Empirical testing in shows increased robustness.

- Workaround issue where video may freeze whilst audio continues
  on some devices that have entered bad states.
- Fix wrap-around for playbacks lasting more than 27 hours.

Apparently some servers don't like it, and in general it's
unnecessary to set the header for this case.

Refine logic for determining AudioTrack size.

- Target 4x the minimum specified by the framework.
- Impose a minimum duration (250ms).
- Impose a maximum duration (750ms, or the minimum
  specified by the framework if that's larger).

I've removed the ability to specify the multiplication
factor, since the underlying implementation is getting more
complicated, and we should really be able to figure this out
internally.

Issue: #214

Previously samples belonging to disabled tracks would just
accumulate in an arbitrarily long queue in TsExtractor. We
need to actively throw samples away from disabled tracks up
to the current playback position, so as to prevent this.

Issue: #174

I'm not sure exactly what the implications of this change are,
but I'd really hope that only one program in each stream is carrying
audio/video. For GoPro cameras, they expose the video stream in
the second program, for some reason.

Issue: #116

We've seen a few streams where this assertion fails. If you
just skip the packet, things appear to recover correctly in
all cases I've seen, so replacing failure with a warning.

If the server actually gives us a DEFLATE response, we
fail to handle it properly!

AudioTrack will mark 0-size buffers as consumed

This can happen in the first, non-codec-config output buffer
from MediaCodec, while decoding MP3 data.

This issue was discovered on Nexus 5's running both KitKat
Lollippop.

- Handle read returning NOTHING_READ for AC-3 streams.
- Remove extra checks for the audio track being initialized.
- Call isInitialized() instead of checking audioTrack != null.
