2007-12-11  David Zeuthen  <davidz@redhat.com>

	Rework how volumes, drives and volume monitoring is
	done. Previosly the model was

	 GDrive <1-1> GVolume

	where a GDrive instance represented a mount point and a GVolume
	instance represented a mounted file system. This patch changes it
	the model to

		GDrive <1-N> GVolume <1-1> GMount

	where GMount now serves the purpose of the old GVolume and the new
	GVolume serves the purpose of the old GDrive. In addition the new
	GDrive interface is used to represent a collection of GVolume
	instances (typically partitions) and also contains utility to query
	the state of the physical drive the GDrive object represents (such
	as checking for media, polling the drive, ejecting the media etc.).

	Also implement mounting and unmounting in the Unix volume monitor
	backend. A subquent patch will introduce GDrive support for ejection
	of media.
