apply: add GIT_APPLY_CHECK
This adds an option which will check if a diff is applicable without
actually applying it; equivalent to git apply --check.

tests: move apply_helpers functions into own compilation unit
Currently, the "apply_helper" functions used for testing the apply logic are all
statically defined in the "apply_helpers.h" header file. This may lead to
warnings from the compiler in case where this header file is included, but not
all functions it brings along are used in the compilation unit where it has been
included into.
Fix these potential warnings by moving the implementation into its own
compilation unit "apply_helpers.c".

Ensure that we can add a file back after it's been removed. Update the
renamed/deleted validation in application to not apply to deltas that
are adding files to support this.

apply: test modifying a file after renaming it
Ensure that we cannot modify a file after it's been renamed out of the
way. If multiple deltas exist for a single path, ensure that we do not
attempt to modify a file after it's been renamed out of the way.
To support this, we must track the paths that have been removed or
renamed; add to a string map when we remove a path and remove from the
string map if we recreate a path. Validate that we are not applying to
a path that is in this map, unless the delta is a rename, since git
supports renaming one file to two different places in two different
deltas.
Further, test that we cannot apply a modification delta to a path that
will be created in the future by a rename (a path that does not yet
exist.)

apply: test renaming a file after modifying it
Multiple deltas can exist in a diff, and can be applied in-order.
If there exists a delta that modifies a file followed by a delta that
renames that file, then both will be captured. The modification delta
will be applied and the resulting file will be staged with the original
filename. The rename delta will be independently applied - to the
original file (not the modified file from the original delta) and staged
independently.

apply: test that we can't rename a file after modifying it
Multiple deltas can exist in a diff, and can be applied in-order.
However if there exists a delta that renames a file, it must be first,
so that other deltas can reference the resulting target file.
git enforces this (`error: already exists in index`), so ensure that we
do, too.

apply: handle multiple deltas to the same file
git allows a patch file to contain multiple deltas to the same file:
although it does not produce files in this format itself, this could
be the result of concatenating two different patch files that affected
the same file.
git apply behaves by applying this next delta to the existing postimage
of the file. We should do the same. If we have previously seen a file,
and produced a postimage for it, we will load that postimage and apply
the current delta to that. If we have not, get the file from the
preimage.

apply: test rename 1 to 2
Test that a patch can contain two deltas that appear to rename an
initial source file to two different destination paths. Git creates
both target files with the initial source contents; ensure that we do,
too.

apply: test rename 2 to 1
Test that we can apply a patch that renames two different files to the
same target filename. Git itself handles this scenario in a last-write
wins, such that the rename listed last is the one persisted in the
target. Ensure that we do the same.

apply: test rename A -> B -> C scenarios
Test that we can rename some file from B->C and then rename some other
file from A->B. Do this with both exact rename patches (eg `rename from
...` / `rename to ...`) and patches that remove the files and replace
them entirely.

apply: handle exact renames
Deltas containing exact renames are special; they simple indicate that a
file was renamed without providing additional metadata (like the
filemode). Teach the reader to provide the file mode and use the
preimage's filemode in the case that the delta does not provide one.)
