We want to allow plugins to change how keys are looked up - or where they are
looked up from -, and for this, the way we do that final lookup from `keymaps`
or elsewhere, must be overrideable.
We do this by having a `getKey` function pointer in the `Layer_` class, which
defaults to `getKeyFromPROGMEM`. Any plugin, or sketch, can change where
`getKey` points to, and thereby change the way keys are looked up.

If we want to allow plugins to implement EEPROM storage, it is best if we don't
do anything with EEPROM in the core firmware. As such, remove the
`Layer.defaultLayer` call from `Kaleidoscope.setup`.
With that gone, the `keymap_count` argument is obsolete, so drop it from
`Kaleidoscope.setup()` - but we keep an temporary `setup()` with the old arity,
so that plugins can be updated at a slower pace.

The `USE_PLUGINS()` macro is a clever hack, to make it seem like
`Kaleidoscope.use()` is type-safe. It pushes its arguments into an appropriately
typed array, so anything that does not fit the criteria, will trigger a compiler
error.
It then never uses the array, and passes the plugins over to
`Kaleidoscope.use`, adding the trailing `NULL`, making it even easier to
use.
Since the array this macro creates is never used, the compiler will
optimize it out fully. As such, by using this macro, we incur neither
any size penalties, nor any run-time penalties. Everything happens at
compile-time.
Fixes#100.

To make things easier, just include the main header. It includes
everything else we need, and this way we do not need to cherry pick, nor
care if any of the other headers move, disappear, etc.

Having the hooks, and the hook methods in the Kaleidoscope object means
we don't have to litter the definitions of the arrays around, and that
the hooks are more tied to the object. We pollute the global namespace
less, and having them in the object means that the hook helper functions
will not be optimized out if not used within the Kaleidoscope repo.
All in all, this saves us about 56 bytes of code, allows us to remove
some hacks, and pulls things that are closely knit, closer together.
While there, also changed the name of the `custom_handler_t` and
`custom_loop_t` types to `eventHandlerHook` and `loopHook` (both under
the `Kaleidoscope_` class), to better reflect what they are for.

The plugin.h header only defined the KaleidoscopePlugin class, and while
there was a reason it was separate from Kaleidoscope.h, that reason is
long gone. Merge it there, and remove any reference to plugin.h, as it
is not needed anymore.

Since we pre-fill the cached `keyMap` with the value of `DefaultLayer`, there is
no need to check that layer again, looking for a non-transparent key. Whatever
is there, will be used anyway.
This way we save a cycle for keys that are transparent everywhere but the
default layer.

We fill the cached `keyMap` with the value of `DefaultLayer`, so if that is the
only layer active, then we can bail out early.

Instead of going through all the active layers each time we are looking for a
key, whenever we switch layers, compute the effective keymap, and store the
indexes. This makes the lookup a considerably faster operation, and lookups
happen far more often than layer switching.
This comes at a cost of ROWS*COLS amount of memory, and a bit of code, but on
the flip side, the lookup operation is now O(1), which is a very nice property
to have, if you want responsiveness. Changing layers is marginally slower,
however, but even with 32 active layers, doing the computation once, instead of
potentially many dozens of time, is still worth it.
We could further reduce the memory requirements if we stored more columns per
byte, but that's for a future optimization.

The build-all command needs a clean(-ish) slate, and must re-set the build-dir,
otherwise a successful build of a previous plugin will remove it. As a
workaround, re-launch the builder in this case.

Instead of always iterating through all layers, which slows us down
considerably, keep track of the highest active one, and start from there.
This has a VERY noticeable impact on the speed at which we finish a scan cycle.

Momentary layer switchers were broken, because they had the flags/keyCode parts
swapped. Apparently, I missed these when swapping the rest.

The function is broken, and does not belong here in the first place. It was a
remnant of how Akela was set up, but makes no sense in general.

It had the COLS & ROWS defines, which are hardware-specific, and were moved to
the hardware lib.
Signed-off-by: Gergely Nagy <algernon@madhouse-project.org>
Moved all of the hardware-specific code to a separate library. As such, use the
special `KEYBOARDIO_HARDWARE_H` define to include the appropriate header, as set
by the board's `boards.txt`.
