I think the right approach is to create a single blkmirror driver that
also includes blkverify functionality.  The code is basically the same
except blkverify also compares reads - just use a flag to
enable/disable that behavior.

Feel free to rename the blkverify driver to blkmirror if you wish.

By the way, this code does not build against qemu.git/master.  It uses
interfaces which have been dropped.
