Rename struct rtp_payload to rtp_sbc_payload as it is specific for SBC
codec. Add proper checks for endianity in rtp.h header and use uint8_t type
where appropriated. And because rtp_sbc_payload structure is not parsed by
decoder there is no support for fragmented SBC frames. Add warning for it.

Some A2DP codecs (e.g. SBC or aptX-HD) use RTP packets. For sources use
timestamps from RTP packets to calculate read index and therefore remote
timestamp for synchronization.

Each codec has different compression ratio and own method how to calculate
buffer size of encoded or decoded samples. So change A2DP codec API to
provide this information for module-bluez5-device module and fix
a2dp_prepare_encoder_buffer() and a2dp_prepare_decoder_buffer() functions.
API function
This patch provides support for FastStream codec in bluetooth A2DP profile.
FastStream codec is bi-directional, which means that support both music
playback and microphone voice at the same time.
FastStream codec is just SBC codec with fixed parameters. For playback are
used following parameters:
This patch provides support for aptX and aptX HD codecs in bluetooth A2DP
profile. It uses open source LGPLv2.1+ licensed libopenaptx library which
can be found at https://github.com/pali/libopenaptx.
aptX for s24 stereo samples provides fixed 6:1 compression ratio and
bitrate 352.8 kbit/s, aptX H
Changes in v10:
* SBC: Mark const table with "const"
* SBC: Fix choosing frequency
* SBC: Fix checking for channel mode capability
* SBC: Fix usage of RTP structures
* aptX-HD: Fix calculation of buffer size
* aptX-HD: Wrap data to RTP packets
* Fix choosing initial profile, use directly bluetooth
Bluez and remote device decide which A2DP codec would use. Use this
selected A2DP codec as initial profile in pulseaudio.
In most cases it is either last used codec or codec with higher priority by
defined by remote device.
To detect which A2DP profile was activated by bluez, look at bluez
transp
In next patches, codec name is appended end the end of a2dp profile names.

Specify configuration for Low, Middle, High and Ultra High Quality of SBC
codec. SBC codec in Ultra High Quality has higher quality than aptX.
Automatic Quality mode matches configuration of SBC codec which was used
before this change. Which means that it accept configuration between Low

Previously module-bluetooth-policy was switching from A2DP to HSP profile
when VOIP application started recording of source. Now it switch to profile
with the highest priority which has both sink and source. In most cases it
is HSP profile, but it can be also bi-directional A2DP profile (e.g.
FastS
Some A2DP codecs (like FastStream or aptX Low Latency) are bi-directional
and can be used for both music playback and audio call. This patch
implements usage of backchannel if A2DP codec provided by pulseaudio API
supports it.
A2DP codec switching needs new version of bluez as older version does n
