Also this increases the test coverage and fixes an off-by-one bug
in the size calculation when newline changes happen at the end of
the file.

Add ignore_submodules to diff options
This adds correct support for an equivalent to --ignore-submodules
in diff, where an actual ignore value can be passed to diff to
override the per submodule settings in the configuration.
This required tweaking the constants for ignore values so that
zero would not be used and could represent an unset option to the
diff. This was an opportunity to move the submodule values into
include/git2/types.h and to rename the poorly named DEFAULT values
for ignore and update constants to RESET instead.
Now the GIT_DIFF_IGNORE_SUBMODULES flag is exactly the same as
setting the ignore_submodules option to GIT_SUBMODULE_IGNORE_ALL
(which is actually a minor change from the old behavior in that
submodules will now be treated as UNMODIFIED deltas instead of
being left out totally - if you set GIT_DIFF_INCLUDE_UNMODIFIED).
This includes tests for the various new settings.

Add git_pathspec_match_diff API
This adds an additional pathspec API that will match a pathspec
against a diff object. This is convenient if you want to handle
renames (so you need the whole diff and can't use the pathspec
constraint built into the diff API) but still want to tell if the
diff had any files that matched the pathspec.
When the pathspec is matched against a diff, instead of keeping
a list of filenames that matched, instead the API keeps the list
of git_diff_deltas that matched and they can be retrieved via a
new API git_pathspec_match_list_diff_entry.
There are a couple of other minor API extensions here that were
mostly for the sake of convenience and to reduce dependencies
on knowing the internal data structure between files inside the
library.

Add "as_path" parameters to blob and buffer diffs
This adds parameters to the four functions that allow for blob-to-
blob and blob-to-buffer differencing (either via callbacks or by
making a git_diff_patch object). These parameters let you say
that filename we should pretend the blob has while doing the diff.
If you pass NULL, there should be no change from the existing
behavior, which is to skip using attributes for file type checks
and just look at content. With the parameters, you can plug into
the new diff driver functionality and get binary or non-binary
behavior, plus function context regular expressions, etc.
This commit also fixes things so that the git_diff_delta that is
generated by these functions will actually be populated with the
data that we know about the blobs (or buffers) so you can use it
appropriately. It also fixes a bug in generating patches from
the git_diff_patch objects created via these functions.
Lastly, there is one other behavior change that may matter. If
there is no difference between the two blobs, these functions no
longer generate any diff callbacks / patches unless you have
passed in GIT_DIFF_INCLUDE_UNMODIFIED. This is pretty natural,
but could potentially change the behavior of existing usage.

Add patch from blobs API
This adds two new public APIs: git_diff_patch_from_blobs and
git_diff_patch_from_blob_and_buffer, plus it refactors the code
for git_diff_blobs and git_diff_blob_to_buffer so that they code
is almost entirely shared between these APIs, and adds tests for
the new APIs.

Implement regex pattern diff driver
This implements the loading of regular expression pattern lists
for diff drivers that search for function context in that way.
This also changes the way that diff drivers update options and
interface with xdiff APIs to make them a little more flexible.

Clarify GIT_DIFF_INCLUDE_UNTRACKED_CONTENT option
This improves the docs for GIT_DIFF_INCLUDE_UNTRACKED_CONTENT as
well as the other flags related to UNTRACKED items in diff, plus
it makes that flag now automatically turn on
GIT_DIFF_INCLUDE_UNTRACKED which seems like a reasonable dwim type
of change.

More diff rename tests; better split swap handling
This adds a couple more tests of different rename scenarios.
Also, this fixes a problem with the case where you have two
"split" deltas and the left half of one matches the right half of
the other. That case was already being handled, but in the wrong
order in a way that could result in bad output. Also, if the swap
also happened to put the other two halves into the correct place
(i.e. two files exchanged places with each other), then the second
delta was left with the SPLIT flag set when it really should be
cleared.

Significant rename detection rewrite
This flips rename detection around so instead of creating a
forward mapping from deltas to possible rename targets, instead
it creates a reverse mapping, looking at possible targets and
trying to find a source that they could have been renamed or
copied from. This is important because each output can only
have a single source, but a given source could map to multiple
outputs (in the form of COPIED records).
Additionally, this makes a couple of tweaks to the public rename
detection APIs, mostly renaming a couple of options that control
the behavior to make more sense and to be more like core Git.
I walked through the tests looking at the exact results and
updated the expectations based on what I saw. The new code is
different from the old because it cannot give some nonsense
results (like A was renamed to both B and C) which were part of
the outputs previously.

More git_diff_find_similar improvements
- Add new GIT_DIFF_FIND_EXACT_MATCH_ONLY flag to do similarity
matching without using the similarity metric (i.e. only compare
the SHA).
- Clean up the similarity measurement code to more rigorously
distinguish between files that are not similar and files that
are not comparable (previously, a 0 could either mean that the
files could not be compared or that they were totally different)
- When splitting a MODIFIED file into a DELETE/ADD pair, actually
make a DELETED/UNTRACKED pair if the right side of the diff is
from the working directory. This prevents an odd mix of ADDED
and UNTRACKED files on workdir diffs.

Fix issues with git_diff_find_similar
There are a number of bugs in the rename code that only were
obvious when I started testing it against large old repos with
more complex patterns. (The code to do that testing is not ready
to merge with libgit2, but I do plan to add more thorough tests.)
This contains a significant number of changes and also tweaks the
public API slightly to make emulating core git easier.
Most notably, this separates the GIT_DIFF_FIND_AND_BREAK_REWRITES
flag into FIND_REWRITES (which adds a self-similarity score to
every modified file) and BREAK_REWRITES (which splits the modified
deltas into add/remove pairs in the diff list). When you do a raw
output of core git, rewrites show up as M090 or such, not at A and
D output, so I wanted to be able to emulate that.
Publicly, this also changes the flags to be uint16_t since we
don't need values out of that range.
Internally, this contains significant changes from a number of
small bug fixes (like using the wrong side of the diff to decide
if the object could be found in the ODB vs the workdir) to larger
issues about which files can and should be compared and how the
various edge cases of similarity scores should be treated.
Honestly, I don't think this is the last update that will have to
be made to this code, but I think this moves us closer to correct
behavior and I tried to document the code so it would be easier
to follow..

Add GIT_DIFF_LINE_CONTEXT_EOFNL
This adds a new line origin constant for the special line that
is used when both files end without a newline.
In the course of writing the tests for this, I was having problems
with modifying a file but not having diff notice because it was
the same size and modified less than one second from the start of
the test, so I decided to start working on nanosecond timestamp
support. This commit doesn't contain the nanosecond support, but
it contains the reorganization of maybe_modified and the hooks so
that if the nanosecond data were being read by stat() (or rather
being copied by git_index_entry__init_from_stat), then the nsec
would be taken into account.
This new stuff could probably use some more tests, although there
is some amount of it here.

Update diff handling of untracked directories
When diff encounters an untracked directory, there was a shortcut
that it took which is not compatible with core git. This makes
the default behavior no longer take that shortcut and instead look
inside the untracked directory to see if there are any untracked
files within it. If there are not, then the directory is treated
as an ignore directory instead of an untracked directory. This
has implications for the git_status APIs.

Recursing into ignored dirs for diff and status

and GIT_STATUS_OPT_RECURSE_IGNORED_DIRS along with some tests for
the newly available behaviors. This is not turned on by default
for status, but can be accessed via the options to the extended
version of the command.

diff: allow asking for diffs with no context
Previously, 0 meant default. This is problematic, as asking for 0
context lines is a valid thing to do.
Change GIT_DIFF_OPTIONS_INIT to default to three and stop treating 0
as a magic value. In case no options are provided, make sure the
options in the diff object default to 3.

Add diff rename tests with partial similarity
This adds some new tests that actually exercise the similarity
metric between files to detect renames, copies, and split modified
files that are too heavily modified.
There is still more testing to do - these tests are just partially
covering the cases.
There is also one bug fix in this where a change set with only
MODIFY being broken into ADD/DELETE (due to low self-similarity)
without any additional RENAMED entries would end up not processing
the split requests (because the num_rewrites counter got reset).

Initial integration of similarity metric to diff
This is the initial integration of the similarity metric into
the `git_diff_find_similar()` code path. The existing tests all
pass, but the new functionality isn't currently well tested. The
integration does go through the pluggable metric interface, so it
should be possible to drop in an alternative to the internal
metric that libgit2 implements.
This comes along with a behavior change for an existing interface;
namely, passing two NULLs to git_diff_blobs (or passing NULLs to
git_diff_blob_to_buffer) will now call the file_cb parameter zero
times instead of one time. I know it's strange that that change
is paired with this other change, but it emerged from some
initialization changes that I ended up making.

Replace diff delta binary with flags
Previously the git_diff_delta recorded if the delta was binary.
This replaces that (with no net change in structure size) with
a full set of flags. The flag values that were already in use
for individual git_diff_file objects are reused for the delta
flags, too (along with renaming those flags to make it clear that
they are used more generally).
This (a) makes things somewhat more consistent (because I was
using a -1 value in the "boolean" binary field to indicate unset,
whereas now I can just use the flags that are easier to understand),
and (b) will make it easier for me to add some additional flags to
the delta object in the future, such as marking the results of a
copy/rename detection or other deltas that might want a special
indicator.
While making this change, I officially moved some of the flags that
were internal only into the private diff header.
This also allowed me to remove a gross hack in rename/copy detect
code where I was overwriting the status field with an internal
value.

Refine pluggable similarity API
This plugs in the three basic similarity strategies for handling
whitespace via internal use of the pluggable API. In so doing, I
realized that the use of git_buf in the hashsig API was not needed
and actually just made it harder to use, so I tweaked that API as
well.
Note that the similarity metric is still not hooked up in the
find_similarity code - this is just setting out the function that
will be used.

diff: add a notify callback to `git_diff__from_iterators`
The callback will be called for each file, just before the `git_delta_t` gets inserted into the diff list.
When the callback:
- returns < 0, the diff process will be aborted
- returns > 0, the delta will not be inserted into the diff list, but the diff process continues
- returns 0, the delta is inserted into the diff list, and the diff process continues

Add helper for diff line stats
This adds a `git_diff_patch_line_stats()` API that gets the total
number of adds, deletes, and context lines in a patch. This will
make it a little easier to emulate `git diff --stat` and the like.
Right now, this relies on generating the `git_diff_patch` object,
which is a pretty heavyweight way to get stat information. At
some future point, it would probably be nice to be able to get
this information without allocating the entire `git_diff_patch`,
but that's a much larger project.

Fix diff constructor name order confusion
The diff constructor functions had some confusing names, where the
"old" side of the diff was coming after the "new" side. This
reverses the order in the function name to make it less confusing.
Specifically...
* git_diff_index_to_tree becomes git_diff_tree_to_index
* git_diff_workdir_to_index becomes git_diff_index_to_workdir
* git_diff_workdir_to_tree becomes git_diff_tree_to_workdir
