AudioTrack.setPlaybackParams can be used to adjust playback speed.
This is preferable to application-level speed adjustment (currently
implemented in ExoPlayer) from API 23 because the speed change
occurs in the mixer, which means that the audio track buffer doesn't
need to drain out before the speed adjustment takes effect.

formatSupport is a 2-dimensional int array but it's documented as
being indexed by 3 things. This seems to be a copy-paste mistake in
e97b8347eb
selectAllTracks() takes a 3-dimensional array with the same
3-indexed documentation, which makes sense there.
Also rename formatSupports -> formatSupport for consistency.

Use a dedicated boolean to track if we've notified the current surface,
rather than re-using rendereredFirstFrameAfterReset.

Find sbgp and sgpd boxes with grouping_type == seig in the case they don't
come first. Previoulsy we would only find them if they came first.

Pass startPositionUs into Renderer.replaceStream
Plumb this down into BaseRenderer.onStreamChanged and use it when
deciding whether to render the first frame of a new period.

- Attach types for placeholder sessions. If a placeholder session will be
attached and a downstream renderer doesn't know what to do with it, then
this attachment is necessary to correctly determine that the renderer
does not support the track.
- Attach types to sample formats. Without this, if playback fails due to
a CryptoException, the ExoPlaybackException that gets thrown spuriously
indicates that the format's DRM type was not supported.

Having both in the trun box is not allowed (see section section 8.8.8.1
of ISO/IEC 14496-12:2015) but this CL makes the code more robust in case
this happens. Before this change, the first sample flag was not read,
making subsequent reads incorrect.

The sniffer sniffs boxes at the start of the file to try and determine
whether the file is fragmented. However, if the file is extremely short
then it's possible that sniffing will try and read beyond the end of
the file, resulting i EOFException being thrown.
In general it's OK for sniffing to throw EOFException if the file is
not of the correct type. The problem in this case is that EOFException
can be thrown for an actual MP4 file, due to the sniffer continuing up
sniff atoms up to bytesToSearch in case the file is fragmented.

The term "passthrough" was heavily overloaded. For clarity, split most
of its usage to different terms:
* codec "bypass": no MediaCodec is used
* "direct playback": no decoding occurs (but decryption may or may not)
* "decrypt only codec": a MediaCodec used only to decrypt, not decode
* "offload": playback to an offload AudioTrack.
* "passthrough" is now only used in the sense of playing encoded audio
* to a non offload AudioTrack.

We are not able to associate a codecs attribute to an EXT-X-MEDIA tag if
there is no variant with a matching AUDIO GROUP-ID. Lack of codecs string
prevents chunkless preparation from determining the track type.
