Repurpose repository into a spiritual successor of the previous
binding. The backend code is retained behind a new gRPC API
defined in protos/radio.proto. The simpler synchronous gRPC API
had been used for expediency, this may warrant revisiting to
rework into an async or callback API based server instead. As
well, authentication has been left until some consensus on an
approach can be worked out.

The lazy startup of the separate helper program for the RTL-SDR
backend on playback start was incorrect with respect to the expected
behavior the frequency setting verbs. This was not visible during
usage by the radio application, but was triggering failures in
several tests in the pyagl binding wrapper test suite. To facilitate
starting the helper during backend initialization, the probing part
of the backend "init" has been split into a separate "probe" function,
and all backends have been updated to reflect this change. Logic has
been added to enforce that "init" is only called after "probe" has
succeeded for a backend, and a comment has been added to radio_impl.h
to document this intended behavior.

The frequency verb was not checking if a frequency corresponds to the
frequency band step the binding provides to users, add logic to do so
and return an error if the frequency is invalid. While this is a
change in behavior, it is believe it should not impact users, as the
binding is intended to reflect user facing radio application usage.
Additional tweaks:
- fix error invalid frequency error message in reply JSON.
- add the same band limit checks to the null implementation's
frequency setting function that the other implementations do.
- fix a couple of issues in README.md; the "rds" verb was missing,
and the value key name for the "frequency" event was incorrect.

Changes:
- Add null radio implementation that acts as the fallthrough default
when the hardware implementations are not detected.
- Tweaked the probing in the tef665x implementation to not return an
error if the I2C node is not even present. This cleans up the logs
on start up on most platforms. These changes include some minor
whitespace consistency clean ups.
- Added the run-by-default widget permission now that the binding
should always work. This will ease testing, and potentially decrease
app start up time.

This is a NXP tuner AM/FM/RDS. The chip has analogue and digital sound
output and input. Chip is controlled through i2c.
I had to add a sound cart to the kernel to be able to capture the i2s
data from the chip.
Some of the verbs still to be implemented. I test it on a costum board
with imx6solo.

Fixes:
- Track playing state in binding code to properly ignore signal-composer
events when not playing.
- Add changing of pipeline state in response to the GstBus
GST_MESSAGE_REQUEST_STATE message to the KF code, this is required to
have the second request to switch back to PLAYING state be sent, and
hence properly keeping track of corked state. Also added required
gstreamer main loop so GstBus actually works.
- The alsasrc used in the KF code's gstreamer pipeline seems to not
handle the switch to READY state on pause (currently required to
trigger Wireplumber policy) as expected; it seems to keep feeding the
pipeline, causing long stalls on restart. For now, taking the stream
fully down to NULL state seems to work around this issue.

Add initial basic support for next/previous events from signal composer,
mapping them to seek forward/back. More work will be required to handle
the issues around both mediaplayer and radio both being running and
differentiating which should handle the events.
Additionally, complete transition to binding version 3 to clean things
up.

Rework things so that the 4A audio role is only opened while playing,
and closed when stopped. Further work will need to be done to handle
the possibility of the output device changing on subsequent opens,
both the RTL SDR and Kingfisher case have complications around doing
so:
- The RTL SDR helper application needs to be enhanced to add an
output setting command. Killing it and starting it again would
also work, but likely will add noticeable UI latency.
- On the Kingfisher, the binding currently has no control over the
output used for the loopback, as it is being set up down in the
soft-mixer based on HAL values.

Changed the api call for getting an audio role.
Mapped the stop/start operations to mute/unmute
actions on role verb.
No longer uses a gstreamer pipeline for the sound
output, since it is 4a-softmixer that performs
the read/write loop instead.

When building for 4A, switch to new gstreamer-based ALSA output for
the RTL-SDR backend, and the Kingfisher backend now uses a gstreamer
pipeline for its loopback to either an ALSA or Pulse sink depending
on 4A or not. Using gstreamer instead of direct ALSA output has the
benefit of transparently handling resampling to the M3ULCB hardware's
required 48 KHz sample rate for the RTL-SDR backend.

Make Kingfisher support unconditional to move all platform
detection to run-time. This fixes the issue of violating the
application build workflow with the SDK. Additionally, the
Kingfisher detection has been improved with an added check
for the Si4689 device-tree node to differentiate from a
regular M3ULCB, and the Kingfisher output has been fixed for
recent BSP changes.

Add conditionally compilable support for the Si4689 radio on the
M3ULCB Kingfisher infotainment board. The codebase has been
refactored to allow multiple radio implementations, and when
Kingfisher support is enabled, the binding will first look for a
USB RTL-SDR adapter, then fallback to the Kingfisher Si4689 if
one is not found. This allows easily switching to a RTL-SDR
adapter if this initial Kingfisher support encounters issues.
The back end implementation relies on a patched version of the
"si_ctl" utility from Cogent Embedded's Kingfisher BSP changes.
The modifications to it add FM band plan selection and scanning
threshold tweaking for poor radio environments. Audio output is
achieved by looping the radio's PulseAudio source to the
appropriate sink depending on 4A or non-4A operation. For 4A
compatibility, the PulseAudio source is created if it does not
exist, which currently is the case due to PulseAudio's udev
module being disabled when 4A is enabled.
Additionally, the FM band plan for Japan has been corrected to go
to 95 MHz, and a README.md file has been added documenting the
optional configuration that can be done via /etc/xdg/AGL.conf for
band plan selection and scanning sensitivity.

Recent testing found that the verbs no longer work now with the
AFB_SESSION_CHECK flag set on them and the binding split out to be
standalone from the app. Since the radio does not really need the
concept of a session, switch to AFB_SESSION_NONE to get things
working, rather than add the extra infrastructure to enable session
support.
