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.

This will simplify the addition of nullness annotations.

- 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.

Also include 5G-NSA estimates and update code to use immutable
structures to prevent external updates by the app.

1) As we don't display metadata (title) removed titlebar.
2) Removed exo_ic_{forward,rewind}_30.xml which are not used.

StyledLayoutManager#isFullyVisibility() was wrong and
so hiding/showing logic didn't work properly.

Codec bypass is now enabled for all formats
audio track supports.

PiperOrigin-RevId: 324987842

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.

It seems generally useful to have access to the decoder in
getOutputFormat. We're currently working around lack of access
by using member variables in the concrete audio extension
renderers. In the case of the Ffmpeg extension, holding a
reference to the decoder is preventing it from being garbage
collected when the decoder is released by the base class.

After discarding upstream we shouldn't reuse the extractor from the
(newly) last media chunk because the extractor may have been reused
already by the discarded chunks.

Also add an assertion to SampleQueue that prevents the hard-to-detect
failure mode of overlapping sample byte ranges.

The media id defaults to the URI that shouldn't be logged to logcat.

The working of libOpus is different from ffmpeg. With ffmpeg, the decoder can
be configured to output floating point PCM. While in libOpus, floating samples
are acquired by calling a different function. This is the reason the new JNI
functions and the logic in OpusDecoder/LibopusAudioRenderer is added to
support float output.

Demo app supports clip start/end points and demonstrates manual
ad insertions.

This callback was not notified before, which could theoretically lead to ad
loading timing out. In practice it doesn't currently happen because the timeout
appears to start when the ad cue point is reached, not when loadAd is called.

We notify onLoaded when the ad media period is prepared (for HTML5 the
recommendation is to notify on the HTMLMediaElement 'canplay' event, which this
roughly corresponds to).

Issue: #7244 added this feature to HLS. This change is the exact copy
in ChunkSampleStream to add the same support to the other adaptive
formats.

Note that ChunkSampleStream doesn't support slicing, so we can't cancel
a read-from chunk, and we need to prevent reading into an already
canceled chunk load so that the chunk can be automatically discarded
after the cancelation.
