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
Bug: 37752547

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]
* SBC codec-specific info:
- Frames counts (expected/dropped)
Sample of the new format is below:

Reduced the log verbosity level for aptX/aptX-HD data packets
Also, fixed a typo in a log message.

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The feeding_init call is not used anymore - it has been superseded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

Each of the codecs can be used if the corresponding encoding
shared library is installed on the device:

- aptX-HD: libaptXHD.so
