From 3b8100721032397f507b93c059d3dec0365c7eb0 Mon Sep 17 00:00:00 2001
From: Andreas Eversberg <jolly@eversberg.eu>
Date: Sat, 19 May 2018 10:56:43 +0200
Subject: Refactoring command line option handling

 * Use own function to define and parse command line options

 * Command line options can be defined by config file also

 * --limesdr allows to auto-set required SDR option for LimeSDR
