diffcore_count_changes: pass diffcore_filespec

We may want to use richer information on the data we are dealing
with in this function, so instead of passing a buffer address
and length, just pass the diffcore_filespec structure.  Existing
callers always call this function with parameters taken from a
filespec anyway, so there is no functionality changes.
