* Incorporates patches and changes to HID reporting

There are some patches provided by @a-chol incorporated on this commit,
and also some changes I made to the HID Report structure.

The most interesting is the one dealing with number of buttons: Linux
doesn't seem to care, but Windows requires the HID structure to be byte
aligned (that's in the spec). So if one declares 8/16/32... buttons they
should not have any issues, but this is what happens when you have 9
buttons:

```
 bits |0|1|2|3|4|5|6|7|
      |*|*|*|*|*|*|*|*| axis 0 (report size 8)
      |*|*|*|*|*|*|*|*| ...
      |*|*|*|*|*|*|*|*|
      |*|*|*|*|*|*|*|*|
      |*|*|*|*|*|*|*|*|
      |*|*|*|*|*|*|*|*|
      |*|*|*|*|*|*|*|*| axis 6
      |*|*|*|*|*|*|*|*| first 8 buttons (report size 1)
      |*| | | | | | | | last of 9 buttons, not aligned
```

So for that I added a conditonal that will add a number of reports with
size 1 to make sure it aligns to the next multiple of 8. Those reports
send dummy inputs that don't do anything aside from aligning the data.

Tested on Linux, Windows 10 and Street Fighter (where the joystick is
recognized as direct-input)

* Add save and restore of each pin used in reading joystick (AVR).
Allow output pin to be JS_VIRTUAL_AXIS if the axis is connected to Vcc
instead of an output pin from the MCU.

Fix joystick report id

Fix broken v-usb hid joystick interface. Make it more resilient to unusual settings (none multiple of eight button count, 0 buttons or 0 axes)

Correct adc reading for multiple axes. Piecewise range conversion for uncentered raw value range. Input, output and ground pin configuration per axis.

* Reduce PROGMEM usage for keycode map

Bit-pack the keycode bool array to gain back a small amount of flash space.
The trade-off is an increase in runtime instructions when running macros.

It does make the code a bit harder to read, as well as maintain.

For configs that use send_string() et al, it saves ~100 bytes.

* Switch to macro and common definition

Rewrite the array declarations so both the unpacked (original) and
packed LUT arrays can use the same value definitions. This is done by
defining a macro that "knows what to do".

This makes the code much easier to read and maintain.

* Fix macro typos and improve perf

Pack the bits in a more efficient order for extraction.
And also fix the copy/paste error in the macro...

* Switch fully to packed LUT

Some minor reformatting.
Compile tested all sendstring_xyz.h to make sure they were converted
properly. Also checked that an unconverted version would generate a
compile error.

Also, it adds user hooks to the feature so users can customize the existing functionality.

With my XD60, I noticed that when typing the backlight was flickering.

The XD60 doesn't have the backlight wired to a hardware PWM pin.
I assumed it was a timing issue in the matrix scan that made the PWM
lit the LED a bit too longer. I verified it because the more keys that
were pressed, the more lighting I observed.

This patch makes the software PWM be called during CPU interruptions.
It works almost like the hardware PWM, except instead of using
the CPU waveform generation, the CPU will fire interruption
when the LEDs need be turned on or off.

Using the same timer system as for hardware PWM, when the counter
will reach OCRxx (the current backlight level), an Output Compare
match interrupt will be fired and we'll turn the LEDs off.
When the counter reaches its maximum value, an overflow interrupt
will be triggered in which we turn the LEDs on.
This way we replicate the hardware backlight PWM duty cycle.

This gives a better time stability of the PWM computation than pure
software PWM, leading to a flicker free backlight.

Since this is reusing the hardware PWM code, software PWM also supports
backlight breathing.

Note that if timer1 is used for audio, backlight will use timer3, and if
timer3 is used for audio backlight will use timer1.
If both timers are used for audio, then this feature is disabled and we
revert to the matrix scan based PWM computation.

* Update documentation to be at least vaguely accurate

* Use `get_tapping_term(tapping_key.event)` instead

`e` doesn't include column and row information, properly. It registers as 255, regardless of the actual keypress.

However `tapping_key.event` actually gives the correct column and row information.  It appears be the correct structure to use. 

In fact, it looks like the issue is that `e` is actually the "TICK" structure, as defined in keyboard.h

* Use variable tapping term value rather than define

* Silly drashna - tapping_key.event, not event

* add get_event_keycode() function

* Fix typo

* Remove post_process_record_quantum since it's the wrong PR

* Update quantum/quantum.c

* Better handle ifdef statement for permissive hold

Since we can't be sure that tapping term is actually 500

* Update quantum.c comments based on feedback

* Clean up get_tapping_term function

Clean up function so that users don't need to call the event function, and instead only check the keycode

* Add ability to run functionality on and off

* Make ifdef's more compact

* Update split_common to use standard i2c drivers

* Eliminate RGB_DIRTY/BACKLIT_DIRTY

* Fix avr i2c_master error handling

* Fix i2c_slave addressing

* Remove unneeded timeout on i2c_stop()

* Fix RGB I2C transfers

* Remove incorrect comment

* initial work to add eeprom to haptic feedback and decouple the feedback process from keyboards

* Haptic feedback enhancements: on/off toggle working, feedback order working
todo:
-work on modes switching
-get modes switching to save to eeprom

* haptic enhancement - eeprom and modes added

* Added set and get functions for haptic feedback

* initial implementation of solenoids under haptic feedback

* changed eeprom to 32 bits to reserve blocks for future features

* start documentation of haptic feedback

* change keycode per comment from reviewers

* typo fixes

* added eeprom for solenoid configs

* added solenoid and docs

* Add/fix default parameters configs, improve docs

* more doc cleanup

* add in solenoid buzz toggle, clean up doc

* some fixes for error in compiling solenoid

* fix a chibios specific i2c read function and added one for AVR controllers in DRV2605L.c

* fixes for avr side issues

* update keymap

* fix keymap compile error

* fix bugs found during solenoid testing

* set pin that is not powered during bootloader

* added warning about certain pins on the MCU may trip solenoid during DFU/bootloader

I think `quantum.h` should contain only API declarations that `quantum.c` provides externally. `rgb.h` contains function weak definitions. This should not be in `quantum.h`.
