Multiplex doc: attempt to reduce confusion on file format and line nu…

Miscellaneous fixes

Ideally our HTML formatted docs would have toggable line numbers. Since
we don't have that, let's just try to be clearer about the line numbers
not being part of the multiplex file format.

This example file should have been remove together with commit
7b969527. Better late than never,
so let's do it now.

Some tests might require additional cleanups not just after the test,
but after the whole job. This patch adds another message called
"func_at_exit", which can be pushed by the test and will get registered
and called when all tests finish.

The test_status is handled in TestRunner.run_test quite chaotically.
This patch extracts test-related communication into a separate class,
and provides simple abstraction, making it simpler to extend it of
other messages.

The current probe is not identifying the version numbers

It turns out we forgot to state fabric dependencies in the
debian package. Let's fix that problem.

Let's remove an artifact from old times. The current

Add the gdebi-core dependency that our ubuntu users might need
to if they are going to use the avocado software manager
library.

It turns out that apt doesn't really handle local installs
graciously as dnf/yum, but thankfully there is a program
named gdebi, shipped in Debian and Ubuntu, that would let
us do that. Use it when available (we can make gdebi a
dependency for the avocado debian package to ensure it'll
always be there).

Fix the command used to check package status (there was
a missing space there) and the logic for checking installation
(verify OK string in the entire command output).

process.py: CmdError class backward compatibility fix

In the newer CmdError class implementation the __init__() doesn't
have anymore the third non-mandatory argument "additional_text".
But still in the different parts of the source code the
CmdError is used with the third argument. If there is no special
reason behind deleting the "additional_text" then I would suggest
to keep for having the backward compatibility.
(for example got argument amount errors while running particular
libvirt tests which had to raise a CmdError exception)

avocado/core/virt.py: avoid crashing when trying to detect VM IP address

The current code assumes that libvirt will always return information
about the VM in a given format, and also assumes that the VM will have
a NIC, which may not be the case.

This adds better checks if the conditions are not met, skipping the
IP detection feature, instead of crashing.

Together with the asset files, we'll now host the RPM repos at
a couple of OpenShift instances, named after the Avocado Project.

The two main repo files are located at:

 * https://repos-avocadoproject.rhcloud.com/static/avocado-fedora.repo
 * https://repos-avocadoproject.rhcloud.com/static/avocado-el.repo

And they point to the same base URL for individual repositories.

With recent refactorings of the loading code, some of
the logic became unreachable (and irrelevant to avocado).
Let's remove the unreachable code.

this was removed from the "Log remaining buffer on exit" fix, but it's
in-deed necessary (bfr is filled in a loop).
Signed-off-by: NLukáš Doktor <ldoktor@redhat.com>

The SubProcess logs output only when it finishes with '\n' to avoid
partial outputs. Anyway we have to print the remaining buffer on
exit, otherwise we miss the unterminated output (eg on "echo -n")

When the user provides url, which is not directory, this piece of code
tries to discover it as usual. When this fails it splits the command
using "shlex.split" and checks whether the first argument is executable.
If so it it reports it as a simple test.
