The function may return NULL if the UE has been dropped
in the PHY layer but is still present in the MAC layer.

Deal with the NULL case everywhere it's needed.

This is the real fix, d5a6817887e720935d9dcc0a6f7d632e85c7d8e5
was not the right solution.

I am not sure this is the correct solution.

The problem seems to be that the RRH GW does not use ITTI
and thus the type 'as_nas_info_t' is not defined, and then
the compilation fails.

The simple fix is to include 'as_message.h' in
'openair2/RRC/LITE/defs.h' if ENABLE_ITTI is not
defined. Maybe it's not good. RRH GW compiles with this fix.

"frame" is not defined, we pass 0 instead.

Maybe not the right solution.

It is defined both in openair2/COMMON/commonDef.h and
openair2/COMMON/platform_types.h.

Removing one or the other definition creates many problems
when compiling this or that part of the system (ue_ip.ko,
at_nas_ue). Let's keep both and protect the definitions
inside #ifdefs.

I'm not sure this is the right fix, so I put a LOG_TRACE
that is displayed when the code comes here.

I chose to remove it from common/utils/itti/itti_types.h,
maybe it's not the correct solution.

Several various fixes are included. Not sure what component of
the system uses this file.

There is one 'abort' added in case a fscanf fails. It may be a
bit too brutal.

This is not absolutely necessary (the processing is ok),
but the warning is annoying.

I forgot one file in the previous commit

Some of them might not be correctly handled.
I put /* TODO: XXX */ where I didn't know if
the fix was correct.

init_nas_s1 may not work properly, but many people complain
about this file, so let's put it in the repository.

We'll fix it at some point if it's not properly usable.

The LOG_X macros emit a lot of warnings when compiling with the T
because they call the function logRecord (or logRecord_mt)
which has not been "marked" as calling printf, so gcc won't
emit typical printf warnings.

With the T, they directly translate to sprintf, so those warnings
pop up, much more verbose due to several macro expansions.

Let's make them pop up all the time so it's easier to fix them.

The throughput for the bandrich dongle was limited to 13Mb/s in downlink
UDP with iperf, with lots of packets lost (we sent 15Mb/s). TCP was
working fine.

Replacing /dev/ttyUSB2 by /dev/ttyUSB0 for wvdial solves the issue.

We also had to have separate data/control links. (See bandrich.txt
in cmake_targets/autotests/v2/actions for full details.)

calling the function for FDD case executed code for TDD case.

The old one is still usable by replacing .gitlab-ci.yml with
the previous version.

As reported on the mailing list, there was a problem
for some users. The link phase of building the simulators
was giving the error "undefined reference to ATL_scopy".
