[v1,0/3] Add post-indexchanged hook

From: Ben Peart <[e-mail]>

Add a post-indexchanged hook that is invoked after the index is written in
do_write_locked_index().

This hook is meant primarily for notification, and cannot affect
the outcome of git commands that trigger the index write.

VFSForGit uses this hook to be notified when a git command has made a
change that could impact the virtual files projected in the working
directory.

I'm submitting this in an effort to further minimize the set of differences
between the VFSForGit fork and git.git in the hope that we can someday
not need a separate fork at all.
