[PATCH v2 05/15] builtin/fetch-pack: remove constants with parse_oid_hex

From: brian m. carlson <sandals@crustytoothpaste.net>
Date: Oct 15, 2018, 00:01 UTC
Message-ID: <20181015000202.951965-6-sandals@crustytoothpaste.net>
In-Reply-To: <20181015000202.951965-1-sandals@crustytoothpaste.net>

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.
