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 git_diff_patch_size() API
This adds a new API to get the size in bytes of the diffs in a
git_diff_patch object.

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.

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.

Fix line numbering for patches with eofnl
When a patch contained an eofnl change (i.e. the last line either
gained or lost a newline), the oldno and newno line number values
for the lines in the last hunk of the patch were not useful. This
makes them behave in a more expected manner.

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.

Improve diff config options handling
This makes diff use the cvar cache for config options where
possible, and also adds support for a number of other config
options to diff including "diff.context", "diff.ignoreSubmodules",
"diff.noprefix", "diff.mnemonicprefix", and "core.abbrev".
To make this natural, this involved a rearrangement of the code
that allocates the diff object vs. the code that initializes it
based on the combination of options passed in by the user and
read from the config.
This commit includes tests for most of these new options as well.

Fix a few leaks
`git_diff_get_patch()` would unconditionally load the patch object and
then simply leak it if the user hadn't requested it. Short-circuit
loading the object if the user doesn't want it.
The rest of the plugs are simply calling the free functions of objects
allocated during the tests.

Allow empty config object and use it
This removes assertions that prevent us from having an empty
git_config object and then updates some tests that were
dependent on global config state to use an empty config before
running anything.

Fix tests for find_similar and related
This fixes both a test that I broke in diff::patch where I was
relying on the current state of the working directory for the
renames test data and fixes an unstable test in diff::rename
where the environment setting for the "diff.renames" config was
being allowed to influence the test results.

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 patch line number calculation
This was just wrong. Added a test that verifying patch line
numbers even for hunks further into a file and then fixed the
algorithm. I needed to add a little extra state into the patch
so that I could track old and new file numbers independently,
but it should be okay.

Update diff callback param order
This makes the diff functions that take callbacks both take
the payload parameter after the callback function pointers and
pass the payload as the last argument to the callback function
instead of the first. This should make them consistent with
other callbacks across the API.

Add const to all shared pointers in diff API
There are a lot of places where the diff API gives the user access
to internal data structures and many of these were being exposed
through non-const pointers. This replaces them all with const
pointers for any object that the user can access but is still
owned internally to the git_diff_list or git_diff_patch objects.
This will probably break some bindings... Sorry!
