bluez a2dp - use a sensible write timeout

The 500 msec write timeout is extremely optimistic, a 1000 msec
timeout is closer to reality.

bluez a2dp - fix wait_for_start() spurious wakeup

When waiting on a condition is is possble to receive spurious
wake ups. Deal with this in wait_for_start().

bluez a2dp - fix wait_for_start() synchronization

On entry to wait_for_start() it's possible we are in state
A2DP_STATE_NONE if a2dp_thread() has not completed bluetooth_init().
Also, we call the pthread_mutex_*() functions more frequently than
we really need to.

Move the mutex locking outside the loop and let condition wait
take care of the locking. Also move the A2DP_STATE_NONE check
below the condition wait so we can be sure the state machine
has been poked before we test it.

bluez a2dp - destroy thread attr after thread create

Pthread resources may be used by the thread attributes object.
We should destroy this after thread creation.

bluez a2dp - destroy thread resources at exit

The dynamically created pthread mutex and condition variables
consume pthread resources. They should be destroyed prior to
freeing the structure containing them.

bluez a2dp - fix a2dp_thread() spurious wakeup

When waiting on a condition is is possble to receive spurious
wake ups. Use the fact that when we poke the state machine the
command must have changed to deal with this.

bluez a2dp - fix state machine synchronization

Using a worker thread implementation for A2DP means that if we don't
have some way to syncroniize state transitions we can get overlap of
requested command functions or lost signals. In order for the A2DP
state machine to function each command operation must complete before
the next is initiated or we will get errors caused by these out of
sequence commands. And if we signal the thread when it is not waiting
on the condition the signal will be missed.

This could be partly resolved by implementing a queue but then there
is an overhead with also implementing a wait mechamism for state
transitions. It's much easier and simpler to just hold the mutex
during command processing which also deals with the lost signals issue.
This may well not achieve the original goal of the worker thread
implementation but neither would a queue implementation. It looks
like this is just the way things are!

bluez a2dp - syncronize worker thread start

There is an order of execution assumption made when starting the
a2dp worker thread. Add an additional condition variable to allow
us to make sure we have reached the thread_wait condition wait
before returning from a2dp_init().

liba2dp: Fix timeout computation in wait_for_start()

Also increase a2dp_write timeout from 100ms to 500 ms
to avoid losing the first fraction of a second of a song
when streaming starts.

Add bccmd tool to makefile, conditional on board bluetooth type

I think bcsp support needs to be added to hciattach too.

AI 145972: am: CL 145785 Don't close the A2DP data socket on data error - prevents mediaserver from wedging on A2DP device poweroff.
This prevents a race that occurs when an A2DP headset is powered down. If the data socket closes itself then mediaserver tries to recover the stream, while the control path in hcid tries to cleanup the disconnected stream. hcid cant handle this and wedges mediaserver.
Instead let the control path code trigger all the cleanup (including eventually closing the data socket through bluetooth_close() or bluetooth_stop()).
