avocado/utils/process.py: avoid false positives on pid_exists()

The current implementation of pid_exists() is such that, if any error
condition is obtained from sending a signal to a given process, than
it means that it doesn't exist.

But that is not true, and the same OSError exception raised when the
process doesn't exist, can be raised when there's no permission to
send a signal to a process (such as someone else's process).  So,
let's be very specific and check for ESRCH, which means "no such
process".

Avocado needs a bit of custom massaging to be able to properly live
under "avocado-framework" on PyPI.  This adds a target that will
make the upload of new releases easier.

avocado.plugins: Add TAP output plugin [v5]

One of the most important points of having TAP support is allowing
other tools to parse the results of the Avocado tests.  IMHO the best
way to test that we're producing sound TAP support is to use stable
implementations for that.

AFAIK, Perl is where TAP was born, and its TAP library is kind of a
reference implementation.  Let's use that, if available, to check if
our tap generation is sound.

avocado.core.test: Fix SimpleTest [v2]

No actual changes, just pylint fixes
Signed-off-by: NLukáš Doktor <ldoktor@redhat.com>

With the d6abdcd4 Test methods changed
but for SimpleTest the wrong method was chosed and only the test
execution is performed now, the post-process class is completelly
ignored. This changes the method to the correct one and adjusts
ExternalRunner to not run this postprocess.

The advanced features of SimpleTests require logging to be enabled,
which is not part of the `test` method, but the full `run_avocado`
workflow. The fact that it passed is that the advanced features were
broken for quite a long time. This patch uses the `run_avocado` which
contains the `_start_logging` and `_stop_logging` methods needed for the
advanced features to work.

Asset fetcher already uses cache_dirs and now we realized that other

available on Test() API.

The TestStatus failures are only logged to avocado.ui and not reflected
in the test's results. Let's use the method defined for runner failures
to error-out the test in case of TestStatus failure.
Signed-off-by: NLukáš Doktor <ldoktor@redhat.com>

There are two places, where runner can modify the test's status, each
handling it differently. Let's create a method to handle such occasions
in the same manner.
Signed-off-by: NLukáš Doktor <ldoktor@redhat.com>

Currently when the test reports status avocado does not check whether
the process finished, leaving open space for left-over test processes.
This patch unifies the test process handling in case the test reported
test status and allows the runner to destroy and report error in case
the test process did not finish.

Additionally it modifies the error message in case the test was
interrupted, because the original message is IMO not clear enough (I
spent quite a time analyzing how that happened and if that's an avocado
bug or supported result).

The `;` character is problematic for some makefiles, let's replace it

readable enough by human, it's guaranteed to be still unique which
concludes all requirements for machines regarding workdir.

Avocado currently does not define a set of APIs for plugin writers.
It's well understood that anyone writing plugins is really playing
under the hoods of core Avocado.

Because there's no such module namespace allocated for that purpose
alone (say, `avocado.plugin`) it was decided to put plugin interfaces
together with the "core plugin repository", that is the
"avocado/plugins" directory.  By no means the contents of
"avocado/plugins/", that is, the plugin implementations themselves,
need be the "avocado.plugins" module, it could just as well live in
"avocado-core-plugins" directory or repository.  This is also well
exemplified by the avocado-vt and avocado-virt plugins, which live in
completely separate repositories.

So, the first goal of these changes are, effectively, to make all
plugin implementations equal, always referring to
`avocado.core.plugins_interface`.  Then, the secondary goal is to pave
the way for a specific namespace to contain only the interfaces (which
should be non-core) which plugin writers should rely on.
