[git pull] vfs.git killing ->s_options series

[Al Viro]

	Preparations for fsmount/fsopen stuff (coming next cycle).  Everything
gets moved to explicit ->show_options(), killing ->s_options off + some
cosmetic bits around fs/namespace.c and friends.  Basically, the stuff needed
to work with fsmount series with minimum of conflicts with other work.
	It's not strictly required for this merge window, but it would reduce
the PITA during the coming cycle, so it would be nice to have those bits
and pieces out of the way.
