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.

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.

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.

Wrapping MediaCodec ISEs in MediaCodecDecoderException lets us attach
MediaCodecInfo, which contains lots of useful information such as the
MediaCodec name, the codec capabilities, etc.

*** Original commit ***
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.

It's potentially confusing that this resets both position & limit, so
require callers to pass `limit` explicitly, or call setPosition(0)
if that's actually what they intended.
This makes enforcing the limit in an upcoming change slightly safer.
PiperOrigin-RevId: 323340485
This allows us to enforce the limit because the array can only be
reassigned through reset(byte[]) or reset(byte[], int) (which update
the limit)

This removes Supplier, Function and Predicate. Consumer is kept because
Guava doesn't have an equivalent (Java 8 does, but we can't use that
yet).

MP3 is last in the sniffing order now, so I think it's fine to do this
without worrying about impacting on other file types.
