is currently licensed under GPLv2+, so make that clear in the documentation.

avocado.runner: optimize the run of quick tests

Signed-off-by: NLucas Meneghel Rodrigues <lmr@redhat.com>

If the test is very quick, it may run in less than 0.1 secs, which is the
minimum time we wait for the result to be available in TestRunner::run_suite().

Since utils.wait_for() accepts a "first" parameter, documented as "Time to sleep
before first attempt", let's use it with a very aggressive low value, just
enough for the main process to be put to sleep by the scheduler and give time
for the other process to run.

Benchmark using multiplextest:
    $ TESTS=""; for f in $(seq 1 100); do TESTS="$TESTS examples/tests/multiplextest.py"; done
    $ time scripts/avocado run $TESTS > /dev/null

Before this change:
    real    0m12.114s
    user    0m1.549s
    sys     0m1.038s

After:
    real    0m2.639s
    user    0m1.065s
    sys     0m0.764s

Now that we gather values from the config files, 'Current'
becomes more proper term.

avocado.test: Add missing argument to test.MissingTest

When importing of the test fails, it's class is set to MissingTest
and then it's executed. But running requires runner_queue param.
Without it the test fails and Avocado hangs for infinity for early
status.

avocado.core: Rename 'runner' config section to 'datadir.paths'

Strictly speaking, the test runner is a plugin just like any
other, besides, what is being configured there is in fact datadir
paths, hence the rename.

Nosetest by default doesn't like executables, I find it
useful when developing to see how nosetest executes our
tests. Besides, it shouldn't modify the results of our
custom made suite.

avocado.multiplexer: Add support for including files and removing node/values [v1]

This patch adds support for '!remove_value' yaml tag. It can be used
to remove certain value from previously existing values. This happens
during merge before value is updated.
Signed-off-by: NLukáš Doktor <ldoktor@redhat.com>

This pach adds support for yaml tag "!remove_node", which during the
merge removes the node defined in previous tree. This happens only
during merge, before new children are added.

Support for '!using' flag. It extends the current leaf location
of the provided path. It can't completely change the location,
it only extends the base.

This patch defines "!include" tag for inserting other files from within
the yaml file.

Keep in mind that it's necessarily to separate the ':' from the tag,
otherwise yaml thinks it's a different tag.

avocado.multiplexer: Support for debug run [v3]

This complex patchset adds debug version of yaml parser. It stores
the origin of each value from environment. For list it stores
per-slice origin too.

Debug mode is NOT suitable for run-ner, only for multiplex-er. It
corrupts the values by adding the origin after the value.

The unittests were adjusted and enhanced. I added explanation into the
examples/mux-selftests.yaml describing what the weird names stands for
and what they test. I added couple of check which stress the old tests
and couple of them test the new features.

Usually we create single tree and then multiplex it's values. This
generates lots of TreeNode.environment calls. This patch caches
TreeNode.environment calls and returns last known version.

There is one drawback, in case you modify tree structure after calling
TreeNode.environment you must call TreeNode.set_environment_dirty,
otherwise you get the outdated results.

avocado.aexpect: Don't use a predictable, non system wide tmp dir

Instead of using /tmp/aexpect, use per aexpect instance
directories, tied to their aexpect ids (that are randomly
generated). This way we fix the potential security issue,
and also, clean up more efficiently the aexpect tmp files
(all is gone upon the .close() method happens, or garbage
collection - whatever happens first).

Put a DEBUG flag on the aexpect module, that will leave
the tmp files in case people want to debug the code.
