Consolidate btree block handling for xfs_db

Currently xfs_db has five different implementations for poking at btree
blocks, even duplicating code for btree blocks with entirely identical
layout (bmapbta vs bmapbtd and bno vs cnt).  Merge all these into
a single implementation that uses a table of btree characteristics keyed
of their magic number.

There's probably a way to further consolidate the magic arrays for the
different types, but I don't quite understand xfs_db's table driven
command parser for that.
