* Add `bt` behavior that can be used to perform certain actions,
such as next/prev identity, reset identity, etc.
NOTE: Multiple identities is only supported for non-split shields,
due to missing Zephyr identity functionality for dual
central/peripheral devices.
* Proper bond reset tied to action, that honors peripheral bonds,
so folks can reset and pair to other hosts, without breaking
bonds between splt halves.
* Especially for splits, we need the ability to
unpair all paired devices as sledgehammer
if we need to "reset things", and doing so via
keymaps isn't suitable.
* Allows shields to define a collection of key
positions that if all held 2 seconds after
startup, will unpair all existing pairs for the
device.
* Service for split peripheral to report
position state to split central.
* Updated advertising info.
* Behavior for split BT until we have a proper
event system.
* Add initial event manager implementation,
roughly mimicking Nordic's API.
* Add `position_state_changed` and
`keycode_state_changed` events.
* Hook up HID and keymap to new events
instead of using behaviour global event
crazy.
* Refactor Kyria into separate left/right "revisions"
of the Kyria shield, and include central
kyria.dtsi file with common definition.
* Fixes for keymaps to work fully with matrix
transforms that override effective rows/columns.
* Add ability for matrix transform to do row/col
offsets, which is needed for split keyboards.
* Basic Clueboard Californai Macropad shield definition.
* New "direct" KSCAN driver that supports non-matrix direct
wiring for switches, needed for macropad that doesn't have
a matrix at all.
* Some renames for existing KSCAN GPIO driver to make the implied
"matrix" part explicit.
* Use extra comptible = "zmk,behavior-global" to add
behaviors to global bindings for event notification.
* Implement mod-tap, as a keymap binding and global one
to skip tap if other keycode pressed while held.
* Allows "gaps" for keyboards like Kyra.
* Allows keyboards with matrixes that don't map the logical key
locations to have normal looking keymaps when defined.
