tree-wide: do not compile deprecated functions with hard deprecation
When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor
definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h"
header to be empty. As a result, no function declarations are made
available to callers, but the implementations are still available to
link against. This has the problem that function declarations also
aren't visible to the implementations, meaning that the symbol's
visibility will not be set up correctly. As a result, the resulting
library may not expose those deprecated symbols at all on some platforms
and thus cause linking errors.
Fix the issue by conditionally compiling deprecated functions, only.
While it becomes impossible to link against such a library in case one
uses deprecated functions, distributors of libgit2 aren't expected to
pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually
define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real"
hard deprecation still makes sense in the context of CI to test we don't
use deprecated symbols ourselves and in case a dependant uses libgit2 in
a vendored way and knows it won't ever use any of the deprecated symbols
anyway.

diff: make patchid computation work with all types of commits.
Current implementation of patchid is not computing a correct patchid
when given a patch where, for example, a new file is added or removed.
Some more corner cases need to be handled to have same behavior as git
patch-id command.
Add some more tests to cover those corner cases.

Don't use enum for flags
Using an `enum` causes trouble when used with C++ as bitwise operations are not possible w/o casting (e.g., `opts.flags &= ~GIT_BLOB_FILTER_CHECK_FOR_BINARY;` is invalid as there is no `&=` operator for `enum`).

Rename opt init functions to `options_init`
In libgit2 nomenclature, when we need to verb a direct object, we name
a function `git_directobject_verb`. Thus, if we need to init an options
structure named `git_foo_options`, then the name of the function that
does that should be `git_foo_options_init`.
The previous names of `git_foo_init_options` is close - it _sounds_ as
if it's initializing the options of a `foo`, but in fact
`git_foo_options` is its own noun that should be respected.
Deprecate the old names; they'll now call directly to the new ones.

In commit 9be638ecf (git_diff_generated: abstract generated diffs,

forgotten to remove the macros `DIFF_FLAG_IS_SET`, `DIFF_FLAG_ISNT_SET`
and `DIFF_FLAG_SET`, which are now only used in "diff_generated.c".

Make sure to always include "common.h" first
Next to including several files, our "common.h" header also declares
various macros which are then used throughout the project. As such, we
have to make sure to always include this file first in all
implementation files. Otherwise, we might encounter problems or even
silent behavioural differences due to macros or defines not being
defined as they should be. So in fact, our header and implementation
files should make sure to always include "common.h" first.
This commit does so by establishing a common include pattern. Header
files inside of "src" will now always include "common.h" as its first
other file, separated by a newline from all the other includes to make
it stand out as special. There are two cases for the implementation
files. If they do have a matching header file, they will always include
this one first, leading to "common.h" being transitively included as
first file. If they do not have a matching header file, they instead
include "common.h" as first file themselves.
This fixes the outlined problems and will become our standard practice
for header and source files inside of the "src/" from now on.

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.

diff: simplify code for handling empty dirs
When determining diffs between two iterators we may need to
recurse into an unmatched directory for the "new" iterator when
it is either a prefix to the current item of the "old" iterator
or when untracked/ignored changes are requested by the user and
the directory is untracked/ignored.
When advancing into the directory and no files are found, we will
get back `GIT_ENOTFOUND`. If so, we simply skip the directory,
handling resulting unmatched old items in the next iteration. The
other case of `iterator_advance_into` returning either
`GIT_NOERROR` or any other error but `GIT_ENOTFOUND` will be
handled by the caller, which will now either compare the first
directory entry of the "new" iterator in case of `GIT_ENOERROR`
or abort on other cases.
Improve readability of the code to make the above logic more
clear.

iterator: combine fs+workdir iterators more completely
Drop some of the layers of indirection between the workdir and the
filesystem iterators. This makes the code a little bit easier to
follow, and reduces the number of unnecessary allocations a bit as
well. (Prior to this, when we filter entries, we would allocate them,
filter them and then free them; now we do the filtering before
allocation.)
Also, rename `git_iterator_advance_over_with_status` to just
`git_iterator_advance_over`. Mostly because it's a fucking long-ass
function name otherwise.

diff: check pathspec on non-files
When we're not doing pathspec matching, we let the iterator handle
file matching for us. However, we can only trust the iterator to
return *files* that match the pattern, because the iterator must
return directories that are not strictly in the pathlist, but that
are the parents of files that match the pattern, so that diff can
later recurse into them.
Thus, diff must examine non-files explicitly before including them
in the delta list.

to GIT_DELTA_CONFLICTED but then overriding it later with GIT_DELTA_ADDED.

iterator from the diff, though it may be better to have an accessor
instead of moving these structs into the header.

Fixed GIT_DIFF_UPDATE_INDEX not being aware of executable bit changes
In the prior implementation, enabling GIT_DIFF_UPDATE_INDEX would overwrite
entries in the index with the ones generated from scanning the working if the
OID was the same.
Because this OID comparison ignores file modes, this means an file in the
workdir with only an exec bit difference with the one in the index would end
up being overwritten, resulting in the exec bit being loss. There might be
other related bugs but the fix of comparing OIDs and file modes should
address them all.

config: borrow refcounted references
This changes the get_entry() method to return a refcounted version of
the config entry, which you have to free when you're done.
This allows us to avoid freeing the memory in which the entry is stored
on a refresh, which may happen at any time for a live config.
For this reason, get_string() has been forbidden on live configs and a
new function get_string_buf() has been added, which stores the string in
a git_buf which the user then owns.
The functions which parse the string value takea advantage of the
borrowing to parse safely and then release the entry.

iterator: submodules are determined by an index or tree
We cannot know from looking at .gitmodules whether a directory is a
submodule or not. We need the index or tree we are comparing against to
tell us. Otherwise we have to assume the entry in .gitmodules is stale
or otherwise invalid.
Thus we pass the index of the repository into the workdir iterator, even
if we do not want to compare against it. This follows what git does,
which even for `git diff <tree>`, it will consider staged submodules as
such.

Add filter options and ALLOW_UNSAFE
Diff and status do not want core.safecrlf to actually raise an
error regardless of the setting, so this extends the filter API
with an additional options flags parameter and adds a flag so that
filters can be applied with GIT_FILTER_OPT_ALLOW_UNSAFE, indicating
that unsafe filter application should be downgraded from a failure
to a warning.

Improve checks for ignore containment
The diff code was using an "ignored_prefix" directory to track if
a parent directory was ignored that contained untracked files
alongside tracked files. Unfortunately, when negative ignore rules
were used for directories inside ignored parents, the wrong rules
were applied to untracked files inside the negatively ignored
child directories.
This commit moves the logic for ignore containment into the workdir
iterator (which is a better place for it), so the ignored-ness of
a directory is contained in the frame stack during traversal. This
allows a child directory to override with a negative ignore and yet
still restore the ignored state of the parent when we traverse out
of the child.
Along with this, there are some problems with "directory only"
ignore rules on container directories. Given "a/*" and "!a/b/c/"
(where the second rule is a directory rule but the first rule is
just a generic prefix rule), then the directory only constraint
was having "a/b/c/d/file" match the first rule and not the second.
This was fixed by having ignore directory-only rules test a rule
against the prefix of a file with LEADINGDIR enabled.
Lastly, spot checks for ignores using `git_ignore_path_is_ignored`
were tested from the top directory down to the bottom to deal with
the containment problem, but this is wrong. We have to test bottom
to top so that negative subdirectory rules will be checked before
parent ignore rules.
This does change the behavior of some existing tests, but it seems
only to bring us more in line with core Git, so I think those
changes are acceptable.

Add payloads, bitmaps to trace API
This is a proposed adjustment to the trace APIs. This makes the
trace levels into a bitmask so that they can be selectively enabled
and adds a callback-level payload, plus a message-level payload.
This makes it easier for me to a GIT_TRACE_PERF callbacks that
are simply bypassed if the PERF level is not set.

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.

Lay groundwork for updating stat cache in diff
This reorganized the diff OID calculation to make it easier to
correctly update the stat cache during a diff once the flags to
do so are enabled.
This includes marking the path of a git_index_entry as const so
we can make a "fake" git_index_entry with a "const char *" path
and not get warnings. I was a little surprised at how unobtrusive
this change was, but I think it's probably a good thing.

Skip diff oid calc when size definitely changed
When we think the stat cache in the index seems valid and the size
or mode of a file has definitely changed, then don't bother trying
to recalculate the OID of the workdir bits to confirm that it is
modified - just accept that it is modified.
This can result in files that show as modified with no actual diff,
but the behavior actually appears to match Git on the command line.
This also includes a minor optimization to not perform a submodule
lookup on the ".git" directory itself.

Make checkout match diff for untracked/ignored dir
When diff finds an untracked directory, it emulates Git behavior
by looking inside the directory to see if there are any untracked
items inside it. If there are only ignored items inside the dir,
then diff considers it ignored, even if there is no direct ignore
rule for it.
Checkout was not copying this behavior - when it found an untracked
directory, it just treated it as untracked. Unfortunately, when
combined with GIT_CHECKOUT_REMOVE_UNTRACKED, this made is seem that
checkout (and stash, which uses checkout) was removing ignored
items when you had only asked it to remove untracked ones.
This commit moves the logic for advancing past an untracked dir
while scanning for non-ignored items into an iterator helper fn,
and uses that for both diff and checkout.

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.

Decouple index iterator sort from index
This makes the index iterator honor the GIT_ITERATOR_IGNORE_CASE
and GIT_ITERATOR_DONT_IGNORE_CASE flags without modifying the
index data itself. To take advantage of this, I had to export a
number of the internal index entry comparison functions. I also
wrote some new tests to exercise the capability.

Update submodules with parent-tracked content
This updates how libgit2 treats submodule-like directories that
actually have tracked content inside of them. This is a strange
corner case, but it seems that many people have abortive submodule
setups and then just went ahead and added the files into the
parent repository. In this case, we should just treat the
submodule as if it was a normal directory.
Libgit2 will still try to skip over real submodules and contained
repositories that do not have tracked files inside them, but this
adds some new handling for cases where the apparently submodule
data is in conflict with the actual list of tracked files.

Fix skipping content of contained repos
When doing a diff for use in status, we should never show the
content of a git repository contained inside another one. The
logic to do this was looking for a .git directory and so when a
gitlink plain .git file was used, it was failing to exclude the
directory content.

Make submodules externally refcounted
`git_submodule` objects were already refcounted internally in case
the submodule name was different from the path at which it was
stored. This makes that refcounting externally used as well, so
`git_submodule_lookup` and `git_submodule_add_setup` return an
object that requires a `git_submodule_free` when done.
