convert mqueue

Browse Source 
All modifications via normal VFS codepaths; just take care of making
persistent in in mqueue_create_attr() and discardable in mqueue_unlink()
and it doesn't need kill_litter_super() at all.

mqueue_unlink() side is best handled by having it call simple_unlink()
rather than duplicating its guts...
