xfs: introduce bitmap type for AG blocks

Browse source

Create a typechecked bitmap for extents within an AG.  Online repair
uses bitmaps to store various different types of numbers, so let's make
it obvious when we're storing xfs_agblock_t (and later xfs_fsblock_t)
versus anything else.

In subsequent patches, we're going to use agblock bitmaps to enhance the
rmapbt checker to look for discrepancies between the rmapbt records and
AG metadata block usage.
