This commit adds a new template hook exploreSketch() that allows plugins to efficiently
obtain compile-time known information about the sketch.
The hook is called before setup and is passed a _Sketch
template parameter that wraps two more types Plugins and StaticKeymap, whose static constexpr methods can be used
to explore the registered plugins and the static keymap.

Hook methods can now be templated.
A template parameter type list, a list of template parameters and
a list of dummy template arguments have been added to the
macro arguments used in _FOR_EACH_EVENT_HANDLER.
Non-template hooks pass empty parenthesis for the three newly
introduced macro arguments.

We'd like to be able to run custom code whenever the led mode changes, reliably,
without having to resort to checking the mode every cycle. For this purpose, we
introduce the `onLEDModeChange()` handler plugins can hook into. It will be
called every time `LEDControl.set_mode()` is called, even if that just sets the
mode to the currently active one.

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.

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.

The intent is to make it easier for plugins to detect layer changes and schedule
work accordingly. There event receives no arguments, the current state can
always be queried with `Layer.getLayerState()`, and if a plugin requires the old
state too, they can track that on their own.

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.

After talking with Jesse, this changes the license to GPLv3 (only), where
appropriate, and adds copyright headers to all files that were missing them.

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.
