A better solution has to be found.

One of the optimized RE allocation function does not work properly
and generates some decoding errors with a COTS UE. Let's use the
generic function for the moment, while analyzing what is wrong.

more flexible to support 4x4 system.

remove compilation warnings, especially when disabling T_TRACER. enhance LOG_M macro implementation, introduce LOG_DEBUG_XXX macro to replace #ifdef DEBUG_XXX

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

2. minor modifications in dlsch_demodulation.c for 2 eNB TX antennas, 1 RX antenna. Inconsistant indexing of some arrays in this case.
3. change in config_load_configmodule.c : removed exit(-1) when no configuration file is used. This makes unitary simulators exit. Effect on lte-XXsoftmodem TBC.

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
packs multiply-adds 16 bits and packs into 4
blocks of 32 bits.

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}.

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.

to linear_preprocessing_rec.c.
2. Adding linear_preprocessing_rec.c to PHY_SRC_UE library.
3. Adding mmse_flag and mmse functionalities to dlsch_demodulation.
4. For now, dlsim_tm4 will not compile.

as more transparent functions independent from the number of
resource elements in RB. They will tream as many resource
elements as there is in the vector that is passed.
