Usecase:
1. Install Fitbit app
2. Pair and connect with RD1
3. Start streaming
4. Pair and connect Fitbit watch

Failure:
No Stable Avctp connection with Fitbit Watch after pairing

Rootcause:
If there will be no listening acceptor
then some Remotes unable to connect AVRC
connection upon remote restart.

Fix:
Open acceptor channel for RC on cleanup
as if there will be no listening acceptor
then some Remotes unable to connect AVRC

Steps:
1. Pair and connect with HID mouse.
2. Once the settings UI shows paired and connected
3. Try to unpair the device, but UI still shows connected.

Failure: Unable to unpair HID mouse due to LMP
response timeout occurred for  remote version and remote
feature request.

Root Cause: Remote version, Remote features, Authentication
requested commands go simultaneously to the remote device
which can't handle the multiple commands at a time.

Fix: Serialize the Remote version, Remote features, Authentication
requested commands.

Test: Tested manually with apple magic mouse.

If OTA A2DP codec configuration is accepted from the remote
device, then don't trigger codec reconfiguration.

Bug: 74521894
Test: Manual: accept connection and codec config from A2DP Sink
Change-Id: Ic2f6ff08d130adf85cad68a54ab9fbc0a711534c

Use the existing mechanism for selecting the A2DP Source codec to
select the A2DP Sink codec when the local device is A2DP Sink.

* Added new method BtaAvCo::SelectSinkCodec() similar to
  SelectSourceCodec() and use the new method to select the actual
  codec based on the AVDTP Codec capability discovery.
* Renamed method BtaAvCo::UpdateSelectableCodec() to
  UpdateSelectableSourceCodec() and added similar
  UpdateSelectableSinkCodec()
* Renamed method BtaAvCo::AttemptCodecSelection() to
  AttemptSourceCodecSelection() and added similar
  AttemptSinkCodecSelection
* Renamed AudioSinkHasContentProtection() to AudioSepHasContentProtection()
  because it can be used for either A2DP Source or Sink
* Removed method BtaAvCo::FindPeerSourceSepForCurrentCodec() because it
  is not needed anymore.
* Added new method A2dpCodecs::findSinkCodecConfig() similar to
  findSourceCodecConfig()
* Added new function A2DP_SinkCodecIndex() similar to
  A2DP_SourceCodecIndex()
* Added new method A2dpCodecs::setSinkCodecConfig()
* Reorganize the SBC and AAC Source/Sink codec config classes:
  - Virtual method A2dpCodecConfig::setCodecConfig() is now implemented
    for Sink codecs as well: SBC Sink, AAC Sink
  - Renamed A2dpCodecConfigSbc to A2dpCodecConfigSbcSource
  - Renamed A2dpCodecConfigAac to A2dpCodecConfigAacSource
  - Added base class A2dpCodecConfigSbcBase. That class implements
    method setCodecConfig() for both A2dpCodecConfigSbcSource and
    A2dpCodecConfigSbcSink
  - Added base class A2dpCodecConfigAacBase. That class implements
    method setCodecConfig() for both A2dpCodecConfigAacSource and
    A2dpCodecConfigAacSink
  - Updated the A2dpCodecConfigAacBase::setCodecConfig() so it computes
    correctly the AAC Variable Bit Rate Support flag in the result codec
    config: The Variable Bit Rate Support is disabled if either side
    disables it.
* Removed A2DP_BuildSrc2SinkConfig() because it is not needed anymore.
  The correspinding A2DP_BuildSrc2SinkConfigSbc() and
  A2DP_BuildSrc2SinkConfigAac() are removed as well.
* Renamed a2dp_sbc_caps inside a2dp_sbc.cc to a2dp_sbc_source_caps
* Renamed a2dp_aac_caps inside a2dp_aac.cc to a2dp_aac_source_caps
* Added corresponding unit tests

Usecase:
1) Connect to HOGP device. (Because of some condition encryption fails with Connection
   Timeout, remote device turned off when connection was initiated)
2) Try to connect again to HoGP device

Expected Result:
Connection should be successful

Observed Result:
UI stuck in connecting state and connection never succeeds.

Root cause:
When encryption fails in previous iteration, encryption happens before HoGP Server starts
security procedure, leading to Encryption Complete event being received with wrong status.

Fix:
Update the status to success when sending encryption complete event if link is already
encrypted

Test: Issue is not seen after above steps

According to logs some devices are stuck when in BLE_CONN_CANCEL state.
That is they sent "LE Create Connection Cancel" request, and are
awaiting "LE Connection Complete" event with invalid handle forever.
But they wait and wait, and the event never arrive. That's because
"LE Create Connection Cancel" was sent, when connection attempt is not
pending. In such case, we should act upon command complete status, and
decide to leave BLE_CONN_CANCEL state.

To properly fix this issue, one would have to implement a proper queue
for managing LE connection attempt state, preferably for scratch. This
fix just give option of graceful recovery.

If the A2DP codec is changed for the active device, then
the current session is restarted by calling End/Start Session.

Also:
 * Updated btav_a2dp_codec_config_t string representation to
   include the codec priority.
 * Fixed A2dpCodecConfig::setCodecPriority() and setDefaultCodecPriority()
   so the codec priority for the current codec_config_ is updated.
 * Fixed A2dpCodecs::setCodecUserConfig() so the restart_input flag
   is set as appropriate.
 * Use btav_a2dp_codec_config_t::ToString() as appropritate to print
   the codec config instead of explicitly printing each field.

Start/End session is called when setting/changing the Active (remote)
device.

Also:
 * For A2DP Source, btif_a2dp_source_setup_codec() is called only for
   Start session. All other calls to btif_a2dp_source_setup_codec are
   removed.
 * Updated the btif_a2dp_source_setup_codec() implementation to
   call btif_a2dp_source_audio_tx_flush_req() and flush the incoming audio
   data. This removes 2 seconds hold-up delay when switching the active
   device and streaming audio.
