Stagefright: use MediaCodec in async mode for recording
Async mode reduces the number of messages posted between
MediaCodec and MediaCodecSource. This reduces thread
wakeups and helps reduce CPU utilization.

MediaCodecSource: stop puller from caller's thread instead of looper
Currently CameraSource/AudioSource's stop() and read() are both called
from the puller's looper. This works if source operates normally (i.e.
read() returns regularly before source is stopped), as the stop() will
eventually be handled by the looper. However, if for some reason the
source hang, it will get stuck in read(), and the stop() will never
be processed, which could lead to ANR (in addition to the source hang).
We need to move the source's stop out of the puller's looper. It also
can't be on MediaCodecSource's looper, because the source's stop
synchrounously waits for all outstanding buffers to return, these
are only returned when MediaCodecSource's looper processes the buffer.
This change moves the stop to MediaCodecSource::stop, after encoder
is shutdown.
