	Provide eject() on both GMount and GVolume and utility functions
	to guess whether a GUnixMountPoint or GUnixMountEntry should be
	ejected. 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.
