layouts: refactor out svn path to mercurial branch logic
This pulls the logic for mapping from svn path to mercurial branch
name out of svnmeta.py and into the new layouts library. It also sets
up the structure for that library. This diff does not modify any call
to svnmeta.localname, rather leaving it in place as a simple proxy to
the new layout object.
