* Add  support to tap dances

* Move default tap code defines to header file

* Revert "Short term bodge for firmware size bloat (#14144)"

This reverts commit a8d6547346.

* Revert "Tidy up quantum.c now some of tmk_core has been merged (#14083)"

This reverts commit c4dbf4bf01.

* Migrate action|keyboard|keycode|eeconfig from tmk_core -> quantum

* Combo processing improvements.

Now it is possible to use ModTap and LayerTap keys as part of combos.
Overlapping combos also don't trigger all the combos, just exactly the
one that you press.

New settings:
- COMBO_MUST_HOLD_MODS
- COMBO_MOD_TERM
- COMBO_TERM_PER_COMBO
- COMBO_MUST_HOLD_PER_COMBO
- COMBO_STRICT_TIMER
- COMBO_NO_TIMER

* Remove the size flags from combo_t struct boolean members.

This in the end actually saves space as the members are accessed so many
times. The amount of operations needed to access the bits uses more
memory than setting the size saves.

* Fix `process_combo_key_release` not called correctly with tap-only combos

* Fix not passing a pointer when NO_ACTION_TAPPING is defined.

* Docs for `COMBO_ONLY_FROM_LAYER`

* Update docs/feature_combo.md

* Update quantum/process_keycode/process_combo.c

Co-authored-by: precondition <57645186+precondition@users.noreply.github.com>

* Add `EXTRA_SHORT_COMBOS` option.

Stuff combo's `disabled` and `active` flags into `state`. Possibly can
save some space.

* Add more examples and clarify things with dict management system.

- Simple examples now has a combo that has modifiers included.
- The slightly more advanced examples now are actually more advanced
  instead of just `tap_code16(<modded-keycode>)`.
- Added a note that `COMBO_ACTION`s are not needed anymore as you can
  just use custom keycodes.
- Added a note that the `g/keymap_combo.h` macros use the
  `process_combo_event` function and that it is not usable in one's
  keymap afterwards.

No need to call `dump_key_buffer` when disabling combos because the
buffer is either being dumped if a combo-key was pressed, or the buffer is empty
if a non-combo-key is pressed.

* Update ADC driver for STM32F1xx, STM32F3xx, STM32F4xx (#12403)

* Fix default ADC_RESOLUTION for ADCv3 (and ADCv4)

Recent ChibiOS update removed ADC_CFGR1_RES_10BIT from the ADCv3 headers
(that macro should not have been there, because ADCv3 has CFGR instead of
CFGR1).  Fix the default value for ADC_RESOLUTION to use ADC_CFGR_RES_10BITS
if it is defined (that name is used for ADCv3 and ADCv4).

* Update ADC docs to match the actually used resolution

ADC driver for ChibiOS actually uses the 10-bit resolution by default
(probably to match AVR); fix the documentation accordingly.  Also add
both ADC_CFGR_RES_10BITS and ADC_CFGR1_RES_10BIT constants (these names
differ according to the ADC implementation in the particular MCU).

* Fix pinToMux() for B12 and B13 on STM32F3xx

Testing on STM32F303CCT6 revealed that the ADC mux values for B12 and
B13 pins were wrong.

* Add support for all possible analog pins on STM32F1xx

Added ADC mux values for pins A0...A7, B0, B1, C0...C5 on STM32F1xx
(they are the same at least for STM32F103x8 and larger F103 devices, and
also F102, F105, F107 families).  Actually tested on STM32F103C8T6
(therefore pins C0...C5 were not tested).

Pins F6...F10, which are present on STM32F103x[C-G] in 144-pin packages,
cannot be supported at the moment, because those pins are connected only
to ADC3, but the ChibiOS ADC driver for STM32F1xx supports only ADC1.

* Add support for all possible analog pins on STM32F4xx

Added ADC mux values for pins A0...A7, B0, B1, C0...C5 and optionally
F3...F10 (if STM32_ADC_USE_ADC3 is enabled).  These mux values are
apparently the same for all F4xx devices, except some smaller devices may
not have ADC3.

Actually tested on STM32F401CCU6, STM32F401CEU6, STM32F411CEU6 (using
various WeAct “Blackpill” boards); only pins A0...A7, B0, B1 were tested.

Pins F3...F10 are inside `#if STM32_ADC_USE_ADC3` because some devices
which don't have ADC3 also don't have the GPIOF port, therefore the code
which refers to Fx pins does not compile.

* Fix STM32F3xx ADC mux table in documentation

The ADC driver documentation had some errors in the mux table for STM32F3xx.
Fix this table to match the datasheet and the actual code (mux settings for
B12 and B13 were also tested on a real STM32F303CCT6 chip).

* matrix: wait for row signal to go HIGH for every row (#12945)

I noticed this discrepancy (last row of the matrix treated differently than the
others) when optimizing the input latency of my keyboard controller, see also
https://michael.stapelberg.ch/posts/2021-05-08-keyboard-input-latency-qmk-kinesis/

Before this commit, when tuning the delays I noticed ghost key presses when
pressing the F2 key, which is on the last row of the keyboard matrix: the
dead_grave key, which is on the first row of the keyboard matrix, would be
incorrectly detected as pressed.

After this commit, all keyboard matrix rows are interpreted correctly.

I suspect that my setup is more susceptible to this nuance than others because I
use GPIO_INPUT_PIN_DELAY=0 and hence don’t have another delay that might mask
the problem.

* Add support for 8 buttons to mouse report

This includes support for 8 buttons in mousekeys.  However, this does move the keys around due to the fact that the last mousekey keycode is already 0xFF, so any past that would not work with register_code and the like, breaking them for tap hold keys, encoders, and other features.

With this change, when ps2_mouse is disabled, mousekeys works as usual. With
ps2_mouse enabled, mousekeys button state is shared with ps2_mouse for clicking,
dragging, and scrolling, mousekeys clicks are produced by ps2_mouse only, and
mouskeys button state is transferred to mousekeys without generating clicks to
enable mousekeys dragging.

This commits add the SH_OS keycode, which works similarly to one shot
layers:
* while pressed, the keyboard is swapped
* if no keys were pressed while it was pressed, the next key press is
swapped

SH_OS also supports chaining with one shot layers:
OSL(x) + SH_OS + key interprets the key press on the oneshot layer.

The ONESHOT_TIMEOUT setting used by one shot keys and layers is also
used by oneshot swap hands. In the above chaining scenario the timeout
of the oneshot layer is reset when swap hands is activated.

Resolves #2682

* Fix bug with layer caching in get_event_keycode

* Improve naming

* Improve process_record system

Code based on @colinta's

* Rename and better handle functions

* Fix incorrect function call to process_record_user

* Add documentation for post_process_record

* Add both get_event_keycode and get_record_keycode functions

And add some comments about these functions

* Update code format

* Cleanup merge artifacts

* Remove ACT_COMMAND

* And from action_t as well

* Fix extra keyboard report during test_fixture teardown

* Add tests for pressing two keys with only different modifers

* Fix #1708

When two keys that use the same keycode, but different modifiers were
pressed at the same time, the second keypress wasn't registered. This is
fixed by forcing a key release when we detect a new press for the same
keycode.

* Fix the NKRO version of is_key_pressed

* Fix uninitalized loop variable

* Compile error if ONESHOT_TIMEOUT defined but oneshot disabled

When ONESHOT_TIMEOUT and NO_ACTION_ONESHOT are both defined, this code
fails to compile.

Wrap the one usage of ONESHOT_TIMEOUT that is inconsistent with the
rest so all usages are properly wrapped by a check of NO_ACTION_ONESHOT.

* Run file through clang-format

* Run clang-format manually to fix recently changed files

* Run clang-format manually to fix recently changed files - revert template files

* Run clang-format manually to fix recently changed files - format off for ascii_to_keycode_lut

* Implement IGNORE_MOD_TAP_INTERRUPT_PER_KEY

- Add configurable option IGNORE_MOD_TAP_INTERRUPT_PER_KEY
- Add function get_ignore_mod_tap_interrupt iff the option is enabled

Unless IGNORE_MOD_TAP_INTERRUPT_PER_KEY is defined, this patch does not affect the resulting binary.

* Add documentation for IGNORE_MOD_TAP_INTERRUPT_PER_KEY

* Move tmk_core/common/backlight to quantum/backlight

* Add guards to backlight inclusion

* Add guards to backlight inclusion

* Update backlight guards on clueboard/60

* Use full paths to avoid vpath issues

* Fix bug in `do_code16()`

* Remove qk_ mods functions

* Extend allowed range of tappable keycodes to include modifiers

* Get rid of the magic numbers altogether

* Remove some more magic numbers

* Extract LM() functionality from ACT_LAYER_TAP

* Use ACTION() macro everywhere

* Add support for TAP_CODE_DELAY to Hold-Tap keys

* Better handling for tap code delay and caps version

* Make Caps Lock delay more reasonable

* Update documentation

* Update docs/config_options.md

* Typedef'ed layer_state_t to uint32_t.

This enables future work with layer_state_t to uint8_t for optimization purposes.

* Removed accidental xeal60 commit

* Revert to egyptian brackets, added sizeof(layer_state_t) so when layer_state_t is redefined it will automagically work.

* Add additional typedefs

* Add checks for setting layer state

* Update tmk_core/common/action_layer.h

* Revert commit.

* Increase delay for Hold-Tap register for CAPSLOCK

Because it seems that the 80ms delay wasn't too much

* Screw it, make the caps delay a define and make it configurable

* Keep pressed keys on layer state change

* Add doc comment for clear_keyboard_but_mods_and_keys

* Keep pressed keys only if PREVENT_STUCK_MODIFIERS is on

* Check STRICT_LAYER_RELEASE instead of PREVENT_STUCK_MODIFIERS

* Add delay in Tap Code to avoid issues

I think a few people have reporting issues with it working properly, and it may be a timing issue.  The 'register_code' uses this sort of delay in some of the functions, and
this is probably why.

Adding the 100ms delay should hopefully fix any issues with it.

* Make tap_code delay configurable

* Update documentation

* Bring tap_code16 inline with changes

* Fix type for tap_code16

Bad copy-paste job

* Just use the value check for the define

* Clarify timing in docs
