Setting AFB_BINDING_VERSION is cmake makes merges
easier between branches, since it is always defined
once at a single place instead that in each file
that need it.
Also removed the "INSTALL" section with LIBRARY_DESTINATION
since it is now treated in app-templates.

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.

To avoid the GPL licensed code in rtl_fm.c making all of the binding
GPL, rework things to wrap it with a simple standalone helper
executable that is driven via stdin/stdout. While this could
potentially be done by running the original unmodified rtl_fm utility
itself, it would be impossible to implement scanning with that
approach without some compromising of playback latency and quality.
The current helper implementation is simple enough that replacing it
with an alternate one should be relatively straightforward if that is
desired.

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.
