Make the verify_pack_callback take a pointer to struct object_id.
Change the pack checksum to use GIT_MAX_RAWSZ, even though it is not
strictly an object ID. Doing so ensures resilience against future hash
size changes, and allows us to remove hard-coded assumptions about how
big the buffer needs to be.
Also, use a union to convert the pointer from nth_packed_object_sha1 to
to a pointer to struct object_id. This behavior is compatible with GCC
and clang and explicitly sanctioned by C11. The alternatives are to
just perform a cast, which would run afoul of strict aliasing rules, but
should just work, and changing the pointer into an instance of struct
object_id and copying the value. The latter operation could seriously
bloat memory usage on fsck, which already uses a lot of memory on some
repositories.

Convert lookup_commit, lookup_commit_or_die,

Introduce a temporary in parse_object buffer in order to convert this
function. This is required since in order to convert parse_object and
parse_object_buffer, lookup_commit_reference_gently and
lookup_commit_or_die would need to be converted. Not introducing a
temporary would therefore require that lookup_commit_or_die take a
struct object_id *, but lookup_commit would take unsigned char *,
leaving a confusing and hard-to-use interface.
