Last stop in the delta-encoding API widening for >4 GiB blobs on
Windows: with create_delta_index() done in the prior commit and
create_delta()/diff_delta() finished here, every byte count that
crosses delta.h is now size_t. The struct fields they store into
have been size_t since the diff-delta struct widening.
The API change must move with all callers in the same commit (the
build only passes when every &delta_size matches the new size_t*).
Caller updates are kept minimal:
* builtin/pack-objects.c get_delta() and try_delta(): widen only
the local delta_size variable; the surrounding unsigned-long
locals and their cast_size_t_to_ulong() shims are out of scope
here and will be cleaned up in their own commits.
* builtin/fast-import.c, diff.c, t/helper/test-pack-deltas.c:
keep the local unsigned-long delta size (each feeds a still-
unsigned-long downstream consumer: zlib's avail_in,
deflate_it(), the test helper's own do_compress()), and bridge
via a temporary size_t plus cast_size_t_to_ulong(). The new
casts are paid back in later topics that widen those consumers.
* t/helper/test-delta.c: widen the local outright (no downstream
consumer beyond the test's own out_size, which is already
size_t).
