bugzilla-tool land-and-update needs to fix reviewers in ChangeLogs

Right now it just tries to commit and update the bug, but doesn't fix up the ChangeLogs to have a reviewer.

This command is meant for when you're landing your own patches which have been reviewed and are already in your tree (possibly with reviewer-suggested modifications).

It would be easy to grab the reviewer off the patch on the bug (assuming there is only one patch).  We can error-out if there is more than one patch I guess.

Ok.  I've changed "land-and-update" to the shorter "land-diff".

I've also made land-diff know how to build and test before actually committing.

I've also made land-diff's bug_id parameter optional (since sometimes you want to land changes which don't have a bug, but you do want to do want the automated goodness of reviewer setting and one more final build and test before landing.)

A few minor things to fix.  Free to fix up and submit (unless you do larger changes and want another review of it).

Two comments:
1. Indent off by one space ("print line....")
2. Why is there a comma at the end of this line? (Can it be removed?)

It seems like it should update the date in the changelog as well. Could be a fix me for now.

If the comment contains characters like \n, then I think it will mess up the output.  Maybe the log function should be updated to look like this

def log(string):
    print >> sys.stderr, "%s" % string

1.  Fixed
2.  To make print not add a newline when printing:
http://www.python.org/doc/2.4.4/ref/print.html
A "\n" character is written at the end, unless the print statement ends with a comma. This is the only action if the statement contains just the keyword print.

Yeah.  Will add a FIXME for now.

log("foo\nbar") seems to work just fine?

Thanks for the review!

Git got upset with itself.  But this landed as r45351.
