- use OAI location to retrieve asn1c
- use a specific commit instead of a branch name

This was used for the ITTI analyzer.

The ITTI analyzer is now to be considered obsolete.
The source code will be removed at some point.

receiver. THe proposed solution is to replace the average channel level with
median  = (max+min)>>1.
For these reasons lsch_channel_level_median is introduced.

instead of _mm_srai_epi16
_mm_srai_epi32 should be used as _mm_madd_epi16

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

Add `autoreconf -iv` in build_helper to create configure file for asn1c.

1. It's no need to modify LTE-RRC's ASN.1 file for enabling option group
   feature in generate_asn1.
2. It's no need to patch the C header files generated from
   LTE-RRC/S1AP/X2AP's ASN.1 in fix_asn1.
3. It's no need to pre-process S1AP/X2AP's ASN.1 for enabling information
   object class feature by asn1tostruct.py.

This commit requires an un-official version of asn1c which are
collaboration of asn1c community members and `build_helper` is modified
in this commit accordingly :

  https://github.com/brchiu/asn1c/tree/velichkov_s1ap_plus_option_group

This asn1c can also convert ASN.1 of 5G NR RRC (38.331, v15.1.0) and
generate C files with -findirect-choice command line option without
tweaking ASN.1 file.

Examples for how to use this asn1c for S1AP are in S1AP files, e.g.
s1ap_eNB_nas_procedures.c and s1ap_eNB_handler.c.

There is an modified openair-cn (based on tag 0.5.0) with this new asn1c at :

  https://github.com/brchiu/openair-cn/tree/new-asn1c

Basic S1AP interaction and data transfer operation between OAI eNB and
this modified openair-cn has been tested.

Note: Community version of asn1c is keeping evolved to provide better usage.

fix: avoid assertion when terminating lte-softmodem process.

2. Remove get_pmi from  PHY_SRC_UE and add it instead to PHY_SRC_COMMON.
3. Linking lte-uesoftmodem and lte-uesoftmodem-nos1 targets with ${ATLAS_LIBRARIES}.

T tracer configuration identical for all executables, no ref to T Tracer config variables (T_port, T_wait...) outside the T tracer

1. Moving get_pmi into a separate file and making corresponding
changes in CMakeLists.txt.
2. Creating PHY_MEX library with functions required for the receiver
mex-functions.
3. Making necessary changes in defs_UE.h so that mex-functions
do not complain about multiple LOG_ calls.
