stagefright: Clear mNoMoreOutputData flag during seeking

For some 3rd party players, stop won't be called when playing
to the end. If seeking happens after that, we need to clear
this flag to make it be ready for subsequence data flow.

Track volume should be maintained even if track is restored

If track is restored when it set its volume to a non-unity value (such as mute),
the volume was forced to unity again.  Now, the previous volume is restored.

audio_policy: Fix for mute count mismatch for sonification strategy

- Sometime ring tone is not heard while in MT call

- During call mode, primary output ringtone/alarm stream mute count
  is incremented on startOutput and decremented on stopoutput
  for all Output requests.
    This is resulting side effect if stop output for non-primary outputs
  called, when no active streams available on primary output(mute count
  will not decrement)

- Add requested output check on start & stop output before calling
  handleIncallSonification API

audio_policy : Fix for incorrect input device selection

BLUETOOTH_SCO_HEADSET is not avaibale in input devices list
for recording usecases. Add the same to allow VOIP applications
to select BLUETOOTH_SCO_HEADSET as input device when
BT is connected.

stagefright: httplive: Fix deadlock for low duration clips

PlaylistFetcher buffers up to 3 * target-duration bytes of data,
but if a stream is slow (ie due to bad network conditions), a
buffer threshold of 10s is used to resume playback. This results
in an indefinite freeze as PlaylistFetcher has stopped buffering
before this threshold. Reduce the 10s threshold to be more in-sync
with PlaylistFetcher's buffering size.

stagefright: httplive: Reduce memcpy calls for chunked content

Streams using http chunking will not report the segment's total
content-length. In this case, a 64k buffer is allocated and is
increased by 32k each time the buffer is filled again. For high
bitrate content, this can lead to a large number of copies that
affect the HLS framework delay. Increase fetchFile buffer size
exponentially by 50% or at least 32k instead of by 32k each time
to reduce the number of memcpy calls.

Example for a chunked 6 MB 1080p segment (ie ~3s):
Adding 32k:
190 copies with 572.97 MB copied

Increasing by 50%:
12 copies with 16.09 MB copied

Added support for YEAR metadata key from VorbisComments

The OggExtractor wasn't extracting the YEAR key when the metadata in
the file was parsed. The YEAR key is now extracted when the file
metadata is parsed.
