What's in git.git (stable)

[Junio C Hamano <gitster@pobox.com>]

With a few late topics came quite a few regression fixes to make us ready
for -rc1.

 * gitk, git-gui and git-p4 have been updated.

 * "git gc --auto" annoyance is hopefully reduced away.

 * Breakage in automated tag following by git-fetch rewritten in C has
   hopefully been fixed.

 * Quite a few portability improvements from Solaris porting efforts.

 * "git remote show" does not talk about symrefs anymore.

 * "git help" updates to plug in more backends.

 * "git submodule summary" to show symmetric differences between commits
   in submodules.
