Test the setting of the XFS BMBT fields. Runs through the valid
bit values for each field. Also test the value past the last legal
value.
Additionally, ensures setting a core entry (core.gen is used) is
still correct. Test that the hex (#HH) input on a BMBT field and a
core entry are also correct.

+# Test the xfs_db write of the XFS BMBT entries. For each XFS BMBT field,
+# write the value 0, each bit and finally the entry beyond the maximum legal
+# value. Also makes sure a core write and hex input still work.
