Remove the BPCSHIFT and NB* based macros from XFS.
The BPCSHIFT based macros, btoc*, ctob*, offtoc* and ctooff
are either not used or don't need to be used.
The NDPP, NDPP, NBBY macros don't need to be used but instead
are replaced directly by PAGE_SIZE and PAGE_CACHE_SIZE
where appropriate.
Initial patch and motivation from Nicolas Kaiser.
Bunch of reviews from Dave Chinner and final from Lachlan.
