Staging: remove cowloop driver



The author has found a number of problems with the current version
of this driver in the current kernel, and is reworking it to get
things working again.  Because of that, it would be better to remove
the driver now and add it back in a future kernel release.

		---help---
		Cowloop is a "copy-on-write" pseudo block driver. It can be
		stacked on top of a "real" block driver, and catches all write
		operations on their way from the file systems layer above to
		the real driver below, effectively shielding the lower driver
		from those write accesses. The requests are then diverted to
		an ordinary file, located somewhere else (configurable). Later
		read requests are checked to see whether they can be serviced
		by the "real" block driver below, or must be pulled in from
		the diverted location. More information and userspace tools to
		use the driver are on the project's website
		http://www.ATComputing.nl/cowloop/
