Note: End to end emsg support is still non-functional.
There's some additional plumbing that still needs to
be done.

- Parse EMSG leaf atoms during FMP4 extraction (although
currently they're just discarded).
- Add readNullTerminatedString to ParsableByteArray.

When CEA-608 is embedded in MP4 each packet consists of
cc_data_1 and cc_data_2 only. The marker_bits, cc_valid
and cc_type are implicit. As a result playback of CEA-608
embedded in MP4 broke when we started passing the extra
byte for the TS case (and adjusted the decoder to assume
the byte was present).
This change introduces a special mimeType for the case
where the byte is implicit (!). An alternative option
was to insert the extra byte every 2 bytes in the MP4
extractor, but this is really quite fiddly to get right.
Also made the loops in the 608/708 decoders robust against
input of the wrong length.

ReusableBufferedOutputStream is a subclass of BufferedOutputStream with a reset(OutputStream) that allows an instance to be re-used with another underlying output stream.

Clean up AtomicFile and make it return a custom FileOutputStream
for writing which handles IOException automatically during write
operations.
It also syncs the file descriptor and deletes the backup file on
close() call. This fixes the order of flush and close operations
when the fileoutputstream is wrapped by another OutputStream.

This CL adds a SpliceInfoDecoder for the most common SCTE35 commands for splcing.
So far, it only includes TransportStreams, but porting it to HLS and DASH should be
fairly easy.

A VOD-style period in a dynamic manifest would result in a NullPointerException.
Also fix another issue in which an unrecognized mime type would also result in
NullPointerException.

Note that actually handling CEA-708 is not yet implemented,
and so this is a no-op change from a behavior point of view.

All of the classes in the text.eia608 package have been moved to
text.cea, and renamed with the "cea" prefix instead of "eia". All of
the buffering logic has been extracted from Cea608Decoder (formerly
Eia608Decoder) into the abstract CeaDecoder, which Cea608Decoder
extends. Cea608Decoder also now expects a 3-byte sample (i.e. the
entire cc_data_pkt instead of just the cc_data_1 and cc_data_2 bytes).
Classes like RawCcExtractor and SeiReader, responsible for creating
these samples, have also been updated accordingly.
This change is a necessary precursor to adding support for multi
-channel CEA-608 and CEA-708 captions.

- Use a single constant for unset/unknown times across
all time bases. Note also that this moves away from
use of -1 for unset/unknown times in ms, which was a
bad choice (it might conflict with real times, such
as a time representing being just behind the start
of a live window).
- Add a few other unset constants, and use them.
- Fix some hardcoding of -1 where existing constants
should have been used.

Useful functionality promoted to core library:
1. Management of SurfaceHolder.Callback lifecycle
promoted to SimpleExoPlayer
2. Ability to determine whether audio/video tracks
exist but are all unsupported promoted to
MappingTrackSelector.TrackInfo
3. Read external storage permissions check promoted
to Util
4. SubtitleView given ability to act directly as a
TextRenderer.Output to remove layer of indirection
5. SubtitleView given ability to configure itself to
user's platform wide caption styling
6. KeyCompatibleMediaController promoted to library's
UI package.
Relocation of boring stuff:
1. ID3 frame logging moved to EventLogger.
