What's in git.git

[Junio C Hamano <junkio@cox.net>]

GIT 1.3.0-rc1 is pushed out and will be mirrored out soon.

All of the things that were not in the "master" branch were
either cooked long enough in "next" without causing problems
(e.g. insanely fast rename detector or true built-in diff) or
isolated in a specific subsystem (e.g. tar-tree and svnimport).

So I am clearing the deck to prepare for a 1.3.0.  Remaining
wrinkles, if any, will be ironed out in the "master" branch.
