* Allow test framework to use cores/esp8266/Arduino.h directly * fix wps debugging * some more missing debug.h * Hunt down debug.h and roll-back TODO: rename it to something else... it is an internal header * Move abs+round checks to test/device/test_sw * Restore macros for C code * fixup! Move abs+round checks to test/device/test_sw * Fix bad c/p, actually try round with ints * tweak c macros per review * fix gcc-10 missing cerrno include
