[PATCH v2 0/5] qemu-iotests: quality of life improvements

[Paolo Bonzini]

This series adds a few usability improvements to qemu-iotests, in
particular:

- arguments can be passed to Python unittests scripts, for example
  to run only a subset of the test cases (patches 1-2)

- it is possible to do "./check -- ../../../tests/qemu-iotests/055 args..."
  and specify arbitrary arguments to be passed to a single test script.
  This allows to take advantage of the previous feature and ease debugging
  of Python tests.

Paolo
