[Qemu-block] [PATCH v5 0/3] Fix qemu-io return value on failure

[Nir Soffer]

This series fix qemu-io to fail with non zero exit code when failing to open
the file.

Changes since v4:
- Added _unsupported_fmt helper
- Test any format except raw, instead of only raw
- Don't test stderr content, depends on the format
- New test move to 174 since 173 is pending
- Private copyright for new test
- Fix commit message issues

Changes since v3:
- Add cover letter
- Squash the tests fix with the behavior change, so git bisect landing on the
  change in behavior does not hit unnecessarily-broken tests.

Tested by running qemu-io manually and by running tests/check-block.sh.
Note that test 059 has one unrelated test failure.

  qemu-io: Return non-zero exit code on failure
  qemu-iotests: Add _unsupported_fmt helper
  qemu-io: Add failure regression tests
