Use function for KEYCODE2 routines instead of macro. (#8101)
* Option to use function for KEYCODE2 routines.

Convert the KEYCODE2SYSTEM and KEYCODE2CONSUMER macros to functions,
defaulting to using the macros.  The function form allows the compiler
to optimize the switch statement itself, over the macro nested
ternaries.

To enable this feature, #define USE_KEYCODE2_FUNCTION.

Testing against a random selection of avr-based keyboards, this
increased available flash by ~500 bytes. For arm-based keyboards,
the available flash increased by ~400 bytes.

* Replace macro with function entirely.

As zvecr states, go bold and just commit to using the function instead
of the macro.

* Reformat whitespace now that functional review is done

Verified against clang-format output.

TMK Keyboard Firmware Core Library

This is a keyboard firmware library with some useful features for Atmel AVR and Cortex-M.

Source code is available here: https://github.com/tmk/tmk_keyboard/tree/master/tmk_core

Updates

2016/02/10

flabbergast's Chibios protocol was merged from https://github.com/flabbergast/tmk_keyboard/tree/chibios. See protocol/chibios/README.md. Chibios protocol supports Cortex-M such as STM32 and Kinetis.

Debugging

Use PJRC's hid_listen to see debug messages. You can use the tool for debug even if firmware use LUFA stack.

You can use xprintf() to display debug info on hid_listen, see common/xprintf.h.
