Just use classes introduced in previous three commits. Behavior
difference is described in these three commits.

Drop group file, as it becomes unused.

The assertion means that giving an unknown option results in an error
message like this:

$ build/check -T -raw
Traceback (most recent call last):
  File "/home/kwolf/source/qemu/tests/qemu-iotests/build/check", line 41, in <module>
    assert not tr.remaining_argv
AssertionError

I think this could be a bit friendlier (especially since this doesn't
even tell you which of your options was wrong).

The bulk of the work was done in the earlier patches, and my python
review is weak; but I can confirm that with this patch applied, my usual
attempts at running ./check still appeared to work for me.  That's not
the same as proving you did 1:1 feature translation (and in fact, your
commit message documented dropping some features like -v), but if 'make
check' and CI tools still run, I'm okay leaving it up to developers to
complain about any other feature that they used but which go missing (or
to implement it).

You may want to claim 2021 as well.

A lot shorter for the main engine ;)

I will *try* to give this a look, but I am still buried under post-PTO 
mail; and I feel comfortable with Kevin's Python review otherwise, so 
don't hold your breath waiting to hear from me.

-# QA groups control file
-# Defines test groups
-#
-# Some notes about the groups:
-#
-# - do not start group names with a digit
-#
-# - quick : Tests in this group should finish within some few seconds.
-#
-# - img : Tests in this group can be used to excercise the qemu-img tool.
-#
-# - auto : Tests in this group are used during "make check" and should be
-#   runnable in any case. That means they should run with every QEMU binary
-#   (also non-x86), with every QEMU configuration (i.e. must not fail if
-#   an optional feature is not compiled in - but reporting a "skip" is ok),
-#   work at least with the qcow2 file format, work with all kind of host
-#   filesystems and users (e.g. "nobody" or "root") and must not take too
-#   much memory and disk space (since CI pipelines tend to fail otherwise).
