998300c5f5 testing/infra/builder: split configure() from build()
Some test cases don't use a full build as setup, so split the build()
method into configure() and build().
It allows a test case to perform configuration at the setup stage and
the build inside the test itself.

Call this new method just before build in the BRTest base class, to keep
the current behavior for existing test cases.

This change will be needed when adding a common class to test the git
download infra.

b19cb8143b testing/infra/builder: call make with empty env
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)

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.

4a1d220d9e support/testing: allow to indent ccache defconfig fragment
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.

046f968775 testing/infra/builder: dump defconfig to log
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.

d332f2c521 support/testing: simplify logging by keeping the log file open
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.

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!
