* Add bindings to allow creating multiple physical layouts that specify
their key's physical attributes, and the matching matrix transform
and dependant kscan to use.
* Synthesize a basic physical layout if none specified, for backwards
compatibility.
* Update matrix transform API to explicitly pass in the selected transform
to the API instead of using a fixed chosen transform.
* Move kscan subscription and handling into the physical layout code, so
that selecting a different physical layout at runtime can also use the
correct kscan instance.
* Add `physical_layouts.dtsi` file to include so you can use the
pre-configured `&key_physical_attrs` for adding you layout keys.
* Add a new feature for tracking a given behavior by a new concept
of a "behavior local ID" which is a stable 16-bit identifier for
a given behavior, that is resilient to new behaviors being added
and requires no additional work on the part of the behavior
authors.
* Add implementations for either settings lookup table, or CRC16
hashing of behavior device names for generating behavior local
IDs.
* Instead of gpio key behavior trigger, add new kscan driver that
decorates/wraps a given kscan driver and will invoke basic system
behavior assigned to a given row + column, without the need for keymap
mapping in the matrix transform, bypassing keymaps entirely.
* Better naming for gpio-key behavior triggers.
* Tweaks to scanned behavior trigger to avoid bad semaphore use,
and reduce chance of issues with slowly scanned matrixes.
* Various code cleanups of style issues.
Initial work on a soft on/off support for ZMK. Triggering soft off
puts the device into deep sleep with only a specific GPIO pin
configured to wake the device, avoiding waking from other key
presses in the matrix like the normal deep sleep.

Added a zmk_settings_erase() function to clear all saved settings. This
does not go through Zephyr's settings subsystem, but instead directly
clears the data from the setting storage backend, so a reboot is needed
for it to take effect.
* Add a new Kconfig symbol to enable the low priority queue, and make
the two features that depend on it `select` the symbol to turn it on.
This helps ensure no wasted RAM/ROM on devices that don't need it.
* Shift to using an extra Zephyr module to do keymap location
work after all board roots are resolved. This avoids duplicate work
and allows us to load custom boards from Zephyr modules as well as
user config setups.
Added BEHAVIOR_DT_DEFINE() and BEHAVIOR_DT_INST_DEFINE(), which work
exactly like the DEVICE_*_DEFINE() macros, except they also register the
device as a behavior by adding a pointer to it to a memory section.
Added zmk_behavior_get_binding(), which works like device_get_binding()
except that it only searches the devices that have been registered as
behaviors. This ensures that behaviors cannot have name collisions with
other devices defined by the SoC, which will be important when we remove
the label property from behaviors so they are given their node names.
As an added benefit, this is faster since it searches a smaller list.
Some basic benchmark code I wrote indicates it takes 30-70% as long,
depending on where the behavior is in the list and whether the name
string is an exact pointer match.
From now on, behaviors should use BEHAVIOR_*_DEFINe() instead of
DEVICE_*_DEFINE(), and any code that looks up a behavior by name should
use zmk_behavior_get_binding() instead of device_get_binding().
* Add HID report/descriptor for a new report with mouse buttons,
and x/y/wheel deltas.
* New mouse key press behavior for press/release of mouse keys.
* Add constants for HID main item values (e.g. data/array/absolute)
* Define and use constants for our HID report IDs.
* Add two new compatibles for macros that
take one or two parameters when bound in
a keymap.
* Use `¯o_param_1to1`, `¯o_param_1to2`, `¯o_param_2to1`,
and `¯o_param_2to2` control entries in the bindings for the macro
to have the next binding entry have it's values substituted.

* Add new sensor behaviors that either take full bindings
add definition, or accept parameters when bound in the
keymap.
* Remove existing hard-coded key press sensor behavior
and instead leverage new generic sensor behaviors to
achieve the same functionality.

* Move to ZephyrBuildConfig package based on Zephyr best practices.
* Support multiple shields properly, e.g. -DSHIELD="foo bar", which
allows using existing upstream shields like `ssd1306_128x64` along
with another ZMK shield.
* Properly *add* the "ZMK config" .conf file to the conf file list,
so that existing board .conf files in `app/boards/<board>.conf` are
properly honored still. Needed for overrides to usptream boards when
combined with a local `<shield>.conf` file.
* Add new API/status to track state of the
peripheral connection to the central.
* Add new peripheral status widget for displaying
the current status of the connection to
the central.
* Add strlcpy from public domain version.
* Leverage strlcpy to detect truncation of behavior dev strs, and log.
* Use `offsetof` for cleaner detection on peripheral side.
* GATT characteristic allowing passng data + behavior
label to invoke the behavior on the peripheral side.
* Behaviors have a locality setting to specify where they run.
* Build reset/power/RGB on peripheral.
This is a generalization of the existing concept of tri-layer support
that's already well known. Essentially, a conditional-layer
configuration activates a particular layer (the then-layer) when one or
more other layers (the if-layers) are activated.
This is commonly used on ortho keyboards to activate a third "adjust"
layer while the primary two layers ("lower" and "raise") are active.
