Darrick J. Wong e4fd1def30 xfs: create agblock bitmap helper to count the number of set regions 
In the next patch, the rmap btree repair code will need to estimate the
size of the new ondisk rmapbt.  The size is a function of the number of
records that will be written to disk, and the size of the recordset is
the number of observations made while scanning the filesystem plus the
number of OWN_AG records that will be injected into the rmap btree.

OWN_AG rmap records track the free space btrees, the AGFL, and the new
rmap btree itself.  The repair tool uses a bitmap to record the space
used for all four structures, which is why we need a function to count
the number of set regions.

A reviewer requested that this be pulled into a separate patch with its
own justification, so here it is.
