This patch teaches diffcore_rename() to look into
$GIT_DIR/rename-cache and make use of it to recreate diff_filepair.
With proper cache, there should be no available entry for estimation
after exact matching.

This is something I have thought about in the past, good to see that
implemented :)

Rename caching is per commit. I don't think abitrary tree-tree caching
is worth it.

That could be a nice complement to my directory-rename patch.

Has anybody thought about interaction between that caching and pathspec
limited operation?
