c06c79667c diffcore-rename: somewhat optimized.
This changes diffcore-rename to reuse statistics information
gathered during similarity estimation, and updates the hashtable
implementation used to keep track of the statistics to be
denser.  This seems to give better performance.

ba23bbc8ef diffcore-delta: make change counter to byte oriented again.
The textual line oriented change counter was fun but was not
very effective.  It tended to overcount the changes.  This one
changes it to a simple N-letter substring based implementation.

65416758cd diffcore-rename: split out the delta counting code.
This is to rework diffcore break/rename/copy detection code
so that it does not affected when deltifier code gets improved.
