layouts: pull out code for detecting layout from subversion
This is the start of an effort to refactor the code for how we handle
subversion layoout to mercurial layout mapping. Specifically, it
pulls out the logic for guessing what layout to use based on the
contents of subversion. It also sets up a bit of the structure for
the new library.
