- There don't have to be a lock file.
- Be more userfriendly and allow to specify gbde device name in those forms:
	device
	device.bde
	/dev/device
	/dev/device.bde
- Fix stop routine:
	+ There don't have to be file system mounted on gbde device,
	  so ignore errors from umount(8).
	+ Only detach existing gbde devices.
