[PATCH 04/14] builtin/fetch-pack: remove constants with parse_oid_hex

[brian m. carlson]

Instead of using GIT_SHA1_HEXSZ, use parse_oid_hex to compute a pointer
and use that in comparisons.  This is both simpler to read and works
independent of the hash length.  Update references to SHA-1 in the same
function to refer to object IDs instead.
