Gergely Nagy 38f204db30 Allow one-shot modifiers to be chained
Many a times one would want to use multiple modifiers with the same key,
preferably without having to hold anything, like `Ctrl+Shift+C` or
`Ctrl+Shift+V` to copy/paste in GNOME Terminal. To make this possible, we need
to be able to chain one-shot modifiers, so that we can have multiple of them
active at the same time.

The easiest way to accomplish this is that whenever we activate a one-shot
modifier, we apply it on top of the existing set, instead of re-setting the
state. When deactivating, either due to an interrupt, or due to a timeout, we
deactivate all oneshots anyway, so the clearing part is covered. When we turn
the one-shot modifier into a toggle, that will also clear all one-shot modifiers
first, so we covered that case too.

Fixes #2796, #1580, and #856.

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.
