Removed A2DP_GetTrackBitsPerSample() API because it is not needed
The A2DP_GetTrackBitsPerSample() API was replaced in the past
by A2dpCodecConfig::getAudioBitsPerSample() .
* Removed A2DP_GetTrackBitsPerSample() and related codec-specific APIs:
- A2DP_GetTrackBitsPerSampleSbc
- A2DP_GetTrackBitsPerSampleAac
- A2DP_GetTrackBitsPerSampleAptx
- A2DP_GetTrackBitsPerSampleAptxHd
- A2DP_GetTrackBitsPerSampleLdac
NOTE: The removed A2DP_GetTrackBitsPerSampleLdac implementation
had a bug: a2dp_ldac_caps.bits_per_sample -> ldac_cie.bits_per_sample
This bug itself was uncovered when switching to clang-3960126
- A2DP_VendorGetTrackBitsPerSample()
* Replaced few leftover usages of A2DP_GetTrackBitsPerSample()
A2dpCodecConfig::getAudioBitsPerSample()
* Updated the unit tests
Test: Code compilation, unit tests, A2DP streaming

Add A2DP codec-specific information to dumpsys output
Now we print the following information:
* Current codec name
* Info for each supported codec:
- Priority
- Encoder interval (ms)
- Codec Config: Sampling rate, Bits per sample, Channel mode (MONO/STEREO)
- Selectable codec configuration
- Codec's local capability
- Packet counts (expected/dropped)
- PCM read counts (expected/actual)
- PCM read bytes (expected/actual)
* LDAC codec-specific info:
- LDAC quality mode: HIGH/MID/LOW/ABR
- LDAC saved transmit queue length [used in ABR mode]

Add a mechanism to configure the default A2DP codec priorities
Previously, the relative codec priorities were hard-codec internally.
The new mechanism uses the following configurable resources in
packages/apps/Bluetooth/res/values/config.xml to re-assign the
default codec priorities per device, or to explicitly disable a codec.
- a2dp_source_codec_priority_sbc
- a2dp_source_codec_priority_aac
- a2dp_source_codec_priority_aptx
- a2dp_source_codec_priority_aptx_hd
- a2dp_source_codec_priority_ldac
Those values are assigned on startup.
Also, they can be changed per device by using an overlay:
device/<VENDOR>/<DEVICE>/overlay/packages/apps/Bluetooth/res/values/config.xml

Update the A2DP Codec Config API
Previously, the JNI upcall would contain only the current codec config.
In the new API, the upcall contains:
1. The current codec config
2. The list of codecs containing the local codecs capabilities
3. The list of codecs containing the selectable codecs capabilities.
This list is the intersection of the local codecs capabilities
and the capabilities of the paired device.
Also, updated the codec backend to accomodate the above changes:
* Update all selectable codecs inside bta_av_co_audio_set_codec()
* Changed getCodecConfigAndCapabilities() to return current codec
config, local codecs capabilities, and selectable codecs capabilities.
* Updated each codec to compute and store a copy of the selectable
capabilities, and the local capabilities.
* Updated tA2DP_SBC_CIE to include new field bits_per_sample
(for consistency with the rest of the codecs).
* Replaced usage of codec_priority of 0 with BTAV_A2DP_CODEC_PRIORITY_DEFAULT
* If there is user codec (re)config call, we always send an upcall
to inform the Java layer about the most recent codec info.
Thus, the caller would always know whether the request succeeded or failed.

Removed the feeding_init call from tA2DP_ENCODER_INTERFACE
The feeding_init call is not used anymore - it has been superseded
by the newer A2dpCodecs.setCodecAudioConfig() mechanism.
Also, moved aptx_init_framing_params() and aptx_hd_init_framing_params()
calls to the corresponding encoder_update functions.

Renamed the aptX and aptX-HD shared libraries
* The names of the expected aptX and aptX-HD shared libraries are
updated to reflect better their purpose:
- aptX: libaptX.so -> libaptX_encoder.so
- aptX-HD: libaptXHD.so -> libaptXHD_encoder.so
Also:
* Add a missing upcall with the codec info the first time the codec
is selected internally
* Minor cleanup

Integration of the LDAC codec for A2DP source
The codec can be used if the encoding shared library is installed

to 6 to accomodate Sink devices that support more than 3 codecs.
