Currently ref lookups require loading the entire packed-refs file into a hashmap in memory. For repos with large numbers of refs this can be painfully slow. This patch replaces the existing lookup code and instead mmap()'s the packed-refs file and performs a binary search to locate the ref entry. Git uses a similiar approach. The old hash table codepath is still used for unsorted packed-refs files. This patch also fixes a minor bug where the "peeled" trait is never parsed correctly from the packed-refs header.
