* Unify multiple HID interfaces into one

This reduces the number of USB endpoints required, which frees them up
for other things.

NKRO and EXTRAKEY always use the shared endpoint.

By default, MOUSEKEY also uses it. This means it won't work as a Boot
Procotol mouse in some BIOSes, etc. If you really think your
keyboard needs to work as a mouse in your BIOS, set
MOUSE_SHARED_EP = no in your rules.mk.

By default, the core keyboard does not use the shared endpoint, as not
all BIOSes are standards compliant and that's one place you don't want
to find out your keyboard doesn't work.. If you are really confident,
you can set KEYBOARD_SHARED_EP = yes to use the shared endpoint here
too.

* unify endpoints: ChibiOS protocol implementation

* fixup: missing #ifdef EXTRAKEY_ENABLEs

broke build on AVR with EXTRAKEY disabled

* endpoints: restore error when too many endpoints required

* lufa: wait up to 10ms to send keyboard input

This avoids packets being dropped when two reports are sent in quick
succession (eg. releasing a dual role key).

* endpoints: fix compile on ARM_ATSAM

* endpoint: ARM_ATSAM fixes

No longer use wrong or unexpected endpoint IDs

* endpoints: accommodate VUSB protocol

V-USB has its own, understandably simple ideas about the report formats.
It already blasts the mouse and extrakeys through one endpoint with
report IDs. We just stay out of its way.

* endpoints: document new endpoint configuration options

* endpoints: respect keyboard_report->mods in NKRO

The caller(s) of host_keyboard_send expect to be able to just drop
modifiers in the mods field and not worry about whether NKRO is in use.
This is a good thing. So we just shift it over if needs be.

* LED driver update addressing PR #3871

Update sync between IS31FL3733 drivers is causing varying behavior in keyboards including brightness mismatch and slight flicker at very low rgb values. Visually, disabling sync is not noticeable. Ref PR #3871 by guarnacciaa.

Appearenly, teensy controllers have some issues with waking up.  If the rgblight is called "too soon", it will cause the controller to lock up, intermittently. Adding a 10 ms
delay seems to fix this issue, as it lets it have enough time to handle things properly.

This has been tested extensively on my Ergodox EZ, and can be seen in the @drashna userspace, under the "suspend_wakeup_init_user" function.

Added support to enter bootloader from software (bootloader version must be newer than "v2.18Jun 22 2018 17:28:08" until workaround for older is created).
Updated CTRL and ALT keymaps for entering bootloader with Fn+b held for >500ms.
Added basic MacOS keymap for ALT.
USB sleep LED indicator now turns off after 1 second.
Slowed down debug LED code printing.

- Added support for NO_USB_STARTUP_CHECK. This allows the keyboard do function and not get stuck in a SUSPENDED state loop in case of no USB connection.
- Added support for WAIT_FOR_USB. In LUFA no keyboard has this flag enable therefor no keyboard waits for usb to be active.
- Added documentation for both configuration flags as they were missing.

This allows for macros to be assigned to press two mouse directions at same time, which allows for one key diagonals.

Renamed keyboard alt67 to alt and adjusted necessary files where alt67 appeared.
CTRL keymap fixed enum structure name.
usb2422 removed stray define no longer used.

MCU has 254 flash, changed 250 to 254. tested working on a planck rev6

- Renamed teensy EEPROM library and added conditional selection of library.
- Remapped EEPROM memory map for 16 byte blocks (as is with STM32f3xx MCUs).
