Fix three issues with code style in our test infra:
- 'print' is now a function,
- exceptions need to be caught-assigned with the 'as' keyword,
- old-style "%s"%() formatting is deprecated.

Use an empty environment when calling make, but import PATH so the
buildroot tree under test can find binaries from the host machine.
Since environment variables are now ignored, move the handling of
BR2_DL_DIR to the defconfig to keep the current precedence of -d:
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)

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)

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.

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.

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

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!
