A2DP: Construct BtWorkerThread's message loop on designated thread
* Moves BtWorkerThread's message_loop_'s construction to the
Run() method run by the designated message_loop_thread_ so that
message_loop_'s construction and execution are on the same thread
* Makes BtWorkerThread::StartUp() blocking until message_loop_
starts running using std:condition_variable
* Modify BtWorkerThread::DoInThread() to return boolean
Detail:
Before this CL, BtWorkerThread.message_loop_ is created on Java main
thread and run on message_loop_thread_. During clean-up, A2DP shutdown
message_loop_thread_, rendering the posted_from field in current_pending_task_
invalid. However, although the runner thread is killed, the owner
thread, the Java main thread, is still active. Therefore, we we try to
PostTask() from Java main thread after message_loop_thread_ is killed,
we will try to access an invalid Location object. This results in a
SEGV_MAPPER SEGFAULT. Thus, the fix would be creating and running the
message loop on the same thread so that Java main thread won't have an
invalid message loop after the worker thread is killed.
This can be detected earlier through adding "-DDCHECK_ALWAYS_ON" in both
libchrome and libbluetooth and libchrome will validate the thread for
us.

Add a workaround for A2DP devices that request Role Change
Certain A2DP devices request Role Change after connection,
and typically the Phone grants it - as a result the Phone is the Slave.
However, with Multi-A2DP, follow-up A2DP connections require that the
Phone becomes the Master: within the existing stack we have function
bta_av_switch_if_needed() that checks whether the Phone needs to request
Role Change and become again the Master.
Some A2DP devices will refuse the Phone to become the Master again, and
this prevents/blocks the Phone from having multiple A2DP connections

Add support for Multi-A2DP state machines per device
* Reimplement most of the BTIF AV state machinery in C++
- Separate the BTIF AV Source from BTIF AV Sink state:
btif_av_source and btif_av_sink
- Remove the single btif_av_cb control block instance
- Add C++ based BtifStateMachine and remove the older C-based
btif_sm state machine
- Introduce C++ class BtifAvPeer to keep state per peer, and use
a single state machine instance per peer
- Update BTA_AvStart() and BTA_AvStop() to take tBTA_AV_HNDL handle
argument
- Register the BTA handles when enabling the Source/Sink service.
This needs to be done in advance during service startup, otherwise
a connection to a remote device will fail.
- Move local event_handler functions inside C++ ProcessEvent methods,
and pocess the BTIF, BTA AV and BTA AVRCP events per state machine
instance
- Cleanup callbacks and use do_in_jni_thread() to schedule the processing
- Add BTIF AV API that needs to be called by the AVRCP module for certain
AVRCP events: btif_av_avrcp_event_open(), btif_av_avrcp_event_close()
btif_av_avrcp_event_remote_play()
- Add a mechanism to set the active device
- Add BluetoothDevice argument to the codec-related internal Binder
APIs: getCodecStatus(), enableOptionalCodecs(),
disableOptionalCodecs(), setCodecConfigPreference()
- Rename btif_av_move_idle() to btif_av_acl_disconnected() and
refactor the processing to happen within each state machine on the
correct thread.
- Process cleanup_src and cleanup_sink on the JNI thread
- Add a mechanism to track the maximum number of connected devices.
- Add unit tests for the new BtifStateMachine class
* Redesign some of the AVDTP internals so it can handle multiple connected
devices
- Change some of the AVDTP struct entries to C++ classes.
This simplifies significantly the design fixes
- Reorganize the AvdtpScb entries: for each connection the
corresponding SEP entries are within the corresponding AvdtpCcb entry.
- Pass peer address as argument to the API functions inside bta_av_co.cc,
and update the peer address inside the corresponding peer entry in
bta_av_co.cc
- Add various log mesages
- Store precomputed BTA AV SCB index in the AvdtpCcb entry and use it as
appropriate.
- Fix the TCID computation and handling for the AvdtpAdaptationLayer
- Fix the computed value for AVDT_NUM_RT_TBL
- Remove video-related code inside AVDTP
- Refactor/cleanup hard-coded callbacks that depend on the BTA_AV_NUM_STRS
value.
- Update various #define values to support a larger number of connected
devices:
- Maximum number of streams:
BTA_AV_NUM_STRS: 2 -> 6
- BT_RC_NUM_APP: 1 -> 12 (AVRCP-related - 2 * MaxDevices)
- MAX_L2CAP_LINKS: 7 -> 13
- MAX_L2CAP_CHANNELS: 16 -> 32
- AVDT_NUM_LINKS: 2 -> 6
- AVDT_NUM_SEPS: (6 * AVDT_NUM_LINKS) -> 6
Now the value is used for the maximum number of SEPs per device
- AVDT_NUM_TC_TBL: 6 -> (AVDT_NUM_SEPS + AVDT_NUM_LINKS)
- AVCT_NUM_LINKS: 2 -> 6
- AVCT_NUM_CONN: 3 -> 14 (2 * MaxDevices + 2)
Also:
- Update the JNI codec-related calls to use const reference
instead of a pointer
- Update the implementation of bta_av_chk_2nd_start() so it is aligned
with bta_av_chk_start() and cleaned up both functions.
- Rename btif_dispatch_sm_event() to btif_av_dispatch_sm_event() and
btif_report_source_codec_state() to btif_av_report_source_codec_state()
for consistency with the rest of the BTIF AV API.
- Add new function btif_rc_is_connected_peer() and remove
btif_rc_get_connected_peer()
- Add new AVRCP header file btif/include/btif_rc.h
and move the AVRCP "extern" declarations from btif_av.cc there.
- Rename btif_av_execute_service() to btif_av_source_execute_service()
- Cleanup the btif_av.h API descriptions

Use weak pointer when refering to AdvertisingManager
In btif layer, we schedule tasks for execution on
AdvertisingManager on bta thread. Before the scheduling we check if
AdvertisingManager is initialized. We don't check if AdvertisingManager
is still valid, when the command execution is starting on the bta thread.
This is a race condition, that can cause crashes.
To fix that, always post task for execution using weak reference, rather
than raw pointer. Thanks to it, the MessageLoop will check if the
weak_ptr is valid before attempt to execute the task. The check happens
on the target thread, right before the execution, eliminating all
possible race conditions.

HFP: Use base::Bind instead of messages for bta_ag_api functions
Summary:
* Do not use bta_sys_sendmsg(BT_HDR) in bta/ag, use base::Bind instead
* Do not use BT_HDR in bta/ag
* Do not do memcpy during thread switch in bta/ag, instead, we use the
default copy constructor
Details:
* Currently, bta_ag_api functions use explicit messages to cross from
jni to bta thread. This adds unnecessary indirections that make it
hard to figure out which methods in bta actually get called
* Instead, base::Bind can bind to methods in bta directly without
putting parameters in an explicit struct. This greatly simplify our
code without breaking the current threading model
* With base:Bind, we no longer rely on bta_sys_sendmsg(BT_HDR) to send
event across threads. We can therefore get rid of BT_HDR in all
sub-types of tBTA_AG_DATA. Instead of using BT_HDR->layer_specific
flag to pass down handle IDs, we pass down handle ID directly,
resulting in less confusion on the actual meaning of data

SDP: Increase heap buffer size used for A2DP/AVRC
This buffer is used to save the attributes parsed from the SDP response
transferred from a peer device.
In Android O, SDP fails sometimes due to full memory from SDP DB.
The reason of this shortage seems to be the increasing of allocated
memory for tSDP_DISC_ATTR.
Android N uses a 32-bit bluetooth lib and 4 bytes of memory for
pointers.
In total, 12 bytes are used for tSDP_DISC_ATTR
Android O uses a 64-bit bluetooth lib and 8 bytes of memory for
pointers.
Now, 24 bytes are used for tSDP_DISC_ATTR.
To match this increase of memory consumption, We need to double the heap
buffer size. (from 1000 to 2000)
