Currently run-tests must be called from the Buildroot top directory.
Derive the top directory from the script path, so run-tests can be called from
any path.
As a consequence the test infra will always test the repo it belongs to.

More and more packages being tested by the test infra, e.g. syslog-ng,
need entropy at startup, usually reading from /dev/random.
Some test cases can also depend on a kernel version newer than the
builtin ones already provided by the test infra:
- 3.11.0 for armv5;
- 4.0.0 for armv7.
Add a new builtin kernel to be used by such test cases.
Add it for armv5 so most test cases that switch to use this kernel can
keep using BASIC_TOOLCHAIN_CONFIG.
Use the same kernel version and kernel config as qemu_arm_versatile plus
HW_RANDOM_VIRTIO for VirtIORNG to be usable.
Copy the actual binary file from the syslog-ng runtime test at current
master @ 29e1cb8884.
Since there is already a 'kernel-versatile' file on autobuild.buildroot.net
and we must keep it with this name for reproducibility purposes, create a
simple naming convention for newer builtin kernel images and dtb files:
kernel-<defconfig>-<kernel_series_version>
<dtb_name>-<kernel_series_version>.dtb
Pass '-device virtio-rng-pci' to qemu when this kernel is used.

The git tests don't need to do a full build, they only need to do a
configure and download and/or legal-info. More tests of that type will
be added in the future. Therefore, we want to have a test base class
that doesn't automatically do a full build in the setUp().
Add this new class as a superclass of the existing BRTest class, so we
don't need to update existing tests. Only the code in run-tests that
iterates over all subclasses of BRTest has to be adapted to use
BRConfigTest instead.

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.

Since commit cf3cd4388a the -j option is
silently ignored.
The configuration lines are processed using '\n'.join().
This function adds intervening occurrences of the separator, but the
resulting string does not end at a separator.
>>> "n".join(["a","b"])
'anb'
It results in a defconfig that does not end in a newline.
When BR2_JLEVEL is added by -j logic to the defconfig it ends up
concatenated to the last line of the defconfig.
BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_ARM=yBR2_JLEVEL=7
The resulting .config has the default BR2_JLEVEL=0.
Instead of just workaround this problem by adding a newline before
BR2_JLEVEL when -j is used, make the defconfig to end in a newline since
it is a more future-proof solution.

In commit b78b50465c, the initialisation
of BRTest.builddir was moved to the __init__ function. However, it is
set based on BRTest.outputdir and that is only set when the -o argument
is given to run-tests. When called as "run-tests -l", there is no -o
argument so BRTest.outputdir remains unset.
To fix, keep BRTest.builddir at None when BRTest.outputdir is None.
While we're at it, drop the direct access to the class member. If a
subclass wishes to set outputdir to something else before calling
BRTest.__init__, they are free to do so.

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!
