Fix memory leaks by using stack instead of malloc
Reduce memory usage by having less temporary bufffers
Remove warnings by adding includes
Decrease code size by 608 bytes (mostly due to not linking malloc)
More robust handling of buffer overflows
Unlike the arduino functions, these don't take abstract pin numbers,
they take pin labels like `B0`. Also, rather than taking very
generic parameter names, these take slightly more descriptive
enum values.
These improve the clarity of code that would otherwise be inscrutable
bit manipulation in tersely named port register names.
Define a default TAPPING_TERM in quantum.c, for keyboards that do not
have it set. Fixes the CI failure.

When one holds a Space Cadet shift, to have it act as a shift, so that
mouse behaviour changes, when released without any other key pressed, it
still registers a paren. To remedy this, add a hold timeout: if the key
is held longer than TAPPING_TERM, it will not register the parens.
Fixes#884, with the side-effect of not being able to have parens
trigger the OS-side repeat anymore.

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 fixesalgernon/ergodox-layout#107.

There may be cases where one would like to know the current Unicode
input mode, without having to keep track of it themselves. Add a
function that does just this.

In order to not declare the same variable in multiple objects (which
happens when building UCIS-enabled keymap for both the ErgoDox EZ and
the ErgoDox Infinity), move the declaration to the .c file, and keep
only an extern reference in the header.
Many thanks to @fredizzimo for spotting the error in Travis, and
suggesting the fix.

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.

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.

Include `action_tapping.h`, so the keymap does not have to define a
`TAPPING_TERM` for us, and we can use the default.

When entering unicode codes, use some delay, so the OS has time to
process the information. This is not needed on all systems, but some
seem to require it.

It turns out that register_hex32 did not work reliably, and some systems
only allow 7 chars after the unicode magic sequence, while others allow
8. To remedy the situation, store the codes as strings, and type those
in instead of doing bit shifting magic.

If the symbol name being entered is longer than the max, stop recording
it, and stop processing keycodes apart from the ones that can delete,

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.

This moves the unicode input start / end sequences into their own
functions, so keymaps and other functionality can build on it too.
At the same time, it changes how the Linux variant works, to match
reality: CTRL+SHIFT must be unregistered too, and we close the thing
with a Space instead.

In the header, this was defined as `set_unicode_input_mode`, but the
implementation had `set_unicode_mode` for a name. Changed the
implementation to match the header.
