  Add git_oid_strcmp and use it for git_oid_streq Add a new git_oid_strcmp that compares a string OID with a hex oid for sort order, and then reimplement git_oid_streq using it. This actually should speed up git_oid_streq because it only reads as far into the string as it needs to, whereas previously it would convert the whole string into an OID and then use git_oid_cmp.
