zfsd will now try to activate a spare, if one is available, when a resource
dissapears.  Other functionality, such as detaching the spare when the
original device returns, is TBD.

		Created a new Guid class that can have a None value.
		Modified the Vdev class to be able to represent available
		spares, which do not have pool or vdev guids.

	cddl/sbin/zfsd/case_file.cc
		Abstract device replacement into the CaseFile::Replace
		method, which is used by both ActivateSpare and replace by
		physical path.
		Try to active a hotspare whenever a vdev dissappears.
