Request to extend audio feeding time from BT

- Issue:
Recording from BT is blocked 15 sec. after recording begins.

- Solution:
By the policy of BT mic, the recording is blocked 15 sec. after begins.
It is because to save the battery of BT remote controller.
To resolve this issue, this patch adds API invocation to request extend
BT audio feeding. Every invocation, this API extends the recording time
by 5 sec. Through this change, BT mic will send the voice until
recording stop.
