[XFS] Next step in bhv code cleanup - this is a start on moving quota and dmapi 

into behavior layers, purging several points where these sit slap bang in
the middle of XFS code (esp. read_super).  Also removes numerous #ifdef's
and a bunch of unused #define's from all over the place.  More to come.
