[PATCH] Detect renames in diff family.
This rips out the rename detection engine from diff-helper and moves it to the diff core, and updates the internal calling convention used by diff-tree family into the diff core. In order to give the same option name to diff-tree family as well as to diff-helper, I've changed the earlier diff-helper '-r' option to '-M' (stands for Move; sorry but the natural abbreviation 'r' for 'rename' is already taken for 'recursive'). Although I did a fair amount of test with the git-diff-tree with existing rename commits in the core GIT repository, this should still be considered beta (preview) release. This patch depends on the diff-delta infrastructure just committed. This implements almost everything I wanted to see in this series of patch, except a few minor cleanups in the calling convention into diff core, but that will be a separate cleanup patch.
