Using call by reference in FocusSerial::send(...) and
FocusSerial::sendRaw(...) causes linker errors due to
undefined symbols if constexpr constants are passed to the
methods.
This is because if a constexpr value is bound to a reference
this is the same as taking the address of the value. Thus,
the compiler has to generate an instance. Some constants
like e.g. FocusSerial::NEWLINE do not come with an
instance.
This seems not to cause problems with avr-gcc up to now
but generates linker errors during virtual compiles with later gcc
versions (e.g. gcc 8.3.0).
This change does not incur any additional overhead as
all version of FocusSerial's send methods are already inlined,
and the templated versions root to the non-template versions of the send
methods that only accept call-by-value anyway.

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.

We have a few AVR-specific things which do not have a guard yet, and cause
issues on other architectures. This adds those missing guards to the following
places:
- The `kaleidoscope::Hardware` base class, which is deprecated, but still
exists. As such, it needs to be restricted to AVR devices only (since that's all
it supported, non-AVR devices should use the new APIs).
- `device/keyboardio/twi` are only used by the Imago at the moment, and is
AVR-specific, so guard that too.
- Removed an unneeded include from `driver::bootloader::None`, because it
doesn't need `<avr/wdt.h>`.

Having to recompile and re-flash firmware to set the idle timeout of the plugin
isn't a fun or desired experience. It's fine when one already figured out the
timeout they want, and have no desire to change it. For everyone else, being
able to configure it at run-time via Focus, and have it persist to EEPROM is a
much nicer experience.
This change adds an alternative version of the plugin, `PersistentIdleLEDs`, a
subclass of the original one. This one provides the focus command and
persistence. It's a child class, because that results in a smaller footprint
than a separate plugin that calls the `IdleLEDs` object.

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`

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

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.

- The direct dependence on KeyboardioHID is removed by only flushing one event
from the queue per cycle.
- The array of Qukey objects is now stored in PROGMEM instead of SRAM, and is
configured via an array reference template function in order to automatically
ensure the count will be correct.
- There is a new algorithm for determining which state a qukey will collapse
into in the case of rollover from qukey to another key, which should reduce
the rate of errors for "sloppy" typists.
- A Qukey with a primary key value that is a modifier (including layer shift
keys) is treated like a SpaceCadet key, with different semantics. The
alternate (non-modifier) key value is only used if the SpaceCadet key is
pressed and released on its own, without rolling over to any other key.
- The code is generally simpler and easier to understand, with better inline
comments explaining how it all works.

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.

A traits class that is used to check if a class implements a
method with a given signature was already used by
the eventhandler signature check. It has now been moved to
its own traits header (macro name is DEFINE_HAS_METHOD_TRAITS).
