xfs: refactor rtbitmap/summary accessors [v1.2]

Browse source 
Since the rtbitmap and rtsummary accessor functions have proven more
 controversial than the rest of the macro refactoring, split the patchset
 into two to make review easier.
 
 v1.1: various cleanups suggested by hch
 v1.2: rework the accessor functions to reduce the amount of cursor
       tracking required, and create explicit bitmap/summary logging
       functions
 
 With a bit of luck, this should all go splendidly.
