This fixes DefaultDrmSessionManager so it can be used by a new Player
instance (by nulling out its reference to the playback thread, which is
unique per-Player instance). This only works if the
DefaultDrmSessionManager is 'fully released' before being used by the
second Player instance, meaning that the reference count of the manager
and all its sessions is zero.

I think this has been broken since https://github.com/google/ExoPlayer/commit/617267bfcf20c500fb4a3cfdff7104e4d88261a7 (which was trying to fix
the same problem).

This change initializes `rootDir` to always be the current project (i.e. ExoPlayer)
directory. From the [Gradle docs](https://docs.gradle.org/current/userguide/working_with_files.html#sec:single_file_paths):
> What happens in the case of multi-project builds? The file() method
> will always turn relative paths into paths that are relative to the
> current project directory, which may be a child project.

We can also then remove exoplayerRoot completely and simplify the local
dependency instructions.

SubtitleExtractor is using IndexSeekMap with only one position to
indicate that its output is seekable. SubtitleExtractor is keeping Cues
in memory anyway so more seek points are not needed. SubtitleExtractor
gets notified about seek occurrence through seek() method. Inside that
method extractor saves seekTimeUs, and on the next call to read()
extractor outputs all cues that should be displayed at this time and
later.

Some server will send partial URIs in the RTP-Info header, while the RTSP spec

The C2 MP3 decoder produces an extra output buffer when draining after
end-of-stream is queued. This output buffer has a later timestamp than the last
queued input buffer so we need to calculate its timestamp to detect a stream
change in the correct position.

Before this CL we used the original input buffer timestamp as the largest
queued timestamp, which caused the stream change to be detected at the correct
position because the original input buffer timestamp was slightly larger than
the actual last output buffer timestamp. After this change we use exact
calculated timestamp as the largest queued timestamp. I manually verified
gapless continues to work on a device using the C2 MP3 decoder by comparing
output of the MP3 gapless and MP3 gapless stripped playlists in the demo app,
and that the last buffer timestamp now matches.

The current detection logic checks that the two byte terminator starts
at an even position in the ID3 data, where-as it should check that it
starts at an even position relative to the start of the string.

Simplifies the SubtitleExtractor implementation. Makes the extractor
more aligned with the Extractor interface documentation by removing
STATE_DECODING in which extractor was doing nothing in term of input
and output while returning RESULT_CONTINUE at the same time.

C should only hold constants.

Also resolve the TODO in getErrorCodeForMediaDrmErrorCode(), and
annotate the deprecated methods with Error Prone's @InlineMe to
facilitate automated refactoring of callers.

This typically happens if there's a discontinuity in the stream.
It's better to say we don't know, than it is to return a negative
position.

This CL contains integration of the ExoplayerCuesDecoder and the
SubtitleExtractor with the player. The SubtitleExtractor is integrated
inside the DefaultMediaSourceFactory. The flag was added to the
state of the DefaultMediaSourceFactory to let user decide between the
ProgressiveMediaSource and the SingleSampleMediaSource as a source for
subtitles. Choosing the ProgressiveMediaSource will cause data to flow
through the SubtitleExtractor and eventually the ExoplayerCuesDecoder.

Empty buffer with flag C.BUFFER_FLAG_END_OF_STREAM is send at the end
of the stream. Handling that flag properly is necessary to make the
ExoplayerCuesDecoder work properly with components like TextRenderer.
