[PATCH v3 for-4.2 0/4] tests: More iotest 223 improvements

[Eric Blake]

Since v2:
- rebase to SOCK_DIR changes
- new patch 2 to avoid TCP port 10810 contention [Max]
- add imgfmt filtering [Max]

As this is limited to iotests, I think it is fair game for -rc2.

Eric Blake (4):
  iotests: Fix 173
  iotests: Switch nbd tests to use Unix rather than TCP
  iotests: Include QMP input in .out files
  tests: More iotest 223 improvements
