Make our overflow check look more like gcc/clang's
Make our overflow checking look more like gcc and clang's, so that
we can substitute it out with the compiler instrinsics on platforms
that support it. This means dropping the ability to pass `NULL` as
an out parameter.
As a result, the macros also get updated to reflect this as well.

git__*allocarray: safer realloc and malloc
Introduce git__reallocarray that checks the product of the number
of elements and element size for overflow before allocation. Also
introduce git__mallocarray that behaves like calloc, but without the
`c`. (It does not zero memory, for those truly worried about every
cycle.)

Use `size_t` to hold size of arrays
Use `size_t` to hold the size of arrays to ease overflow checking,
lest we check for overflow of a `size_t` then promptly truncate
by packing the length into a smaller type.

allocations: test for overflow of requested size
Introduce some helper macros to test integer overflow from arithmetic
and set error message appropriately.

array: mark the array to grow as volatile
This works around strict aliasing rules letting some versions of
GCC (particularly on RHEL 6) thinking that they can skip updating the
size of the array when calculating the next element's offset.

Bug fixes and cleanups
This contains a few bug fixes and some header and API cleanups.
The main API change is that filters should now use GIT_PASSTHROUGH
to indicate that they wish to skip processing a file instead of
GIT_ENOTFOUND.
The bug fixes include a possible out-of-range buffer access in
the ident filter, a filter ordering problem I introduced into the
custom filter tests on Windows, and a filter buf NUL termination
issue that was coming up on Linux.

revwalk: make mark_unintersting use a loop
Using a recursive function can blow the stack when dealing with long
histories. Use a loop instead to limit the call chain depth.
This fixes #1223.

Add git_pathspec_match_diff API
This adds an additional pathspec API that will match a pathspec
against a diff object. This is convenient if you want to handle
renames (so you need the whole diff and can't use the pathspec
constraint built into the diff API) but still want to tell if the
diff had any files that matched the pathspec.
When the pathspec is matched against a diff, instead of keeping
a list of filenames that matched, instead the API keeps the list
of git_diff_deltas that matched and they can be retrieved via a
new API git_pathspec_match_list_diff_entry.
There are a couple of other minor API extensions here that were
mostly for the sake of convenience and to reduce dependencies
on knowing the internal data structure between files inside the
library.

Convert commit->parent_ids to git_array_t
This converts the array of parent SHAs from a git_vector where
each SHA has to be separately allocated to a git_array_t where
all the SHAs can be kept in one block. Since the two collections
have almost identical APIs, there isn't much involved in making
the change. I did add an API to git_array_t so that it could be
allocated at a precise initial size.

Improvements to git_array
This changes the size data to uint32_t, fixes the array growth
logic to use a simple 1.5x multiplier, and uses a generic inline
function for growing the array to make the git_array_alloc API
feel more natural (i.e. it returns a pointer to the new item).
