fix command line parsing for config_getlist, also improve help processing and fix probe (opt) parameters processing

For whatever reason most of the files had their permission

Add a parameter to load_configmodule API to allow an exec to specify that it may be run with only  command line options

fix bad build_oai directive to compile libconfig for phy-simulators, fix load_configmodule crash because config source not set.

abort execution when an unknown option is passed via the command line: add config_check_cmdlineopt API to config module, create lte-softmodem-common.c source to remove duplicate code in lte-softmodem.c and lte-uesoftmodem.c, fix segfaults in exec_function of lte-uesoftmodem

removing reference to uesoftmodem from load_configmodule (don't understand why this dependence is there in fist place. Also makes unitary sims break)

removing reference to uesoftmodem from load_configmodule (don't understand why this dependence is there in fist place. Also makes unitary sims break)

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.

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

remove getopt call in configuration module, it changes the argv order. Fix configuration module bugs (command line arguments sometimes not properly processed

Improve configuration module error management at init time, Fix command line help option processing, remove shotopt field from parameter structure

lte-softmodem -O <config file> will trigger legacy config mode
ltesoftmodem  -O libconfig:<config file> will trigger configuration module usage.
