bf4a6490e4 support/testing: add fs tests
This commit adds a number of test cases for various filesystem formats:
ext2/3/4, iso9660, jffs2, squashfs, ubi/ubifs and yaffs2. All of them
except yaffs2 are runtime tested. The iso9660 set of test cases is
particularly rich, testing the proper operation of the iso9660 support
with all of grub, grub2 and isolinux.

This commit adds a few Buildroot "core" tests, testing functionalities
such as:

 - post-build and post-image scripts
 - root filesystem overlays
 - timezone support

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!
