Now the llrs after SIC procedure are updated.
In dlsim_tm in case of TB0_active==-1,
the llr were taken from the wrong buffer, and in dlsch_demodulation
the SIC llrs were written into the wrong buffer in the same case.

The presence of one or the other may lead to some failure/crash in
some situations.

This generates too much prints and may disrupt realtime.
This has to be off by default.

The files NativeInteger.c.diff and constr_SET_OF.c.diff
from asn1c were generating compilation warnings. We had
local patches applied on generated files by asn1c.

A new version of asn1c has been pushed to
https://gitlab.eurecom.fr/oai/asn1c
(commit 224dc1f991b7e7ad705ce92e171b942f87b7b7e7)
making obsolete the fixes we do here.

So we now remove those fixes.

Everyone should update their asn1c installation.

The simplest is to do:

    source oaienv
    cd cmake_targets
    ./build_oai -I
