[PATCH 7/7] Use a separate directory for patches under each branch subdir

Currently you can't specify a patch name that matches the name of one of
the stgit special files under .git/patches/<branch-name>.  Let's use a
new subdirectory under .git/patches/<branch-name> to contain just the
patch directories to remove this limitation.
