make the common runtime optional
In order to achieve really tiny firmwares, make our runtime (tasks, hooks, muxed timers, GPIO abstraction ...) optional. Add 2 new build options for it : CONFIG_COMMON_RUNTIME and CONFIG_COMMON_GPIO which are enabled by default, and ensure all the source files are built according to the right configuration variable.
