  docs: make contribution licensing terms (DCO style) more explicit

Let's add the recommended (legal) language that will let our
contributors know what a "Signed-off-by" line means when sending
contributions to Avocado.

The default exception of `subprocess.Popen` does not contain any useful
info. We already replace the original exception for "File not found"
exception, this patch always modifies the exception's message to include
the executed command.

Let's add a check that teststmpdir is shared across different jobs when
set manually via environment variables. This also contains a little
improvement in one of the used tests.

The "AVOCADO_TESTS_COMMON_TMPDIR" is an environmental variable name used
to store the location of a common tmpdir. To avoid issues with
typos/name changes let's use the variable in `avocado.core.test` to
share the env variable name everywhere.

The filtering is not useful for basic params, let's move it to mux and
while on it also remove the avocado arguments (options) to the
yaml_to_mux plugin.
Signed-off-by: NLukáš Doktor <ldoktor@redhat.com>

The `avocado.core.tree` contains multiplex/mux-related features like
multiplex and ctrl, which are not really useful for basic params. Let's
simplify the base tree object and put the extracted features in
`avocado.core.mux`.

This is a first step and the `avocado.core.mux` should contain most of
the generic parts useful for creating varianter plugins.

The `_create_from_yaml` function allows specifying custom tree node
object, but it only works properly with `tree.TreeNode` inherited ones.
Let's use the custom class instead to make the code cope with different
use cases.

For speed optimization we used to override the "data_inject" and
"data_merge" methods after parsing. Let's stop doing that as the check
should not be that costly and add a support for
`Varianter.ignore_new_data` attribute to allow ignoring new data on
parsed Varianter.

The concept of multiplexer is about to be split into an abstract API for
variants generation, multiplexer which will be in-core implementation of
one of the variants generation plugins and yaml_to_mux plugin which uses
this multiplexer implementation to create variants from a yaml file.

  avocado.utils.pci: Check the full path in get_slot_from_sysfs
  avocado.utils.pci: Fix get_num_devices_in_domain

The get_slot_from_sysfs checks for devices' directory, but not for the
actual file and this file is only available on ppc64. Let's improve the
check and report None when the file does not exists rather than failing
with IOError exception.

The get_num_devices_in_domain uses wildcards, which are handled by
shell, which was not enabled in the command.

  plugins: tests temporary directory

This commit creates a job pre/post plugin that generates a temporary
directory intended to be consumed by the tests. The temporary directory
will be created in 'pre', available via environment variable and removed
in 'post. We are also exposing the tests temporary directory in the Test
API.

The len(string) does not work properly when terminal control characters
are present. To allow printing them, we first need to calculate the
length of the string without the term ctrl characters and then print it.
We can't use the "%-{NUM}s" formatting, because it again uses the
incorrect length, so instead this patch uses custom padding calculated
from the stripped lengths.

As a side effect the custom formatting this version allows rows with
different number of cols in it. I left it untreated and added selftest
for it as I think it could be actually useful.

Let's avoid duplicating the code and use `itertools.chain` to treat

  docs: cross-reference for test tags in 'Test discovery'

From test writer perspective, we need the information about test tags in
the Writing Tests section. But from the users executing tests
perspective, the information about test tags should be present in Test
Discovery section. Let's fix that creating this cross-reference.

I tried to strip-down the bootstrap library in order to minimize
resources size. I used brute-force based on me not being able to find a
visible difference, so I can't guarantee everything is included, but I
tried hard and couldn't see a difference.

Default bootstrap library contains a custom font we don't really use.

Let's increase the GDB init timeout up to 5s and while on it improve a
bit the while condition.
Signed-off-by: NLukáš Doktor <ldoktor@redhat.com>

On heavy loaded machines (mainly IO) it might happen that test's
`__init__` is not executed in 10s causing the execution to fail. The
same applies to when we try to interrupt the job, only here the default
timeout was 0.5s. Let's increase both to 60s, they are both busy loops
so this timeout is only a corner case.
