avocado.core.remote: Add support for multiplex files on remote machine

avocado.core.remoter: Avoid repeating of the remote command

Currently the remote loop is missing "break" so it resends the same
command until the timeout is reached.

While working on this I recreated the loop so it supports None timeout,
which is required for some operations.

Spec files Update

This patch adds support for using multiplex files and remote plugin
together. It copies all of the specified multiplex files and then
uses them in execution.

selftests/test_interrupt.py: Make test compatible with psutils 0.6

Fedora 21 ships psutils 0.6, that has the API psutil.get_pid_list()
instead of psutil.pids(). Let's make both compatible, for the sake
of running unittests on COPR builds.

avocado.core.plugins: Print traceback on failure

On plugin import failure we get the error message, which in case of
IOError is: "IOError: [Errno 2] No such file or directory". We have to
debug it or add some prints to discover, what happened. Let's add
optional traceback print in the same fashion as the "loader" does.
(the output is ignored unless the user enables "avocado.app.tracebacks")

Currently when one passes exception, which is not instance of Exception,
avocado proceeds and returns "INTERRUPTED" test instead of "ERROR". This
for example happens when old-style-class is used as exception. This
patch uses pure "except" without any argument to catch such exceptions
and then it wraps them in "exceptions.TestError" instead.

The same applies to "setUp" and "tearDown", they only use different
class as a wrapper.

The response of very slow machine with uninitilized sshd causes fabric
to raise NetworkError even though timeout was not yet reached. This
patch calls fabric in loop until the timeout is exhausted.

Initialize "root" logger as "NullHandler" to prevent other libraries
from initializing. Avocado adds file or stream handlers when it
requires them (avocado-vt).

In module avocado.core.plugins.builtin, There is a calling of
os.listdir() to iterate files in the installed python directory.

If avocado is installed in an .egg file which is compressed, it will
fail to load because that path does not really exists.

To avoid this failure, this patch set zip_safe to False explicitly.
So setuptools will install package to a real directory instead of a
zipped .egg file.

selftests/run: Ensure bad statuses trigger an exit code != 0

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.

Makefile: Allow different paths

Some people clone repositories to different names, which breaks the
"make link" functionality. This patch uses dynamic variables to support
such usage.

RFC: Makefile: Move "make link" to plugins

This patch removes the hardcoded plugin linking and instead queries all
../!(avocado)/Makefile files to link or unlink the plugins. This should
help people to deploy own plugins in the same fashion without the need
to modify avocado's main Makefile.
