If FM over A2Dp is disabled, we don't need to route FM audio to A2DP.
Hence do not register A2DP service listener if FM over A2DP is disabled.

FM registers two intent listener for headset removal. Because of the
intents recieved from both listeners, race condition happens. Even antenna
is connected to device, FM app shows antenna as disconnected.
Hence register one listener for headset removal.

when fm audio is routed to a2dp, then video is started
to play. fm will receive pause cmd, and call fmOperationsOff,
then call resetAudioRoute(). audio output will be changed to
wired headset. We should keep audio route unchanged.

this patch can fix below two issues.
1) after call ends, telephony will still play call end tone.
so we should not resume fm immediately after call ends.
2) if fm has been paused and abandoned audiofocus because
other video app starts to play and sends pause cmd to fm,
then after call ends, we should not resume fm automatically.

we should only resmue fm after fm gains audio focus.

disable fm completes, fm enable fails. Hence wait for disable fm

On Audio focus loss, slave device, FM, keeps on sending packets to
master device, audio manager, even master is disconnected to slave
and slave's buffer overflowed after some time. Due to this, on Audio
focus gain, slave don't send packets to master. Hence no audio for
FM. Reset slimbus data port to overcome this situation.

In dequeue_fm_tx_cmd function, there is race condition happened between
command credits decrement and event received for command sent. After
sending command to SoC, event received immediately and processed before
it decrement the command credits, hence command credits become zero and

1) wired headset is plugin, a2dp is connected, fm is on =>
2) plugout wired headset, then disconnect a2dp =>
3) will not control alarm/ring volume via +/- button
reason: after plugout wired headset, then disconnect a2dp at last,
configureAudioDataPath(true) will be called and AudioSystem.DEVICE_OUT_FM
will be set to DEVICE_STATE_AVAILABLE. Then we can only control
media volume via +/- button.

Whenever call is getting ended, FM requests Audio Focus
before Telecom abandons it, There is delay for about 50ms.
Now, with this change FMRadio will wait for 300 ms to get the
focus back from the telecom.

Generally, both FM and Playing Tone for call end are dependent on
call state changed, so the progress of receiving is in parallel.
But due FM gets callback via remote calling, it is always slower
than Telecom. Currently for N, the audio_focus_release had been
moved into state machine (in work thread), so the issue becomes
easy to see.

We cannot serial the call_status_change and the audio_focus_release.
Because Telecom also need to wait DISCONNECTED to paly tone, after
completed to abandon it.
So need FM needs to handle it by waiting for some more time.
