Log message:
	Add a new "flags" parameter to lm_mount() of the lock module interface.
	When the flag LM_MFLAG_SPECTATOR flag is passed in to the lock module,
	GFS is asking to join the filesystem's lockspace, but it doesn't want to
	modify the filesystem.  The lock module shouldn't assign a journal to the
	FS mount.  It shouldn't send recovery callbacks to the FS mount.  If the
	node dies or withdraws, all locks can be wipped immediately.
	
	If the lock module doesn't implement the flag, GFS will work as expected
	except that the mount will reserve a journal it will never use.
	
	Add and implement a "spectator" mount option to GFS to take advantage
	of the spectator mount flag.  When the mount option is used, the FS
	looks just like a RO filesystem.  The difference is you can have lots and
	lots of them.
