* suspend: suppress wake up keypress
Waking the host from suspend is done by pressing any key on the
keyboard, the regular key codes assigned to the keys are not important
and must not be sent - otherwise they usually end up in password prompts
as ghost characters that have to be deleted again. This commit adds
suppression for all keys pressed at the time of wake up. Once a key is
released it functions as a regular key again.

* suspend: update wake up matrix after wake up delay
If USB_SUSPEND_WAKEUP_DELAY is set, the keyboard sleeps during wake up -
which can be up to multiple seconds. To handle key presses and releases
in that time frame we have to handle the following cases:
1. Key not pressed before suspend, and not pressed after wakeup → do
nothing (normal case).
2. Key not pressed before suspend, but pressed after wakeup → set the
wakeup_matrix bit to 1 (so that the press and release events would be
suppressed).
3. Key pressed before suspend, but not pressed after wakeup → do nothing
(the release event will be generated on the first matrix_task() call
after the wakeup).
4. Key pressed before suspend, and still pressed after wakeup → do
nothing (the release event will be generated some time later).

* keyboards: anavi: macropad8: disable snake and rgb_test effects
...to shrink the binary size.
* feat: adds a transmit and receive i2c method
* fix: address the i2c transmit and receive length on u16
* Add AVR/LUFA implementation
Didn't add a progmem version, since that would only apply to receive.
Figured it wasn't worth it, but can add.
* Rearrange order of functions
* Add docs
* Fix doc gen error
* Fix lint issues
* fix more lint issues
A small refactoring of the defines TIMER_DIFF_8, TIMER_DIFF_16, TIMER_DIFF_32, TIMER_DIFF_RAW.
Removing obsolete TIMER_DIFF helper.
