Slightly optimized all Makefiles
ChibiOS updated to version stable_19.1.x.NOTE: ChibiOS 19.1.x seems to contain some issues as of now.
All preprocessor directives without arguments (e.g. #endif) are now followed by a comment, indicating where it belongs to (e.g. the preceding #if).
Applied AMiRo-OS header to sime files, which still held the ChibiOS header.
DW1000 unit test updated
Merge branch 'master' of http://openresearch.cit-ec.de/git/amiro-os.amiro-os
Added DW1000 demo app on top of NUCLEO_F103RB example
Enhanced the periphAL debug implementation to apply to tze new AMiRo-OS debug API
set the C standard to C17 (ISO), although this does not make any difference according to GCC documentation
Introduced the CORTEX_ENABLE_WFI_IDLE flag in all chconf.h files, so the MCUs will enter sleep mode whenever the system is idle.
Enhanced and fixed several module specific files.
Changed all header guards so they will not use unserscores as pre- and postfix.
Introduced support the STM32F103 NUCLEO module.
