For whatever reason most of the files had their permission
changed from 644 to 755, which is not wanted.

Changes after the merge with L1_renaming in order to work at least in FDD mode. We need to handle the RU_mask_tx for TDD mode.

Since VCD has now to go through the T tracer, we enforce the consistency
of data found in common/utils/LOG/vcd_signal_dumper.[ch] with data
found in common/utils/T/T_messages.txt.

We might get completely rid of common/utils/LOG/vcd_signal_dumper.[ch] at some
point. For the moment, let's keep it.

This commit adds the program common/utils/T/check_vcd.c and necessary
modifications to enforce its use at compilation time.

If you modify common/utils/LOG/vcd_signal_dumper.[ch] but do not update
common/utils/T/T_messages.txt an error will pop up when you compile the
software. You have to keep both modules synchronized.

log.c simplification, fix usefull functionality which never worked, move all log code from openair2 to common

Log review step 1: legacy VCD removal, LOG macro modified, TTracer enabled at build time by default, in a way it, by default configuration,  provides console logs, as in previous versions

It has been chosen to not include the full history of commits
from David. He included a binary version of wireshark, probably
a modified one that understands NFAPI. Wireshark is released under
the GPL license, we cannot include it in the repository. We could
have done a next commit to remove this binary. But then it would
still be present in the history of commits, which may not be allowed.
And it would take space on disk. We could edit the history to remove
wireshark entirely. But this operation is too complicated.

There was also a pcap capture file, which has nothing to do in
the history of commits and would take space on disk. There again,
it's too difficult to edit the history to remove it.

There was a file .gitignore that was also removed.

The original history can be found on David's repository:
https://gitlab.eurecom.fr/daveprice/openairinterface5g/
The branch is: nfapi-ru-rau-split.

A copy of that branch has been included in the internal OAI
repository, for those who have access to it.
The branch is the same. The last commit ID is
9106438239e0bc626ff1fa1d97d911caadd0fbb9.

You can compare the current commit with the commit 9106...
to see what differs.

The current commit has to be considered non-working.
The commit following the current commit will fix problems with
the work in the current commit.

If you use git bisect, don't spend time analyzing the current
commit.

several problems were present:
- there was no comma after "ue0_trx_write_ns_missing" in the array
  eurecomVariablesNames;
  comma was put, and also commas for the last element in the array,
  which doesn't hurt and will prevent future problems
- bad order of values in eurecomVariablesNames, which
  was different from the enum vcd_signal_dump_variables;
  order was checked and fixed
- strange/wrong use of VCD_SIGNAL_DUMPER_MODULE_END/LAST;
  the whole logic was removed/simplified
