Move tests to the plugin's own directory.

And drop the notion of a "multiplex capable" Avocado.  If the plugin is
installed, then we assume the dependencies have been fulfilled.  The plugin
presence is used then for the creation of the test suite, including the
plugin's own tests.

We rely on garbage collector to run __del__s before we check all tmpdirs
were cleaned. Let's force-run gc.collect() and (just to be sure) run
sync.

We used to use increased verbosity to get name of the test which left
tmp dirs behind, but it is not necessary. This commit decreases the
verbosity and only logs the error as well as test name in case this
failure is detected.

This commit enables the left-behind-temporary-dirs check between each
test. As all selftests are executed as a single process the BORG class
keeps the TMP dir of the unit-tests. To avoid results spoiled by this
fact this commit adds a force-cleanup of the tmp dir tracker overriding
the BORG internal state, which is not really nice, but for selftests
acceptable.

The method to clean it was especially named
"unittest_refresh_dir_tracker" to emphasize it should not be used
outside of unittest.

The unittest standard library on Python 2.7 an later has everything
that the unittest2 backport is supposed to have.  Let's then drop all
the conditional imports of unittest2 and stick with unittest.

Recent pylint update is more pedantic about module level spacing. There
are no changes to code, only couple of extra spaces to make it happy.

Currently the fail-fast works per section (pylint style, unittests, ...)
but this patch enables it also inside the unittests, therefor it
finishes with the first failed unittest finishing even quicker than
before.
Note that this option is incompatible with the parallel check.

The way we built the unittest runner will happily
ignore errors, which is bad from a CI standpoint.
Let's ensure that errors don't go unnoticed by
analyzing the results object and see if it's got
errors or failures.

The unittest module, and unittest2 backport on Python 2.6, is capable of
finding unittests and running them. So, effectively, we do not need nose
at all.

This patch removes the dependency on nose, replacing the run script
with a version based solely on the unittest module.

One change of functionality is that run now looks and runs tests in the
standard selftests directories (unit, functional, doc), and does not
accept command line arguments. If one wants to run a subset of them,
it's pretty easy to just use the unittest module for that:

 $ python -m unittest discover -s selftests/unit

Clean up imports inside the avocado code tree. This

Remove the license text from files inside docs, examples and selftest,
to keep the license text only in relevant parts of the project.

Usually coverage and xunit are unused and only slows down CI. This patch
disables it by default. In order to get coverage please run

In order for people to run all avocado tests at once,
move and reorganize tests under a directory called
selftests. For someone to run all self tests in
avocado, one would have to execute:

    selftests/run selftests/all

This is a shortcut for developers. .travis.yml
was also updated to run tests based on the new
directory structure.

I went through all python files in avocado code, and
some changes were made:

* Files entirely written by the current avocado dev
team were changed to be GPL v2+
* Files with a significant portion of code derived
from autotest remain GPL v2 strict, and original
authorship was re-established
