Add bdiff.blocks / minor performance tweaks
This refactors bdiff.bdiff so that we can get a list of matching
blocks of line numbers for use by annotate/unidiff.
Minor performance tweaks:
- - add a field for equivalence so we can keep h around a bit longer for cmp
- - mix len into the hash to reduce collisions
- - move an operation into the slow path in longest_match
