xfs: refactor rt extent unit conversions [v1.1]

Browse source 
This series replaces all the open-coded integer division and
 multiplication conversions between rt blocks and rt extents with calls
 to static inline helpers.  Having cleaned all that up, the helpers are
 augmented to skip the expensive operations in favor of bit shifts and
 masking if the rt extent size is a power of two.
 
 v1.1: various cleanups suggested by hch
 
 With a bit of luck, this should all go splendidly.
