H A D223636192c4 Fri Jan 11 19:47:20 GMT 2019 Eric Blake <eblake@redhat.com> qemu-nbd: Add --bitmap=NAME option

Having to fire up qemu, then use QMP commands for nbd-server-start
and nbd-server-add, just to expose a persistent dirty bitmap, is
rather tedious. Make it possible to expose a dirty bitmap using
just qemu-nbd (of course, for now this only works when qemu-nbd is
visiting a BDS formatted as qcow2).

Of course, any good feature also needs unit testing, so expand
iotest 223 to cover it.
