qemu-io has no modes to just dumb the output without additional
information / statistics or for the write case just take user input
instead of a pattern.  I actually tried to add raw arguments to
qemu-io, which still worked ou ok for reads but started to get
fairly ugly for the write.

What I use in production right now is a trivial qemu-cat tool that
just does the raw reads and writes, but I think adding it as a new
sub command to qemu-img instead of another tool seems a bit cleaner.

If you and Kevin or Anthony disagree and want the qemu-cat tool I can
submit a patch for that instead.
