`updateActiveLayers()` makes it impossible to turn off the default
layer, so there's no point searching past it for the highest layer,
and `defaultLayer` can be set to numbers higher than zero.
Now that `layer_count` is (potentially) available, we can start
looking for active layers at the top _defined_ layer instead of the
top _possible_ layer. This ought to be more efficient, especially for
sketches that don't have lots of layers defined.
Also introduced the `MAX_LAYERS` constant (#define).
Instead of sending a press & release for the consumer key when the physical key
is released, send a press each cycle it is held, a report along with the
keyboard report, and clear the consumer report each cycle too.
This will prevent these keys getting stuck, or sending multiple presses in the
same report.
Fixes#176.

If we call updateLiveCompositeKeymap() on key release the keymap gets
updated before the release event occurs, and any ShiftToLayer(N) key
with a different definition on layer N won't work properly. Before its
release event is processed, it gets updated to the new value, and
layer N doesn't get turned off. If we only update the live keymap on
key press events, we don't have this problem.
replacing the Key_16bit macro with CONSUMER_KEY macro allowed us to
add the IS_CONSUMER and SYNTHETIC flags within the CONSUMER_KEY macro
and simplify the Consumer key definitions.
If it's an old sketch, LayerCount will default to 0, so in order for
Layer.on() to function, don't bother checking for out-of-bounds if
LayerCount == 0.
Declaring LayerCount as a weak symbol in layers.cpp lets us override
it if the CREATE_KEYMAP macro is used to define the keymap in the
sketch file, but still allows old sketch files to compile without
errors.
Still some changes necessary to allow old sketches to work
properly (Layer.on() will abort before doing anything).
This macro allows the definition of the LayerCount variable and the
keymaps[] array together. It shouldn't break old sketches, but this is
probably not all that's necessary; LayerCount still doesn't get
initialized outside the macro.
Update key_events.cpp (IS_INTERNAL Handling)
I'm merging this for now, even though I know it's not the 'right' solution. But I'd like Mute to work correctly for MP2 keyboards and we're on deadline
This file is meant to be included in sketch files in order to make
data available to Kaleidoscope functions. In particular, the size of
the keymaps[] array (i.e. the number of defined layers), which is
needed in order to prevent reading uninitialized memory past the end
of that array due to Key_KeymapNext_Momentary.
By moving the IS_CONSUMER flag to B00001000 instead of
B00000010 (swap with IS_INTERNAL) we can detect the if the key is a
consumer key and strip out the flags and use the full 10bit to send to
the hid report. This enable us to use all the Consumer_* keys
Reordered if chain in handleSyntheticKeyswitchEvent to fix a bug preventing some Consumer and System Control HID functions from being sent due to bit overload/collision with the IS_INTERNAL flag.
Make Kaleidoscope_ a friend class, so that it can access .begin. The
reason behind this is that .begin is an interface towards
Kaleidoscope.use(), and that function should be the only user. To
discourage its use, make it protected.
This does not break any existing - and valid - code, but allows us to
slowly migrate the plugins to a protected begin() method.
Fixes#177.
As discussed in #196, if we are making `KaleidoscopePlugin.begin` protected, we
might as well give it a better name. That name is `initialSetup`, and this
change is the first step towards the migration. It introduces `initialSetup`
which will call `begin` for now, and deprecate `begin`, which is no longer an
abstract function.
Once everyone migrated to the new name, we can remove `.begin`, and turn
`.initialSetup` into an abstract function.

`Kaleidoscope.use` is a much better interface, therefore deprecate USE_PLUGINS.
We do this by creating a wrapper function, `__USE_PLUGINS` that will call
`Kaleidoscope.use` under the hood, but has a deprecated attribute attached. We
then make the `USE_PLUGINS` macro call this function.
We do this because we want to make sure that the list is NULL-terminated, and
for that, we need the macro.

This was only ever used for `Kaleidoscope.setup()`, and while the variant that
takes an argument is deprecated, and emits a warning already, we can do the same
for `KEYMAP_SIZE` too.
This does set the const to 0, so if used anywhere else than
`Kaleidoscope.setup()`, it will have undesired side-effects. But as far as I
saw, it was never used elsewhere, thus, this change should be safe.

For all cases outside of Kaleidoscope itself, we are good with the value of

upon @obra's suggestion - rename `Layer.highest()` to `Layer.top()`, and the old
`Layer.top()` to `Layer.updateHighestLayer()`, and make the latter private, and
update the `highestLayer` member variable instead of returning the number.

Sometimes we would like to know the highest active layer, which is available in
the `highestLayer` private variable, and via `.top()` too. We do not want to
make `highestLayer` public, because we want to be the only ones changing it. And
while `top()` gets us roughly the same information, it does so at a cost. For a
lot of purposes, the cached `highestLayer` would be perfectly adequate.
The new `Layer.highest()` accessor does just this.

Refactor the momentary layer handling part of `handleKeymapKeyswitchEvent`.

based on the target layer, and branch out depending on `keyState` from there.

If we have two keys on our keymap that momentarily go to the same layer (which
is the case for the factory firmware), we hold both, and release one, we want
the layer to remain active still.
To this effect, in `handleKeymapKeyswitchEvent` we will handle the case when a
momentary layer key is pressed, but not toggled on (that is, it is held): if it
is not a next/previous switch, we re-activate the layer if it wasn't on.
This fixes#154, thanks to @ToyKeeper for the report.

With the new implementation, there are two lookup functions, because we have two
caches, and different parts of the firmware will want to use either this or
that (or perhaps both, in rare cases).
First of all, we use caches because looking up a key through all the layers
is costy, and the cost increases dramatically the more layers we have.
Then, we have the `effectiveKeymapCache`, because to have layer behaviours
we want, that is, if you hold a key on a layer, release the layer key but
continue holding the other, we want for the layered keycode to continue
repeating. At the same time, we want other keys to not be affected by the
now-turned-off layer. So we update the keycode in the cache on-demand, when
the key is pressed or released. (see the top of `handleKeyswitchEvent`).
On the other hand, we also have plugins that scan the whole keymap, and do
things based on that information, such as highlighting keys that changed
between layers. These need to be able to look at a state of where the
keymap *should* be, not necessarily where it is. The `effectiveKeymapCache`
is not useful here. So we use a `keymapCache` which we update whenever
layers change (see `Layer.on` and `Layer.off`), and it updates the cache to
show how the keymap should look, without the `effectiveKeymapCache`-induced
behaviour.
Thus, if we are curious about what a given key will do, use `lookup`. If we
are curious what the active layer state describes the key as, use
`lookupUncached`.

Only update the keymap cache if the layer state changed for real. If we turn a
layer that was already on, on again, we do not need to update. Same for turning
them off.
This results in a tiny speedup if we have code that calls `Layer.on()` or
`Layer.off()` often.

When we change layers, we want to update the key cache for the whole keyboard,
so that LED modes and other things that depend on all keys being up-to-date will
work as expected.
Do the same at `Kaleidoscope.setup` time, so we start with a good state too.

Instead of storing the layer for each key, store the keycode, so that lookups
are considerably faster (one array lookup instead of two). This saves us almost
a full millisecond per scan cycle. Furthermore, inline `Layer_.lookup`, saving
us even more time.
Signed-off-by: Gergely Nagy <algernon@madhouse-project.org>
This changes how key caching & lookup works: instead of updating the whole key
cache whenever we change the layer state, we update each key before they are
pressed or released. This allows us to have two different ways in which layers
can work:
- Keys still held when releasing the layer key will be masked out until they are
released. (This is the current behaviour)
- Keys held will repeat the keycode they had when they toggled on, even if the
layer key gets released prior to this other key, while other keys will not be
affected.
One can toggle between the two modes by setting
`Kaleidoscope.repeat_first_press` to `true` (second behaviour) or `false` (first
behaviour).
For now, the default behaviour is left unchanged.

The goal is to ignore key events from still-held keys in a situation where we
just turned a layer off. Thus, if one holds a momentary layer key, then presses
and holds another key, releases the layer key, we want to ignore the other held
keys until they are released.
This is accomplished by masking all held keys when a momentary layer has been
turned off, and ignoring all masked key events in `handleKeyswitchEvent` until
they are released, when we unmask them.
This should address #150, but requires
