diff-delta: allow reusing of the reference buffer index
When a reference buffer is used multiple times then its index can be
computed only once and reused multiple times. This patch adds an extra
pointer to a pointer argument (from_index) to diff_delta() for this.
If from_index is NULL then everything is like before.
If from_index is non NULL and *from_index is NULL then the index is
created and its location stored to *from_index. In this case the caller
has the responsibility to free the memory pointed to by *from_index.
If from_index and *from_index are non NULL then the index is reused as
is.
This currently saves about 10% of CPU time to repack the git archive.
