- Remove manifest argument from callbacks of Player.EventListener and
  SourceInfoRefreshListener. Instead make it accessible through
  Player.getCurrentManifest() and Timeline.Window.manifest.
- Fix all MediaSource implementation to include the manifest in the
  Timeline instead of passing it to the SourceInfoRefreshListener.
- Refactor ExoPlayerTestRunner, FakeTimeline, FakeMediaSource to
  reflect these changes and make tests pass.

Sending MESSAGE_PREPARE_SOURCE should happen last in the constructor.
It was previously happening before initialization finished (and in
particular before pendingMediaPeriods was instantiated).

We currently use an alpha version which allowed us to access new threading
features. The stable version of this has been released now and we can
switch back.

We currently handle most the control code logic after handling special
characters. This includes filtering out repeated control codes and checking
for the correct channel. As the special character sets are control codes as well,
these checks should happen before parsing the characters.

- Explicitly specify HTTP_METHOD_POST (previously this was
  implicit as a result of the body data being non-null)
- Use null when there's no body data (it's converted to
  null inside of the DataSpec constructor anyway)

Currently, we sometimes apply new playback parameters directly and sometimes
through the list of playbackParameterCheckpoints. Only when using the checkpoints,
we also reset the offset and corresponding position for speedup position
calculation. However, these offsets need to be changed in all cases to prevent
calculation errors during speedup calculation[1].

This change channels all playback parameters changes through the checkpoints to
ensure the offsets get updated accordingly. This fixes an issue introduced in
https://github.com/google/ExoPlayer/commit/31911ca54a13b0003d6cf902b95c2ed445afa930.

[1] - The speed up is calculated using the ratio of input and output bytes in
SonicAudioProcessor.scaleDurationForSpeedUp. Whenever we set new playback
parameters to the audio processor these two counts are reset. If we don't reset
the offsets too, the scaled timestamp can be a large value compared to the input
and output bytes causing massive inaccuracies (like the +20 seconds in the
linked issue).

This gives a caller greater confidence that the methods have no
side effects, and remove any nullness issues with these methods
accessing @Nullable member variables.

- Inline some unnecessarily split out helper methods
- Clear ExtractorInput from FlacDecoderJni data after usage
- Clean up exception handling for StreamInfo decode failures

The masking logic for unprepared MediaSources is currently part of
ConcatanatingMediaSource. Moving it to its own class nicely separates the
code responsibilities and allows reuse.

1. Only output video starting from a keyframe
2. When calculating the timestamp offset to adjust live streams to start
   at t=0, use the timestamp of the first tag from which a sample is actually
   output, rather than just the first audio/video tag. The test streams in
   the referenced GitHub issue start with a video tag whose packet type is
   AVC_PACKET_TYPE_SEQUENCE_HEADER (i.e. does not contain a sample) and whose
   timestamp is set to 0 (i.e. isn't set). The timestamp is set correctly on
   tags that from which a sample is actually output.

The total window and period count, as well as the period offset for each holder
are not actually needed and can be removed.

Also added a TODO to remove two other variables if possible.
