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.

Updated Gradle, Compile and Build Tools Version

Add Flags to MP3 Extractor to force CBR Seeker

Added flags to the mp3 extractor to control behavior of the extractor. Added FLAG_ENABLE_CONSTANT_BITRATE_SEEKING to let the extractor know that the CBR seeker is desired in the case where the seeker has determine the track is not seekable For example, in the case where the track has a Xing Header but no content table.

InitializationChunk calls init(null). When the initialization and index data is separate they need to
be loaded separately which results to two init(null) calls.

Make DrmSessionException constructor public to enable creating custom DrmSessionManager implementations.

I've also added a TODO to not even bother trying to parse CEA from
SEI NAL units if they're fully or partially encrypted, which it's
possible to determine in the FMP4 extractor.

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.

- It's always fine to prefer the manifest drm init data. In
  DASH we always do this anyway. In SS the manifest and sample
  formats are identical.
- Optimized the case where the manifest and sample formats are
  identical by avoiding the format copy.
