[PATCH v4 0/5] qemu-iotests: quality of life improvements

[Paolo Bonzini]

This series adds a few usability improvements to qemu-iotests, mostly
for Python unittest-based tests.  In particular:

- the output of the unittest framework is not buffered, which makes it
  easier to follow the "-d" output of the tests

- 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 is especially useful together with the previous feature and eases
  the debugging of Python tests.

v3->v4: output of Python tests regenerated when needed

Paolo Bonzini (5):
  qemu-iotests: do not buffer the test output
  qemu-iotests: allow passing unittest.main arguments to the test
    scripts
  qemu-iotests: move command line and environment handling from
    TestRunner to TestEnv
  qemu-iotests: let "check" spawn an arbitrary test command
  qemu-iotests: fix case of SOCK_DIR already in the environment
