What's in git.git

I've merged up a lot for people to have fun over the weekend ;-).

The most notable core-ish change is that rev-list split and new git-log implementation by Linus. I've been using this myself for a while without problems, but there might still be some corner cases that I (and Linus perhaps) do not exercise where git-log command behaves slightly differently. rev-list is not supposed to have *any* regression other than removal of --merge-order. Please report regressions.

A new killer application is git-cvsserver. It now talks pserver protocol for anonymous CVS access. Helping Martin to audit the code for any issues, security or otherwise, is greatly appreciated.

Fredrik's git-blame still has -Wdeclaration-after-statement issues, but deserves to be beaten harder alongside Ryan's git-annotate for two reasons. It should be a good example program to use the new revision traversal infrastructure, and it is always good to have competing two implementations ;-).
