33f3cb8a87 support/run-tests: export download dir
Currently, the download directory, when specified with the -d option, is
only used to store the files downloaded by the testing infra, not those
downloaded by Buildroot.

So, we end up with this situation:

    BR2_DL_DIR  | -d DIR   | test downloads   | BR downloads
    ------------+----------+------------------+--------------
    unset       | unset    | [error]          | [error]
    unset       | set      | in $(DIR)        | in $(TOP_DIR)/dl
    set         | unset    | in $(BR2_DL_DIR) | in $(BR2_DL_DIR)
    set         | set      | in $(DIR)        | in $(BR2_DL_DIR)

This is not very consistent.

We change the behaviour so that the value of -d always takes precedence,
and is used by Buildroot as well, giving this new behaviour:

    BR2_DL_DIR  | -d DIR   | test downloads   | BR downloads
    ------------+----------+------------------+--------------
    unset       | unset    | [error]          | [error]
    unset       | set      | in $(DIR)        | in $(DIR)
    set         | unset    | in $(BR2_DL_DIR) | in $(BR2_DL_DIR)
    set         | set      | in $(DIR)        | in $(DIR)

ef8d1f1b15 support/testing: fix code style
Fix the trivial warnings from flake8:
 - remove modules imported but unused;
 - use 2 lines before class or module level method;
 - remove blank line at end of file.

ebe61135c9 support/tests: use relative test_dir
When we list the available tests, we use test_dir, which is set from
the path of the script. However, when we run the tests, we use the
hard-coded path.

Ditto to find the config file.

For consistency, always use test_dir.

6e45e33f27 support/testing: allow to use a multiplier for timeouts
Add a parameter to run-tests to act as a multiplier for all timeouts of
emulator.
It can be used to avoid sporadic failures on slow host machines as well
in elastic runners on the cloud.

f98b93daaa support/testing: run testcases in parallel
Let the user to pass -t to set the number of testcases to run
simultaneously.

When -j is not specified, calculate it to split the available cores
between the simultaneous testcases.

Example of auto calculated -j for cpu_count 8:
  -t -j  total
   1  9  9
   2  4  8
   3  3  9
   4  2  8
 >=5  1  t

fa3c5cad44 support/testing/run-tests: help: put the one-letter form before the long form
This is what the manpages usually do, and what Python does with the
automatically-added -h/--help parameter:

Before the change:
  $ ./support/testing/run-tests
    [...]
  optional arguments:
    -h, --help            show this help message and exit
    --list, -l            list of available test cases
    --all, -a             execute all test cases

After the change:
  $ ./support/testing/run-tests
    [...]
  optional arguments:
    -h, --help            show this help message and exit
    -l, --list            list of available test cases
    -a, --all             execute all test cases

a732fb222b support/testing: core testing infrastructure
This commit adds the core of a new testing infrastructure that allows to
perform runtime testing of Buildroot generated systems. This
infrastructure uses the Python unittest logic as its foundation.

This core infrastructure commit includes the following aspects:

 - A base test class, called BRTest, defined in
   support/testing/infra/basetest.py. This base test class inherited
   from the Python provided unittest.TestCase, and must be subclassed by
   all Buildroot test cases.

   Its main purpose is to provide the Python unittest setUp() and
   tearDown() methods. In our case, setUp() takes care of building the
   Buildroot system described in the test case, and instantiate the
   Emulator object in case runtime testing is needed. The tearDown()
   method simply cleans things up (stop the emulator, remove the output
   directory).

 - A Builder class, defined in support/testing/infra/builder.py, simply
   responsible for building the Buildroot system in each test case.

 - An Emulator class, defined in support/testing/infra/emulator.py,
   responsible for running the generated system under Qemu, allowing
   each test case to run arbitrary commands inside the emulated system.

 - A run-tests script, which is the entry point to start the tests.

Even though I wrote the original version of this small infrastructure, a
huge amount of rework and improvement has been done by Maxime
Hadjinlian, and squashed into this patch. So many thanks to Maxime for
cleaning up and improving my Python code!
