At the end of playback, BufferProcessors need to be drained to process all
remaining data, then the output needs to be written to the AudioTrack before
stop() is called.

This CL allows passing multiple formats describing CC channels to the
TS payload reader factory. As a simple usecase, ATSC can expose both
608 channels by passing a two element list with the corresponding
accessibility channels. The HLS media source can construct this list
from the EXT-X-MEDIA:TYPE="CLOSED-CAPTIONS" tags, including language
and selection flags. The interface extends without modification to
708.
Pending work:
* Multiple CC channels in HLS.
* caption_service_descriptor parsing for overriding the user's selection.
* 708 support in SEI reader.

SoftAAC2 would cause an exception to be thrown from
dequeueOutputBuffer/releaseOutputBuffer after queueing an end-of-stream buffer
for certain streams.
The bug was introduced in L and fixed in L MR1, so the workaround is targeted to
API 21.

The outputBuffer is not necessarily empty after a flush, so the assertion could
fail in normal usage. The assertion can just be removed as the output buffer is
rewritten in full on every call to handleBuffer.

DASH we always do this anyway. In SS the manifest and sample
formats are identical.

This allows binding by track type in ChunkExtractorWrapper, which
allows the EMSG and 608 tracks to be enabled on FragmentedMp4Extractor
in DefaultDashChunkSource. ChunkExtractorWrapper currently binds these
to DummyTrackOutputs.
Note: I wanted to pass the mimeType instead, since it's a more specific,
but unfortunately there's at least one place where it's not known at the
point of invoking track() (FlvExtractor).

The first issue occurs when we attempt to process a DtvCcPacket that hasn't been completely filled. In this case we attempted to extract data beyond the length of the packet, instead of dropping the packet as we should have. The other issue occurs when we encountered an invalid cc_data_pkt. In that case we were finalizing the entire DtvCcPacket, instead of just ignoring that particular cc_data_pkt as we should have.

* Prevents calling endTracks() before all PMTs have been
processed.
* Adds a unique ID to the format of each track. This allows
the track selector to identify which track belongs to
each program. The format of each id is
"<program number>/<track output id>".
Note: This CL will break malformed TS files whose PAT
declares more PMTs than it actually contains, which
previously were supported. This does not apply for HLS
mode.

Instead of clearing the DECODE_ONLY flag for all input buffers in TextRenderer (i.e. for all caption types), we now only clear it on the output buffer in SimpleSubtitleDecoder. The number if input buffers in CeaDecoder has also been increased to reduce the delay before captions appear for playback sessions that start far ahead into the content.

- Fix to use different track ids for EMSG + CEA608, so they can
both be enabled at once.
- Tweaked extractor to output formats prior to endTracks() when
parsing the initial moov box. This makes it easier to handle
multiple tracks through the chunk package. It may or may not
be made a requirement (it's already true for the MKV extractor).

use pixel count as a tie breaker if pixel counts are known
