[PATCH 0/1] xdiff: share xdiff between git and libgit2

Hello from libgit2, where we borrowed your xdiff a few years ago and have watched as we both hacked on it independently. (For us, mostly it was around tightening some things up around warnings and signed/unsigned mismatches.) However, we'd love to share a common xdiff implementation, and we're happy if git is the home for that.

The next patch adds an indirection point, `git-xdiff.h`, that contains the git-specific functionality in xdiff. This keeps the core of xdiff to standard functions. Other xdiff users, like libgit2, can specify their own compatibility functions in this header file.

I hope that this allows us to make progress on a common xdiff; we'd love to go back to building it without warnings, but we'd like to not do that in isolation.

Cheers- -ed
