* Move to local/stack allocated event API that doesn't require
dynamic allocation/freeing.
* Disable heap, we no longer use alloc/free unless using LVGL.
* Tons of refactors all over to account for the new event approach.
Note there was one place where a non-strict prototype was actually being used
with an argument, in `zmk_hog_init`. In this case, the actual argument type was
added instead.
* USB boot protocol support
* Use a single definition of a boot report, used for regular reports in
non-6KRO, and for rollover in all branches.
* Handle gaps in the zmk report when producing a boot report in HKRO mode. For
.example, if it was 8KRO, it would be possible to have the state 0 0 0 0 0 0 0
17 (by pressing 8 keys, and letting go of the first 7). Copying the first 6
bytes would not show up the single pressed key.
* Disable usb status change and callback on SOF events:
SOF events were introduced by the boot protocol changes, and required internally
by Zephyr's idle support, but are unused within ZMK itself. Ignore them in the
usb status callback.

All credit for this one goes to @xudongzheng (thanks for helping debug
this!). Should fix the issue where keyboards go unresponsive after their
host machine wakes from sleep due to the USB driver entering an error
state. I was able to both reliably reproduce the issue before the patch
goes in and confirmed it no longer occurs post patch.
The `USB_DC_RESUME` state indicates the host event has resumed the connection.
Adding it to the list of valid connection states to prevent the error
when waking from sleep.

* Make it easier to use *just* event payloads by defining the data,
and then having event manager macros generate "wrapper structs"
* Improve is_*/cast_* APIs to hide details of full event struct.
* Create `zmk_event_t` typedef to pass to event handlers.
* Bring event names inline w/ consistent `zmk_` prefix.
Aligns *.h and *.c to underscore naming convention.
These were kept (with warnings) for backwards compatibility with external boards/shields:
- kscan-mock.h
- matrix-transform.h
They should be removed in the future.
PR: #523
Added some utility functions and an event for tracking the state of the
USB connection.
Updated endpoints.c to select a single endpoint to send HID reports to
based on the status of the USB and BLE connections. Partially fixes#206.
Future commits will add a user setting to control which endpoint is used if
both USB and BLE are ready.
