git-codereview: new sync-branch and related fixes

This CL adds a new command, "git codereview sync-branch",
which does the appropriate git merge for the current branch.

This CL also fixes a bug in "git codereview branchpoint",
and therefore also commands like "git codereview pending",
which was getting the branchpoint wrong for merges,
with the effect that a merge showed too many pending CLs.

This CL also fixes a bug in "git codereview change", which was
formerly willing to run "git checkout" with a pending merge,
which had the effect of flattening the merge mysteriously.
Now it detects the merge and refuses to run.

All of this should make merges easier and less error-prone
as we use dev branches more often.

With the earlier CL in this stack that allows working directly
on local branches, this is now a great way to run a merge
updating dev.regabi:

	git change dev.regabi
	git sync-branch

(with appropriate aliases to avoid typing "codereview").

Fixes golang/go#26201.
