This was done to enable separate inclusion of the central runtime
class without having to include the central header
kaleidoscope/Kaleidoscope.h which used to pull in a lot of stuff that is
not required in many compilation units.
The new class `Runtime_` lives in namespace kaleidoscope its singleton
instance is `kaleidoscope::Runtime`. It is now only available internally
in library Kaleidoscope but not from the sketch.
The original class name `Kaleidoscope_` in global scope has been deprecated.
The original instance name `Kaleidoscope` in global scope has been
preserved to be used by end users in their sketches.

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.

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.

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.
