I'm going to introduce an EmptySampleStream that will be used in
some cases in conjunction as part of 608/EMSG support. This change
avoids EmptySampleStream having to provide a dummy format.

This allows the user to interpret PTSs in the playback timebase.

This is no longer needed as MetadataDecoderFactory
figures out which decoder should be used.

This is analogous to what we do for text/subtitles, and
adds support for playlists where the type of metadata
changes from one playlist item to the next.

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

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.

One issue with the previous implementation was that
isUnsynchronized would not be set back to false if
previously set to true and if the next header has
majorVersion >= 4. In general, having the decoder be
stateless is clearer (and thread safe, albeit that
this property is not required).
- Lots of misc cleanup
- Remove GaplessInfo from Metadata. IMO it doesn't quite belong there,
and means it ends up being represented twice inside Format.
- Note: Changes untested, but will be tested in due course!
Also inline a few methods/classes where they can be made
private and therefore be removed from the public API.

- Invoked --> Called
- Gets --> Returns
- "True if X. False otherwise." --> "Whether X."
- Removed some @returns where the Javadoc is in "Returns X" form

In V1 we received complaints that Renderer was too locked down.
In particular, it wasn't possible to implement a Renderer that
wrapped another Renderer, since most of the methods were package
private and final (e.g. enable).
This change defines Renderer as a proper interface, removing
this limitation. A method-reordering-only change will follow
this one, to get things into a nice consistent/sane order in
each of the Renderer classes.

1. Rename "extensions" package to "decoder". It's used by both
text and (should be used by) metadata, so it's no longer just
for extensions.
2. Move Buffer objects move into the decoder package.
3. Rename SubtitleParser and MetadataParser to SubtitleDecoder
and MetadataDecoder respectively, since they extend Decoder.
Ditto for all subclasses.
4. Subtitle and Metadata decoders now throw their own exception
types rather than ParserException.
5. Move MediaCodec classes into a mediacodec package, with the
exception of the concrete audio and video renderers.
6. Create an audio package to hold the two audio renderer classes
plus related util classes.
7. Create a video package to hold the one video renderer class
plus related util classes.
After this change the following nice properties hold:
1. Want a video renderer? Look in the video package. Ditto for
audio, text and metadata.
2. All TrackRenderer implementations use a decoder of some kind
to decode buffers received from the source, so we have
consistent terminology there.

It doesn't look like TrackSelectionPolicy is going to be
useful other than with DefaultTrackSelector, and it's kinda
confusing dealing with both "selector" and "policy"
terminology. This change does the following:
DefaultTrackSelector -> selector.MappingTrackSelector
DefaultTrackSelectionPolicy -> selector.DefaultTrackSelector
TrackSelectionPolicy -> [deleted]

Also addded result constants to C to remove the dependency
on TrackStream from extractor.DefaultTrackOutput.

- The package is renamed to avoid conflicts with v1, should any
app wish to include both v1 and v2 for a period of time. This is
similar to the approach used by some other open source projects
(e.g. okhttp).
- Copyright year is updated everywhere for completeness.
