This commit emoves the warning:
make[4]: warning: jobserver unavailable: using -j1.  Add '+' to parent make rule.

Basically, inside a Makefile we should use $(MAKE) instead of make.

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
cmake_targets/CMakeLists.txt an error will pop up when you compile the
software. You have to keep both modules synchronized.

Use "error:" as prefix to error messages in genids.c
to help looking for errors in case of failure of
the build.

Don't use shm anymore. Use mmap directly.

Pass the command line arguemnt -vcd to trace all VCD variables
and functions.

Make it compatible with 'template' gtwave files as found in openair's
repository.

The type VCD_NAME was added to the VCD IDs in T_messages.txt.
The database processing code was adapted to use it.
The tracer to_vcd was adapted to use it and render the produced vcd
output compatible with the 'template' gtkwave files.

When running to_vcd, do not forget to pass -vcd to use this feature.

This tracer allows the connection of several tracers to one tracee.

To use the multi tracer:
- run the tracee as usual, eg. ./lte-softmodem -O xxxx.conf --T_stdout 0
- run the multi tracer: ./multi -d ../T_messages.txt
- connect other tracers to the multi tracer:
   - ./enb -d ../T_messages.txt -p 2022
   - ./textlog -d ../T_messages.txt -p 2022
   - etc.

By default the multi tracer connects to the tracee to the port 2021,
as for any other tracer.

Then it accepts connections from other tracers on the port 2022.

This can be changed with parameters on the command line.

The tracee and the other tracers can be stopped/started at any time.

- bug fixed in ue and enb tracer: the socket needs to be closed
  in case of restart
- cleanup: fix spacing in T_messages.txt

minor modifications to lte-ru.c and ru_control.c.  Addition of lte_noS1_buildCMakelists.template which somehow got removed.
