remove L1L2 task, also remove some call to send messages to UNKNOWN_TASK, removed in new itti. Align LOG in rlc sources with new LOG code (remove DEBUG_RLC...)

exit softmodem when a command line option requiring an argument is specified without an option value. Previous behavior was to print a message and ignore the option

For whatever reason most of the files had their permission
changed from 644 to 755, which is not wanted.

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

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
