09a5eb427a support/testing: set $USER in rust tests
When the run-time tests to build rust and rust-bin packages are run via Docker,
the $USER environment variable is not set, which makes cargo fail when
initializing the test project.

So add it to make cargo happy.

ac260a2ace support/testing: fix Marvell ATF source code
The version of the ARM Trusted Firmware from Marvell was a Git branch,
not a Git commit, leading to unreproducible results. So let's use a
Git commit instead, which is the latest available from the branch that
was previously used.

More specifically, this branch has recently seen a fix that is needed
for ATF to build properly with recent gcc versions:

e74a7cd1e0 support/testing: fix ATF Vexpress test case
This test case currently fails to build with:

./build/juno/release/bl1/context_mgmt.o: In function `cm_prepare_el3_exit':
context_mgmt.c:(.text.cm_prepare_el3_exit+0x54): undefined reference to `cm_set_next_context'
context_mgmt.c:(.text.cm_prepare_el3_exit+0x54): relocation truncated to fit: R_AARCH64_JUMP26 against undefined symbol `cm_set_next_context'

This issue has been fixed upstream in commit
10c252c14b7f446c0b49ef1aafbd5d37804577dd, available since v1.3. So
while we bump, let's bump to the latest version of ATF, v1.5.

41a7c72c21 support/testing: add test for syslog-ng
Check:
 - the daemon is started;
 - a message is collected;
 - the daemon does not issue a warning message on startup.

When the .conf file version does not match the package version a warning
message shows up on serial on every boot. This message is generated by
syslog-ng before it is running, so it is not logged to
/var/log/messages. So in order to test the message is generated, restart
the server. It makes the message appears on /var/log/messages (since the
server is already running) where its existence can be easily tested
using grep.

bb2a57a17a fs: run packages' filesystem hooks in a copy of target/
Currently, some packages may register hooks to be run just before and
just after the generic tarball image is generated, because they need to
prepare the filesystem for read-only or read-write operation.

However, this means that, if any of the hooks or the image generation
fails, the target directory is left in a dangling, inconsistent state.

We fix that by doing a copy of target/, run the hooks on that copy,
generate the generic tarball image out of that, and get rid of the copy.

This way, we can guarantee consistency of the target directory, and we
can even ditch support for post-fs hooks (those that restore target/).

69781ebb50 support/tests: enhance the runtime systemd tests
Recent systemd bump has broken DBus dameon and DBus applications can no
longer find the daemon. So we want to catch those kind of failures
early.

We also want to check that the system as a whole is stable: no unit
should be failed.

Finally, ensure that we can read the jounrnal, even when we are doing our
tricks on read-only systems.

2b0ca5749c support/testing: fix job check-gitlab-ci.yml
Currently 'run-tests -l' is broken. It breaks 'make .gitlab-ci.yml' that
in turn breaks the job in GitLab.

TestRustBase is not a test case by itself, so it can't have a method
with the name starting with "test_" otherwise nose2 assumes it is a test
case.
Move the test_run method from the base class to the derived classes.

While at it, update .gitlab-ci.yml with the new test cases.

- building Rust compiler and Cargo from source.
- installing a pre-built Rust compiler and building Cargo from source.

For each test, a Rust test program is built and installed in the root file
system of a ARM vexpress QEMU system. The test is declared OK if the program can
be run properly from the test system.

02fc52fe59 tests: add test for post-fakeroot script
Currently, only post-build and post-image scripts were tested, each with
their own test-script.

The two test-scripts only differ in the name of the log file they
create, and it is based on the name of the script, so it is easy to
share the script.

This allows us to easily re-use it for testing post-fakeroot scripts.

144dc9ca80 boot/grub: remove
grub is no longer maintained: it is stuck at version 0.97 with huge
patches that have no opportunity to be applied upstream, as upstream
has even renamed it grub-legacy.

Besides, it no longer builds correctly with recent binutils versions,
and even the huge patches we could grab from Debian do not help the
slightest.

Since upstream really considers it dead, and there are at least two
alternatives (grub2 and syslinux), just remove grub.

Add a legacy entry.

Remove the test cases as well.

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!
