A few extra configurations needed for the Python 3 builds running on Travis-CI.

Merge branch 'travis_configuration_python3' of https://github.com/clebergnu/avocado into clebergnu-travis_configuration_python3

The environment that Travis-CI sets up is somehow broken with regards
to the requirements for six.  The exact message we get and running
selftests/run is:

   pkg_resources.ContextualVersionConflict: (six 1.9.0
   (/home/travis/virtualenv/python3.4_with_system_site_packages/lib/python3.4/site-packages),
   Requirement.parse('six>=1.10.0'), {'Fabric3'})

Let's bump the requirements to 1.10.0, to try to help Travis-CI.

pylint catches what the (on purpose) nasty example test does with:
"Raising a new style class which doesn't inherit from BaseException".

But, since that's on purpose, let's silent pylint instead.

The HTML plugin is using the `subprocess` library to fire up the
web browser that will show the report.  In theory, we could be
using our own `avocado.utils.process` for that, but given the
comments in that section, I believe there may be caveats.

As a fix for the immediate issue at hand (pylint catching a failure on
a Python 3 environment about using `file`), let's just use the
definitions from the `subprocess` module itself.

Instead of comparing a string against the exception, and relying
on its conversion to a string.  This approach is undesirable and

This lock doesn't prevent, say, multiple drainers from writing to

see how it has any purpose at all.

avocado.utils.process.system_output() is a utility function that has the
goal of returning the process output only.  Let's use it instead when
that's the only goal of the calling code.

These classes and methods have knowledge about the YAML files, and the
YAML to Mux plugin is the only user of those.  this plugin.  So it
makes sense to move it to the plugin module.

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.

This change enables plugins tests to also be run in parallel, if
they exist.

Because the "selftests/{unit,functional,doc}" directories are valid
Python modules, that is, they contain `__init__.py` files and can
be imported by the unittest runner, no special handling is necessary.

But, since the complete path for directories which (can) hold plugins
tests are not valid Python modules (and shouldn't be), some special
handling of directories is necessary.

Because of that, it's not currently possible to run *all* of the
tests (from "core" selftests and from plugins) at the same time.
A future enhacement would be to better schedule processes that
can be loaded from the same path at the same time, but all of
them at once with global "test slices".

Some versions of the unittest mock library cannot easily deal with

of coming up with cumbersome code to support them on all (ancient)
versions.
