Import layer1 from osmocomBB (WIP: NOT COMPLETE)gnutoo/layer1-2015-wip

The goal is to touch the code as less as possible.

The following files still had to be modified:
* The Makefiles to integrate it into nuttx
* The layer1's main.c was converted to command-line only:
  No more keyboard and GUI handling.

TODO:
* Finish importing the layer1
* See how to avoid duplication with misc/tools/osmocon/ headers
* Makefile: use $(TOPDIR) if necessary instead of always using ../
  ../ could be used some time only
* Kconfig for -DCONFIG_* ?
* GTA02 support
