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.

Move the strip out of leading spaces in defconfig fragments from the
BRTest class to the Builder class. It actually postpones the strip out,
consequentially allowing test cases to post-process the defconfig in
their own __init__ before calling the __init__ method from BRTest.
Moving this code to the Builder class also allows any new test class
that inherits from BRTest to reuse the same code even if the new class
overrides the setUp method.
At same time, prepend a newline to the jlevel handling otherwise it
would stop working for defconfig fragments that don't end in a newline.

The defconfig is composed on-the-fly by test infra + tests.
Dump it to the logfile before running 'make olddefconfig' so it can
easily analysed when debugging.

We currently call infra.smart_open() to open log files each time we
need to write to them.
Opening the file once in the constructor of Builder and Emulator and
writing to it whenever needed is simpler and slightly more efficient.
Remove smart_open and instead create a new open_log_file() function
which just opens the logfile. Also let it compute the filename, in
order to simplify even further the Builder and Emulator code.

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!
