Changes:

• add support for the iot-lab_M3
• temporarily drop support for TelosB (will return in a separated PR)
• split patch.txt into one patch file for each original file

• includes remaining findings and improvements from the 6TiSCH plugtest

Depends on:

• stm32f103_rey6: implement std periph driver OlegHahm/thirdparty_cpu#26
• stm32f103rey6: backported RTC_GetAlarm function in st stdlib  OlegHahm/thirdparty_cpu#30

Duuuude!!

How can anyone but you keep this pkg up to date in the future?

[thomaseichinger]

😄 as you see, already reduced changed lines to half.
Further reductions are in the pipeline (eliminating HW specific dependencies) but wont make it into this release.
Most changes are dedicated to the fact that OpenWSN throws lots of warnings with our compiler flags and compiles now warning free. Hope to get most of those into OpenWSN upstream though.

updated addressing @LudwigOrtmann's in person comment to remove $(BOARDINCLUDE) $(PROJECTINCLUDE) $(CPUINCLUDE) from Makefiles

[OlegHahm]

Shouldn't the first two commits be squashed? (Since they won't work separately.)

[thomaseichinger]

yes, they will be squashed but wanted to provide the possibility to review without the patch files obfuscating all the other changes.

[OlegHahm]

I see. In this case: ACK, squash, and merge at will.

[thomaseichinger]

squashed and GO
