The external runner tests currently do not support the extended API for
simple tests. This patch moves the extended API into the
`SimpleTest.execute_cmd` in order to run this from inherited tests like
ExternalRunner.

Note this version affects all tests which share the
`SimpleTest.execute_cmd`. I think it's a good think, but I'd be also
fine with implementing it as another SimpleTest method and call this
method from inherited tests where it makes sense (like ExternalRunner).

The `avocado.utils.pci` library incorporates many functions related to
pcis and some functions accept only full pci address, some partial and
some only special format (domain+bus, ...). Let's explicitly distinguish
by using:

* pci_address - for any segment of pci address
* full_pci_address - for full pci address only
* dom_pci_address - for special usecase where domain is required

The `get_num_devices_in_domain` function reports all matches in
`/sys/class/*/$PCI`, which is not really a list of devices handled by
the $PCI, but it's a list of interfaces available to given device's
function.

This function supports partial matches, so it allows listing not just
one function's interfaces, but also one device/bus or even all
interfaces associated to pci domain, so let's be a bit more explicit
about the usage.

  Makefile: adjust PyPI packaging/upload

Since we favor the creation of a tarball with "git archive", PyPI gets
sensitive every now and then with our uploads.  Since the 42.0
release, pushing the new packages to PyPI would result in Server
Errors.

This adds the PKG-INFO to the tarball that will be uploaded, which
seems to fix the current errors.  Also, since it's now a single file,
it can be pushed with the "twine" command line application.

Alternatively, we could double check our file manifest, and rely
entirely on setuptools to generate the tarball.  But, I'm not a big
fan of adding files to version control, and then to a manifest of any
sort.

Note: in the past, this was also necessary because of the tweaks to
the information inside the PKG-INFO file, namely the package name
(avocado -> avocado-framework).

  Remove argument support for SIMPLE tests

To provide support for passing arguments for simple tests in command
line, we were creating some cases where the test reference could not be
properly handled. Also, for test references with white-spaces, we have
an inconsistent behavior. See reference.

This patch removes the support for arguments in test references,
restoring the proper behavior, which is expected to be shell-like.

As consequence, we now handle correctly white-spaces in tests references
as well as Unicode characters.

Currently we check the first commit differently, then all the other

the "make check" similarly synoptic so there is no need to treat the

The len(string) does not work properly when terminal control characters
are present. To allow printing them, we first need to calculate the
length of the string without the term ctrl characters and then print it.
We can't use the "%-{NUM}s" formatting, because it again uses the
incorrect length, so instead this patch uses custom padding calculated
from the stripped lengths.

As a side effect the custom formatting this version allows rows with
different number of cols in it. I left it untreated and added selftest
for it as I think it could be actually useful.
