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".

tests: apply: fix reference to deprecated `git_buf_free`
Since commit 56ffdfc61 (buffer: deprecate `git_buf_free` in favor of
`git_buf_dispose`, 2018-02-08), the function `git_buf_free` is
deprecated and shall not be used anymore. As part of the new apply
framework that has been cooking for quite some time some new references
have been introduced to that deprecated function. Replace them with
calls to `git_buf_dispose`.

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.

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.

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.)

Move the location option to an argument, out of the options structure.
This allows the options structure to be re-used for functions that don't
need to know the location, since it's implicit in their functionality.
For example, `git_apply_tree` should not take a location, but is
expected to take all the other options.

apply: validate workdir contents match index for BOTH
When applying to both the index and the working directory, ensure that
the index contents match the working directory. This mirrors the
requirement in `git apply --index`.
This also means that - along with the prior commit that uses the working
directory contents as the checkout baseline - we no longer expect
conflicts during checkout. So remove the special-case error handling
for checkout conflicts. (Any checkout conflict now would be because the
file was actually modified between the start of patch application and
the checkout.)

changes are also kept.
