[PATCHSET,v1.0,0/8] xfs_db: debug realtime geometry

Hi all,

Before we start modernizing the realtime device, let's first make a few
improvements to the XFS debugger to make our lives easier.  First up is
making it so that users can point the debugger at the block device
containing the realtime section, and augmenting the io cursor code to be
able to read blocks from the rt device.  Next, we add a new geometry
conversion command (rtconvert) to make it easier to go back and forth
between rt blocks, rt extents, and the corresponding locations within
the rt bitmap and summary files.

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.
