noseglasses	8130dfdf1d	Major redesign of the plugin and hooking interface 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.

Major redesign of the plugin and hooking interface

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.
