Gergely Nagy acda2b793f tap-dance: Do not start a sequence on keyup
There was an odd case, which confused the hell out of tap-dance: suppose
you had a number of tap-dance keys, on a layer, and as part of the
tap-dance, you turned that layer off - or had it on one-shot to begin
with. In this case, the keydown event would trigger the tap-dance key,
but the keyup would not. This had two funky consequences:

- tap-dance did not correctly register that the dance has ended.
- pressing any other tap-dance key would interrupt the previous
  tap-dance, and potentially input unwanted characters.

To fix this, we simply do not start a tap-dance sequence on keyup, only
when it is pressed. This way the previous sequence has enough time to
time-out and finish properly, and we don't get confused.

This fixes algernon/ergodox-layout#107.

Gergely Nagy 0d28787c5c Add a register/unregister_code16 pair of functions
These functions register not only the 8bit keycode, but the modifiers
too. It doesn't handle the full range of the upper 8bits, just the mods,
but that's a good start.

Changed the tap-dance pair functions to use these, so one can do:

  `ACTION_TAP_DANCE_DOUBLE (KC_COLN, KC_SCLN)`

...and that will do the right thing.

Gergely Nagy 29f64d7a93 tap-dance: Major rework, to make it more reliable
This reworks how the tap-dance feature works: instead of one global
state, we have a state for each tap-dance key, so we can cancel them
when another tap-dance key is in flight. This fixes #527.

Since we have a state for each key, we can avoid situation where a keyup
would mess with our global state. This fixes #563.

And while here, we also make sure to fire events only once, and this
fixes #574.

There is one breaking change, though: tap-dance debugging support was
removed, because dumping the whole state would increase the firmware
size too much. Any keymap that made use of this, will have to be
updated (but there's no such keymap in the repo).

Also, there's a nice trick used in this rework: we need to iterate
through tap_dance_actions in a few places, to check for timeouts, and so
on. For this, we'd need to know the size of the array. We can't discover
that at compile-time, because tap-dance gets compiled separately. We'd
like to avoid having to terminate the list with a sentinel value,
because that would require updates to all keymaps that use the feature.
So, we keep track of the highest tap-dance code seen so far, and iterate
until that index.

Gergely Nagy fa06a16360 process_unicode: Add a way to enter unicode symbols by name
The purpose of this change is to allow keymaps to specify a dictionary
of unicode symbol name to code mappings, and let the person at the
keyboard enter unicode symbols by name.

This is done by having a way to trigger unicode symbol input mode, when
all keys are cached until Esc, Enter or Space are pressed. Once that
happens, we try to look up the symbol from our lookup table. If found,
we erase back, and type the unicode magic in to get that symbol. If not
found, we still erase back, start unicode input mode, and replay what
the user typed in.

With this change, tap dance will now store the pressed state of the

The registration must happen in the `on_dance_finished` callback, while
unregistering goes to `on_reset`. The surrounding code makes sure not to
call either multiple times.

* quantum: Add a tap dance feature (#451)

* quantum: Add a tap dance feature

With this feature one can specify keys that behave differently, based on
the amount of times they have been tapped, and when interrupted, they
get handled before the interrupter.

To make it clear how this is different from `ACTION_FUNCTION_TAP`, lets
explore a certain setup! We want one key to send `Space` on single tap,
but `Enter` on double-tap.

With `ACTION_FUNCTION_TAP`, it is quite a rain-dance to set this up, and
has the problem that when the sequence is interrupted, the interrupting
key will be send first. Thus, `SPC a` will result in `a SPC` being sent,
if they are typed within `TAPPING_TERM`. With the tap dance feature,
that'll come out as `SPC a`, correctly.

The implementation hooks into two parts of the system, to achieve this:
into `process_record_quantum()`, and the matrix scan. We need the latter
to be able to time out a tap sequence even when a key is not being
pressed, so `SPC` alone will time out and register after `TAPPING_TERM`
time.

But lets start with how to use it, first!

First, you will need `TAP_DANCE_ENABLE=yes` in your `Makefile`, because
the feature is disabled by default. This adds a little less than 1k to
the firmware size. Next, you will want to define some tap-dance keys,
which is easiest to do with the `TD()` macro, that - similar to `F()`,
takes a number, which will later be used as an index into the
`tap_dance_actions` array.

This array specifies what actions shall be taken when a tap-dance key is
in action. Currently, there are two possible options:

* `ACTION_TAP_DANCE_DOUBLE(kc1, kc2)`: Sends the `kc1` keycode when
  tapped once, `kc2` otherwise.
* `ACTION_TAP_DANCE_FN(fn)`: Calls the specified function - defined in
  the user keymap - with the current state of the tap-dance action.

The first option is enough for a lot of cases, that just want dual
roles. For example, `ACTION_TAP_DANCE(KC_SPC, KC_ENT)` will result in
`Space` being sent on single-tap, `Enter` otherwise.

And that's the bulk of it!

Do note, however, that this implementation does have some consequences:
keys do not register until either they reach the tapping ceiling, or
they time out. This means that if you hold the key, nothing happens, no
repeat, no nothing. It is possible to detect held state, and register an
action then too, but that's not implemented yet. Keys also unregister
immediately after being registered, so you can't even hold the second
tap. This is intentional, to be consistent.

And now, on to the explanation of how it works!

The main entry point is `process_tap_dance()`, called from
`process_record_quantum()`, which is run for every keypress, and our
handler gets to run early. This function checks whether the key pressed
is a tap-dance key. If it is not, and a tap-dance was in action, we
handle that first, and enqueue the newly pressed key. If it is a
tap-dance key, then we check if it is the same as the already active
one (if there's one active, that is). If it is not, we fire off the old
one first, then register the new one. If it was the same, we increment
the counter and the timer.

This means that you have `TAPPING_TERM` time to tap the key again, you
do not have to input all the taps within that timeframe. This allows for
longer tap counts, with minimal impact on responsiveness.

Our next stop is `matrix_scan_tap_dance()`. This handles the timeout of
tap-dance keys.

For the sake of flexibility, tap-dance actions can be either a pair of
keycodes, or a user function. The latter allows one to handle higher tap
counts, or do extra things, like blink the LEDs, fiddle with the
backlighting, and so on. This is accomplished by using an union, and
some clever macros.

In the end, lets see a full example!

```c
enum {
 CT_SE = 0,
 CT_CLN,
 CT_EGG
};

/* Have the above three on the keymap, TD(CT_SE), etc... */

void dance_cln (qk_tap_dance_state_t *state) {
  if (state->count == 1) {
    register_code (KC_RSFT);
    register_code (KC_SCLN);
    unregister_code (KC_SCLN);
    unregister_code (KC_RSFT);
  } else {
    register_code (KC_SCLN);
    unregister_code (KC_SCLN);
    reset_tap_dance (state);
  }
}

void dance_egg (qk_tap_dance_state_t *state) {
  if (state->count >= 100) {
    SEND_STRING ("Safety dance!");
    reset_tap_dance (state);
  }
}

const qk_tap_dance_action_t tap_dance_actions[] = {
  [CT_SE]  = ACTION_TAP_DANCE_DOUBLE (KC_SPC, KC_ENT)
 ,[CT_CLN] = ACTION_TAP_DANCE_FN (dance_cln)
 ,[CT_EGG] = ACTION_TAP_DANCE_FN (dance_egg)
};
```

This addresses #426.

To be consistent with how the rest of the quantum features are
implemented, use ifdefs instead of dummy functions.
