After the recent update of matix, collected logs contain color codes
and we did not find the way to switch them completely off.
Replacement of "docker compose logs" by "docker logs" resolves this
issue. This commit includes changes related to "docker logs" usage.

Also, the check for clang is done in CMakeLists.txt; sleep is useless

Reset all the circular buffer to zero; this ensures that we cannot read
uninitialized data. Since this is RFsimulator, performance is not a
problem here either (and zeroing out happens only once).

Memsan complains that uninitialized reads originate because of these
warnings. Most of the corresponding variables are actually read into
through by libconfig; nevertheless, initializing them should not have a
bad side-effect (because the initialized value is overwritten).

Fix clang warning

  warning: use of GNU old-style field designator extension [-Wgnu-designator]

We access G_N at indexes that are not necessarily 32-byte aligned,
leading to segfaults. Use simde_mm256_loadu_si256() to load from memory
at an unaligned memory address to avoid the segfault.

Discovered using clang; it is unclear why gcc did not encounter the same
segfault.

-rdynamic is necessary for clang as well to properly link shared
executables. Add furthermore an option to ignore unused command line
arguments, to suppress warning

  clang: warning: argument unused during compilation: '-rdynamic' [-Wunused-command-line-argument]

This is likely because -rdynamic is only relevant for the linker, but
the corresponding option add_link_options() is only available starting
cmake 3.13, while we are still at 3.12 (for Ubuntu 18, to my
understanding).

Unlike the previous commit, in noS1, we cannot use Attach(), as noS1
automatically brings up an interface, no matter whether the connection
succeeded or not. Therefore, consistently wait a bit longer to increase
the chance that the radio is really up.

For various reasons, the UE might take longer to connect to the eNB. A
simple sleep might not be enough; instead, use Attach() to actively wait
that the UE gets an IP address. The added bonus of this function is that
it will also stop&restart a UE if it did not attach, i.e., it will try
multiple times to attach the UE.

The code (author) confused MCE_PARAMS_DESC and MCE_NETPARAMS_DESC and
tried to read the MCE name from MCE_NETPARAMS_DESC when in reality it
should come from MCE_PARAMS_DESC. This commit fixes to use the right
array.

Remove filling of broadcast_plmn, which does not exist in the
configuration.

In a previous commit, the functionality of handling IPv6 (and DNS names)
as part of the IPv4 was introduced (in IPv4 field for backwards
compatibility). This commit now removes superfluous configuration
fields:
- IPv6:  handled by IPv4 field
- active: users can just remove an entry
- preference: not needed

- Update the configuration for benetel 650 and 550 for new firmware version
- Remove the old firmware configuration file and description in the document
- Add a new RU configuration section
- Add How to get support from the OAI Community to clarify the support procedure.

Include "best practices" on how to ask questions.
