Added missing A2DP priority on java alarm service
Running GKI timer engine via JAVA alarm service was causing severe
timer preemption at times which affects A2DP media task timer. This in
turn was stressing the compensation logic towards UIPC resulting in
very bursty reads of up to 40 UIPC frames at a time. This led to
instabilities on the UIPC pipe and trickled upwards in audio framework.
Inclusion of java alarm thread in A2DP high priority thread list results
in a much smoother data flow for entire A2DP data path and improved
audio quality.

Raise A2DP threat priority to avoid music breaks
* Ensure all a2dp audiopath threads are configured to high
priority when actively streaming.
* For now set bt hc worker thread always to URGENT_AUDIO
until new thread api can adjust thread priority dynamically.

increase the bluetooth task priority when start a2dp.
change the BT task priority based on audio play state.
increase the BT task priority to ANDROID_PRIORITY_URGENT_AUDIO
,when start ad2p audio playing.
to better prevent CPU premption by other process/task(UI).
restore the BT task priority when stop a2dp audio playing.

Add macro UNUSED() to bt_utils.h
Also include bt_utils.h in some other header files commonly
included by some subsystems.

a2dp media packet sent too slow, which cause packet overflow.
the error message: btif_media_aa_prep_2_send congestion buf count 24
The reason is we increase all bluedroid thread related TX data path priority:
media, timer, BTU and HCI_WORKER, but we didn't increase the RX data path
priority: userial_read_thread. If the RX thread is blocked, it will also
affect TX, because the HCI have flow control, we need receive HCI Number of
Completed Packets Events to continue send packet to the controller.
If we HCI complete Packets Event packets is blocked, the HCI flow control
will block the HCI packet trnasmission until we get HCI complete packets
event to know how many buffer is available in the controller.
I tested with a chrysler CIP/VP4 carkit which show this error message,
After I apply this fix, I can't reproduce this problem any more.
This look like good fix for this issue.
