If volume button pressed while call is ringing, FM receives AUDIOFOCUS.
On call termination, FM don't resume, as FM already received
AUDIOFOCUS and don't resume FM on call termination.
Hence turn on FM when telephony CALL_IDLE_STATE intent received.

On call disconnection, AUDIOFOCUS_GAIN received before telephony state
intent and telephony state update happens after audio focus gain. Hence
FM turn on won't happen.
Turn on FM if telephony intent received or rety once after
100ms.

After sending enable request, wait for enable event callback to
complete.
If we configure audio path before enable receiver done, audio path
won't configure properly, hence no audio will be heard.

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.

On SSR, we receive HW_ERR_EVENT,we set lib_running variable to 0.
Because of this, hci tx and monitor thread exits before cleanup or exit
happens, causing RX thread to be blocked on cond_wait and failure
happens.
Hence not setting variable during event read.

Check if variable is null before making a call to avoid the null pointer
exception.

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.
