conflict between stdbool.h and wiring.h

[Bill Greiman]

I forgot to mention this small problem in the previous post about ChibiOS/RT.

There is a define conflict in wiring.h that causes warnings when compiling C files that include stdbool.h before wiring.h

See the attached program.

This is from a compile for Teensy 3.6.

Sketch uses 20680 bytes (1%) of program storage space. Maximum is 1048576 bytes.
Global variables use 3968 bytes (1%) of dynamic memory, leaving 258176 bytes for local variables. Maximum is 262144 bytes.

I am making good progress on the ChibiOS port. I have AVR, Teensy 3.xx, and Arduino Zero working with a single library.
