Introduce the concept of UUID's and wire it into GVolume and GMount and provide API on GVolumeMonitor to find such instances. Also handle the case where an external GNativeVolumeMonitor fails to initialize. Lock around the _g_get_mount_for_mount_path() function such that volume monitor implementations won't have to do locking themselves. svn path=/trunk/; revision=6140
