Hi all,

This series strengthens space allocation record cross referencing by
using our improved xbitmaps to compute the difference between space used
according to the rmap records and the primary metadata, and reports
cross-referencing errors for any discrepancies.

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
