Change how NoConfigEnvironment does masters.

Now rather than specifying the master repository directory, we specify
the master repository name (if there's no layout.conf) and a number of
extra repository directories.

Clients now use --extra-repository-dir (possibly multiple times) and
--master-repository-name (if it can't be determined automatically)
instead of --master-repository-dir.

Fixes: ticket:635.
