HAL compatible pinsDebug & misc

Re-ARM has been tested.  AVR has not been tested.

1) moved all cpu specific items to files in the low level HAL directory
for that CPU (pinDebug_Re-ARM.h & pinsDebug_AVR_8_bit.h

2) added pinsDebug.h to the top level directory

3) modified HAL_pinsDebug.h to select the correct support file for the
selected CPU

4) Patched sanitycheck to stop throwing false errors.  A long term
solution will be done

5) misc changes & bug fixes
arduino.cpp - included macros.h to fix a missing definition
pinmap_re-arm.h - removed a duplicated line.
pinmapping.h - changed from "ENABLED" to "defined" to fix a compile
error

======================================================================

split SanityCheck up, improve pinsDebug system

======================================================================

switch to latest pins_RAMPS_RE_ARM.h
