Allocate buffer for AV SDP in Stack
Remove buffer allocation in BTA while going for SDP before triggering
A2DP connection. This strategy is followed to address memory corruption
issues due to freeing of BTA buffer before SDP RSP call back is
triggered and access the freed buffer from there, leads to crash when
running Codemonicom tests.
The change allocates and frees buffer in stack.

Do not initiate SDP for incoming AVDTP connection
There are few instances when remote initiates L2CAP
channel for AVDTP signaling but keeps quite after that,
and later on timeout DUT goes for rest of the signalling
procedure but does sdp prior to the same.Few peer
devices deletes a2dp sink sdp record when there is an
ongoing connection, as a result sdp request fails and
DUT fails to proceed with signalling procedure and
connection setup fails.
This patch makes sure that DUT does not go for redundant
sdp request for AVDTP, provided remote has already
established L2cap connection for the same. SDP is done
explicitly only incase of outgoing AV connection.
This issue is seen with Nokia Es headset.

Refactor the Bluetooth timers
* Updated the alarm API:
- Existing API alarm_new() is modified to take an alarm name
as an argument.
- New API alarm_new_periodic() is used to create a periodic
alarm.
- Added new API alarm_is_scheduled() to test whether an alarm is
scheduled.
- Existing API alarm_set_periodic() is removed: a periodic
alarm is created by alarm_new_periodic().
- Added new API alarm_set_on_queue() to set an alarm whose
callback is executed on a specific queue.
- Added new API alarm_register_processing_queue() and
alarm_unregister_processing_queue() to register/unregister
a queue and the corresponding thread for alarm processing.
- Added corresponding unit tests.
* Updated the alarm internals:
- Added alarm_info_t for collecting alarm-related information
and statistics.
- Collect and store alarm-related statistics into alarm_info_t
per alarm.
- Include the alarm-related statistics and info into the native
dumpsys output for Bluetooth.
- Once an alarm expires, the alarm execution is scheduled for
processing on another internal alarm-specific thread, not
on the thread that is maintaining the alarms.
- Implemented callback execution ordering guarantee among
timers on the same thread with exactly same timeout values.
* Refactor some of the usage of alarm_set() and simplify the
code by using alarm_set_on_queue() instead.
* Removed the non_repeating timers wrapper, and use directly
the alarm mechanism / API.
* Refactored all timer_entry_t timers and replaced them with alarm_t
timers:
- Replaced the btu_start_timer() / btu_stop_timer() /
btu_start_quick_timer() / btu_stop_quick_timer() /
btu_oneshot_alarm() mechanism with alarm_set_on_queue() and
alarm_cancel()
- Removed the whole mechanism around the BTU_TTYPE_* timers.
* Fixed a bug when processing the GATT indication confirmation timer
expiration (timer tGATT_TCB.conf_timer: b/26610829).
* Renamed and/or split misc. timeout functions, fields, and timers
* Renamed time-related constants and changed the values from seconds
to milliseconds
* Replaced timer tAVDT_CCB.timer_entry with three mutually exclusive timers:
idle_ccb_timer, ret_ccb_timer, rsp_ccb_timer
The reason we are using three timers, is because in the original code
function avdt_ccb_chk_timer() used the timer type in its logic: it
would stop the timer only if the type is "idle".
* Removed btm_ble_timeout() and replaced it with multiple timeout
callback functions (per timer)
* Fix the actual value of the global constant BT_1SEC_TIMEOUT and
rename it to BT_1SEC_TIMEOUT_MS
* Removed btu_cb and associated timers and events, because they are
never used.
* Removed unused timers, functions, struct and declarations that are
not used / needed.

Support for A2DP Sink and Proper initialization of profiles
- Register SDP and SEP (Stream End Point) for the profile
whose init is called. We achieve this by making registration
api aware of profile id being called.
- Register A2DP Src + Avrcp Target + Avrcp Controller. We need
to support Absolute Volume as well, so Avrcp Controller is
required here.
- Register A2DP Sink + Avrcp Controller. In this case we do not
support absolute volume. Support would be added in AVRCP
controller change
- Adapter property is updated with profile ID for which init is
called.This is required to make changes in btService for Profile
initialization
- Start listening for incoming AVRCP connection if we have
only AVRCP Controller
- Update default peer_features based on feature mask. In case
of incoming AVRCP connection, SDP will be done later.
In such a scenario default peer features sent to btif should
be based on features-set selected during initialization.
- Drop Control, Meta and Browse commands when TG is not up.
- Not to call AVRCP app callbacks when mentioned service is down.
- Close audio socket on suspend
A2DP Sink: Support for AudioTrack
- implemetation for audiotrack to take care of audio rendering
- support for audio focus state in bluedroid
Bluetooth: Support for Avrcp 1.3 Controller
- support for SDP registration
- support for sending vendor dependant commands
- support for abs vol
- support for receiving vendor dependant response
- serialization of connection and rc_features callback
Avrcp_Ctrl: handling of commands and events for AVRCP Controller
- support of parsing cmd and event pdus
- timeout handling

GKI cleanup - Moved struct TIMER_LIST_ENT to OSI
* Moved struct TIMER_LIST_ENT to file osi/include/non_repeating_timer.h
and renamed it to timer_entry_t
NOTE: This is a short-term solution. timer_entry_t should be
removed, and its usage everywhere should be replaced by
struct non_repeating_timer_t .
* Renamed TIMER_CBACK to timer_callback_t
* Renamed TIMER_PARAM_TYPE to timer_param_t

GKI cleanup - Moved GKI_get_os_tick_count() to OSI
* Renamed function GKI_get_os_tick_count() to time_get_os_boottime_ms()
and moved it to the OSI module: to the new file osi/src/time.c .
The corresponding header file is osi/include/time.h
* Added unit tests for function time_get_os_boottime_ms() in file
osi/test/time_test.cpp
* Removed "osi/include" from the list of paths to search for include
files. This is needed, because file name collision of "time.h"
in osi/include and the system <time.h>
