diff: treat binary patches with no data special
When creating and printing diffs, deal with binary deltas that have
binary data specially, versus diffs that have a binary file but lack the
actual binary data.

diff_print: change test for skipping binary printing
Instead of skipping printing a binary diff when there is no data, skip
printing when we have a status of `UNMODIFIED`. This is more in-line
with our internal data model and allows us to expand the notion of
binary data.
In the future, there may have no data because the files were unmodified
(there was no data to produce) or it may have no data because there was
no data given to us in a patch. We want to treat these cases
separately.

patch: show copy information for identical copies
When showing copy information because we are duplicating contents,
for example, when performing a `diff --find-copies-harder -M100 -B100`,
then show copy from/to lines in a patch, and do not show context.
Ensure that we can also parse such patches.

diff_print: assert patch is non-NULL
When invoking `diff_print_info_init_frompatch` it is obvious that
the patch should be non-NULL. We explicitly check if the variable
is set and continue afterwards, happily dereferencing the
potential NULL-pointer.
Fix this by instead asserting that patch is set. This also
silences Coverity.

Fix binary diffs
git expects an empty line after the binary data:

The last literal block of the generated patches were not containing the required empty line. Example:

index 3f1b3f9098131cfecea4a50ff8afab349ea66d22..86e5c1008b5ce635d3e3fffa4434c5eccd8f00b6 100644

GIT binary patch

git apply of that diff results in:

Introduce a new binary diff callback to provide the actual binary

(instead of directly from the ODB) to support binary diffs including
the workdir, not just things coming out of the ODB.

Be more careful with user-supplied buffers
This adds in missing calls to `git_buf_sanitize` and fixes a
number of places where `git_buf` APIs could inadvertently write
NUL terminator bytes into invalid buffers. This also changes the
behavior of `git_buf_sanitize` to NUL terminate a buffer if it can
and of `git_buf_shorten` to do nothing if it can.
Adds tests of filtering code with zeroed (i.e. unsanitized) buffer
which was previously triggering a segfault.

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.

Drop git_patch_to_str
It's hard or even impossible to correctly free the string buffer
allocated by git_patch_to_str in some circumstances. Drop the function
so people have to use git_patch_to_buf instead - git_buf has a dedicated
destructor.

Expose patch serialization to git_buf
Returning library-allocated strings from libgit2 works fine on Linux,
but may cause problems on Windows because there is no one C Runtime that
everything links against. With libgit2 not exposing its own allocator,
freeing the string is a gamble.
git_patch_to_str already serializes to a buffer, then returns the
underlying memory. Expose the functionality directly, so callers can use
the git_buf_free function to free the memory later.

Remove converting user error to GIT_EUSER
This changes the behavior of callbacks so that the callback error
code is not converted into GIT_EUSER and instead we propagate the
return value through to the caller. Instead of using the
giterr_capture and giterr_restore functions, we now rely on all
functions to pass back the return value from a callback.
To avoid having a return value with no error message, the user
can call the public giterr_set_str or some such function to set
an error message. There is a new helper 'giterr_set_callback'
that functions can invoke after making a callback which ensures
that some error message was set in case the callback did not set
one.
In places where the sign of the callback return value is
meaningful (e.g. positive to skip, negative to abort), only the
negative values are returned back to the caller, obviously, since
the other values allow for continuing the loop.
The hardest parts of this were in the checkout code where positive
return values were overloaded as meaningful values for checkout.
I fixed this by adding an output parameter to many of the internal
checkout functions and removing the overload. This added some
code, but it is probably a better implementation.
There is some funkiness in the network code where user provided
callbacks could be returning a positive or a negative value and
we want to rely on that to cancel the loop. There are still a
couple places where an user error might get turned into GIT_EUSER
there, I think, though none exercised by the tests.

Improve GIT_EUSER handling
This adds giterr_user_cancel to return GIT_EUSER and clear any
error message that is sitting around. As a result of using that
in places, we need to be more thorough with capturing errors that
happen inside a callback when used internally. To help with that,
this also adds giterr_capture and giterr_restore so that when we
internally use a foreach-type function that clears errors and
converts them to GIT_EUSER, it is easier to restore not just the
return value, but the actual error message text.

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.

Add hunk/file headers to git_diff_patch_size

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 "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.

More tests and bug fixes for status with rename
This changes the behavior of the status RENAMED flags so that they
will be combined with the MODIFIED flags if appropriate. If a file
is modified in the index and also renamed, then the status code
will have both the GIT_STATUS_INDEX_MODIFIED and INDEX_RENAMED bits
set. If it is renamed but the OID has not changed, then just the
GIT_STATUS_INDEX_RENAMED bit will be set. Similarly, the flags
GIT_STATUS_WT_MODIFIED and GIT_STATUS_WT_RENAMED can both be set
independently of one another.
This fixes a serious bug where the check for unmodified files that
was done at data load time could end up erasing the RENAMED state
of a file that was renamed with no changes.
Lastly, this contains a bunch of new tests for status with renames,
including tests where the only rename changes are case changes.
The expected results of these tests have to vary by whether the
platform uses a case sensitive filesystem or not, so the expected
data covers those platform differences separately.

Reorganize diff and add basic diff driver
This is a significant reorganization of the diff code to break it
into a set of more clearly distinct files and to document the new
organization. Hopefully this will make the diff code easier to
understand and to extend.
This adds a new `git_diff_driver` object that looks of diff driver
information from the attributes and the config so that things like
function content in diff headers can be provided. The full driver
spec is not implemented in the commit - this is focused on the
reorganization of the code and putting the driver hooks in place.
This also removes a few #includes from src/repository.h that were
overbroad, but as a result required extra #includes in a variety
of places since including src/repository.h no longer results in
pulling in the whole world.
