Key masking was a bandaid, and we have better ways to achieve the same thing
now. All current users have been switched over to different methods now, so lets
deprecate the masking.
We only put the `DEPRECATED` label on the `maskKey` method, because the rest are
used internally too, and we do not want to emit warnings for those.

This adds `LEDControl.disable()` and `LEDControl.enable()` which disable and
enable LED operations, respectively. These are meant to replace the current
`LEDControl.paused` property (which is getting deprecated with this change), and
do some additional work on top of just disabling or re-enabling future updates
and sync. Namely, `disable()` will also turn LEDs off, while `enable()` will
refresh them all, too.
We also add a dedicated `Key_LEDToggle` key to disable/enable LEDs. This is
useful when one wants to turn LEDs off, without changing active LED mode to
`LEDOff`.

With this change, each device can specify a short name in their device
properties, which will be used to override the HID shortname. Due to link order,
we need to do the override in the user sketch, so we hook into the `KEYMAPS`
macro, to call `_INIT_HID_GETSHORTNAME`, which will set the override up for us.
The short name defaults to "kaleidoscope".

Unions are a C-reminiscense that are better avoided in modern C++.
They cause specific problems due to their nature of representing
independent types. The way they are used in Kaleidoscope, they
can easily be replaced by a class.
This enables it to properly work with Key objects in constexpr context
where with the old union-based implementation the compiler reported
errors when one Key was constructed based on a key_code/flags pair and
another one through raw-data. In such a case, the compiler assumes that
both Key instances represent something entirely different. This is
because unions were never meant for type conversions and the C++
standard considers their use for that purpose as undefined behavior.
The new class provides accessor methods for raw-data access and for
key_code/flags-data access.
This is a breaking change as it is is not possible to replace direct
member access patterns like
key.raw = 0xFFFF;
based on the raw-accessors.
For the .keyCode and .flags members, proxy objects are used
to enable the generation of suitable deprecations warnings.
All direct access via .raw, .keyCode and .flags have been replaced
throughout Kaleidoscope.

The new device APIs were built on top of composition (instead of inheritance,
like the former one). At the highest level, we have `kaleidoscope::device::Base`
and `kaleidoscope::device::BaseProps`. The latter is a set of overrideable
properties, components that make up the device: the key scanner, LEDs, MCU, and
so on.
Many components - like the key scanner and LEDs - also come in a similar setup:
the base class and properties, because this allows us to make them fairly
efficient templates.
All of the existing devices have been ported to the new APIs. While the old
`Hardware` base class remains - for now, and deprecated - it is not guaranteed
to work.

Instead of having to define `HARDWARE_IMPLEMENTATION` to the class name of the
device, and define `KeyboardHardware` from within the plugin, let all devices
set `kaleidoscope::Device` to their own class via a typedef. Furthermore,
instead of `KeyboardHardware`, use `Kaleidoscope.device()` instead. This makes
device plugins a little bit simpler, and our naming more consistent.
Because some parts of the firmware need to access the device object before the
`Kaleidoscope` object is available, we can't make it a member of that. For this
reason, the device object is `kaleidoscope_internal::device`, and
`Kaleidoscope.device()` wraps it. In general, the wrapper should be used. But if
access to the device is required before `Kaleidoscope` is available, then that's
also available.
The `Kaleidoscope` object grew a few more wrappers: `storage()` and
`serialPort()`, so that one doesn't need to use `Kaleidoscope.device()`
directly, but can use the wrappers, which are noticably shorter to write.

This PR introduces the concept of dynamic LED modes. Those are LED modes whose class instances
have a restricted lifetime that lasts only as long as a LED mode is active. By this means
it is possible to support a greater amount of LED modes - especially RAM-hungry ones - in the same firmware build. The amount of RAM used to store dynamic LED modes is now bounded
by the maximum size (`sizeof(...)`) of the largest dynamic LED mode.
Old-style LED modes are furtheron called _static_ in the terminology of this PR. They are still supported and blend in nicely with the newly introduced dynamic LED modes.
All changes are entirely backward compatible. No user sketches or existing user plugins require changes.
The greatest benefit of this change is that it drastically reduces the consumption of RAM
when multiple complex LED modes are used. Currently the most complex stock LED mode is
the wavepool effect. Its plugin requires around 140 bytes of RAM that are statically allocated and cannot be shared with any other features.
With this change it becomes possible to have a large number of such resource-hungry LED modes in parallel without a significant gain in RAM consumption.
For the stock firmware this change means a small (~30 byte) growth in terms of PROGMEM. On the other hand it reduces the amount of statically consumed RAM by ~90 bytes. As the current atmel architectures come with around ten times as much PROGMEM as RAM, this means a great improvement as RAM is the more critical resource.
If the wavepool effect, a especially RAM-hungry LED mode is added to the stock firmware,
the saving of RAM increases to 160 bytes which is almost 8% of RAM of the Keyboardio Model01.
A new interface class `LEDModeInterface` was introduced that those plugins
that export dynamic LED modes inherit from. To remain backward compatible, the `LEDMode` class that all pre-existing LED mode plugins inherited from is also derived from `LEDModeInterface`.
The new interface class currently lives in header `LEDMode.h` (see information about this new header below). This is because `LEDMode` and `LEDModeInterface` will
always be used together by dynamic LED modes. Thus, an extra header for `LEDModeInterface` would only mean extra include work for users writing plugins.
Those plugins that export dynamic LED modes must furtheron provide a exported type `DynamicLEDMode`.
This can either be done by defining a nested class of that name or by typedef-ing a class that is defined at global scope to `DynamicLEDMode`. See the modified stock LED modes for examples.
Some of those plugins that export dynamic led modes require access to their particular
dynamic LED mode. By adding the macro `ACCESS_THIS_LED_MODE` to the plugin class definition,
additional data and methods (an integer `led_mode_id_) are synthesized, that enable the plugin class to gain access to their particular dynamic LED mode instance (as long as it is active).
The synthesized integer member `led_mode_id_` can be used to query if the currently active LED mode is the oned handled by the plugin class instance (note that there might be more than one plugin instance of the same class and thus also several dynamic LED modes, see e.g. the solid color LED mode).
A query in the plugin's event handler e.g. looks as follows.
```cpp
if (::LEDControl.get_mode_index() != led_mode_id_)
return EventHandlerResult::OK;
```
All stock LED modes have been adapted to export dynamic LED modes (if possible).
This does not apply to all of them as for some the transition would have provided no gain.
It would even have meant a deterioration of resource consumption for those few pre-existing stock LED mode plugins that hardly have no (static) data-members at all (like e.g. `LEDOff`).
To reduce the amount of compile unit and header interdependencies, the class `LEDMode` has been moved to a header/implementation file of its own.
The `LEDControl` class now does not have a static array anymore to store LED mode pointers.
Instead, it delegates the core LED mode handling to a newly introduced `LEDModeManager` class
that lives in internal namespace. The `LEDModeManager` class is there to restrict access
to LED modes but also to wrap up core LED mode handling. If this functionality would
have been added to class `LEDControl`, far too much of the internals of LED mode handling would have been exposed to users through header `LEDControl.h`.
The new internal header `array_like_storage.h` contains a template class that is used to generate
array-like storages. Here array-like means that the contained pieces of information
are stored contiguously in memory in the same way as they would be when defining
language intrinsic (C-style) arrays. This type of storage is especially useful to generate array-like data struktures
in PROGMEM at compile time based on a list of global objects or POD data. By casting the array-like storage's address
to the content's pointer type, an array-like indexed access is possible.
In this PR an array-like data structure is used to generate a PROGMEM
array of LED mode factories. Array-like data structures could also become useful in other places and for future applications.
The most complex part of the implementation of the new LED mode handling is wrapped up in
`LEDModeManager.h` and `LEDModeManager.cpp` to hide it from users' site.
There, recursive template classes are used to setup an array-like data structure of `LEDModeFactory` instances in PROGMEM. Each of the stored `LEDModeFactory`s are associated with one LED mode-plugin as specified in the sketch. The template mechanism filters out any other plugins unrelated to LED modes. `LEDModeFactory`s thereby handle both static and dynamic LED modes.
Class `LEDModeManager` provides access to the LED mode factories and LED modes in general. It exports methods to query the number of LED modes and to activate a LED mode by its mode-ID. Most of this is only available to `LEDControl` that represents the actual user interface.
When a dynamic LED mode is activated, a dedicated `LEDModeFactory` generates an instance of the dynamic LED mode class in the
LED mode buffer. This buffer is shared by all dynamic LED modes. Its size has been determined at compile time by examining all exported dynamic LED mode types and determining the maximum necessary amount of RAM to store any of those.
All LED mode handling related data structures are generated at compile time, based on
the list of plugins that are passed to `KALEIDOSCOPE_INIT_PLUGINS(...)`. This function macro invokes a new function macro `_INIT_LED_MODE_MANAGER` from `LEDModeManager.h` that handles the LED mode related stuff.

Recently a proposed change to the firmware required a change to one of
the event handlers'/hooks' signatures.
Up to now, we only supported a single overload/implementation of a
event handler of a specific type. This means that changing handler signatures
was only possible by adding a handler method with a similar name and
a different signature like
EventHandlerResult
onKeyswitchEvent(Key &mappedKey, byte row, byte col, uint8_t keyState);
and
EventHandlerResult
onKeyswitchEvent2(Key &mappedKey, KeyAddr key_addr, uint8_t keyState);
As this was regarded as unacceptable confusion of the users of our
programming interface, this commit introduces some changes to the
event handler management.
Important changes:
* handlers can now be overloaded,
* handler signatures can be versioned,
* individual versions can be declared as deprecated,
* we now abort the compile if a handler reimplementation with a bad signature
is found,
* or if two or more handlers with correct signatures are detected that
are furtheron considered as ambiguous.
Impact on resources:
The proposed changes only affect the way things are handled at compile time.
No changes in terms of PROGMEM or RAM are to be expected.

This commit silences a warning due to an undefined variable.
A first attemt to locally supress the warning using compiler pragmas was
unsuccessfull due to a compiler bug in all gcc versions. This bug
in all gcc versions below 6.1 makes local diagnostics suppression useless.
As future versions of Arduino will ship with later versions of gcc
from a certain point on, the supplied warning suppression macros will become useful
to avoid the necessity to set global compiler flags like -Wno... and to
enable more precise warning suppression.
The new header file comes with an example that explains how to use
the suppression mechanism.

In general, we want method names to be verbs, because they convey actions. The

Furthermore, `Layer.next()` and `Layer.previous()` were even more confusing,
because one could easily think they implied moving to the selected layers, while
in practice, they just activated them.

In the original `KeyboardioFirmware`, this was used to store the default keymap
index in EEPROM. When we removed the EEPROM storage, it was meant to be used by
sketches to set a default layer (the minimum layer one can switch to), which was

and it wasn't used anyway.
For these reasons, it is now deprecated, and will eventually be removed.

Lots of things were already under the `kaleidoscope` namespace, but were in the
"wrong" directory. This big patchset moves everything under `kaleidoscope/`, and
namespaces `Layers_`. There are a few un-namespaced things, but because their
use is so widespread, and they're used so commonly, we don't want to namespace
those (like `handleKeyswitchEvent`), at least not yet.
As a minor side-effect, this moves a few global statics that were once in
`Layers.cpp` into the `Layer_` class itself, for clarity and encapsulation.
Non-namespaced headers that were used outside of Kaleidoscope itself will still
work, but will emit a compile-time warning.

With this redesign, we introduce a new way to create plugins, which is easier to
extend with new hook points, provides a better interface, uses less memory, less
program space, and is a tiny bit faster too.
It all begins with `kaleidoscope::Plugin` being the base class, which provides
the hook methods plugins can implement. Plugins should be declared with
`KALEIDOSCOPE_INIT_PLUGINS` instead of `Kaleidoscope.use()`. Behind this macro
is a bit of magic (see the in-code documentation) that allows us to unroll the
hook method calls, avoid vtables, and so on. It creates an override for
`kaleidoscope::Hooks::*` methods, each of which will call the respective methods
of each initialized plugin.
With the new API come new names: all of the methods plugins can implement
received new, more descriptive names that all follow a similar pattern.
The old (dubbed V1) API still remains in place, although deprecated. One can
turn it off by setting the `KALEIDOSCOPE_ENABLE_V1_PLUGIN_API` define to zero,
while compiling the firmware.
This work is based on #276, written by @noseglasses. @obra and @algernon did
some cleaning up and applied a little naming treatment.
