Some methods marked as throwing DecoderQueryException actually
did not throw it. Switch to marking throws Exception
everywhere.

Relevant part of the spec:

This means multiple failures are all logged, instead of the test
stopping when the first assertion fails. Makes tests like this with
lots of independent assertions much easier to work with.

I limited the expect to a single assertCues() call, otherwise
the error message gets very long and is hard to read, but I
still think this is an improvement.

Cue's UNSET and null values should be used when the source data
doesn't specify *and* the spec doesn't provide a clear default.
In the WebVTT case, the defaults are clear, so we use them
explicitly.

The framework opus decoder discards some samples after a call to
flush(). Because we flush a decoder that is being retained across an
input format change, this means that the start of audio gets truncated
when transitioning to a new opus stream. See also
https://android.googlesource.com/platform/frameworks/av/+/refs/heads/android10-release/media/libstagefright/codecs/opus/dec/SoftOpus.cpp.

Avoid this by recreating opus decoders instead of flushing them. It
seems fine to do this for all opus decoders as reinitialization should
be cheap, OEM-provided implementations may also discard samples and
playback shouldn't be interrupted on reinitialization due to the
downstream AudioTrack buffer.

The nested ternary is quite hard to read imo, and I believe this is a
no-op change that captures the intent more clearly.

The demo app was using this via its dependency on the material library,
but it's preferable to list dependencies explicitly (otherwise the build
would break if we removed the material dependency).

This helps get HlsMediaPeriod off the blacklist.

Update it to throw if hasNext() is false, to match Java's Iterator
interface.

This also simplifies the null-checking annotations required

The leanback library doesn't know about non-square pixels. So if
we're playing content that uses non-square pixels, we need to adjust
the video dimensions that we provide to leanback such that it
renders the video with the correct aspect ratio.

Also remove it from all tests, these aren't covered by the null-checker

Use Float.NaN for Cue#DIMEN_UNSET

Float.MIN_VALUE is very close to zero:
"A constant holding the smallest positive nonzero value of type float"
https://developer.android.com/reference/java/lang/Float.html#MIN_VALUE

Float.NaN more clearly conveys this is an invalid number,
and will also more clearly carry over if we do maths on it a...

Prevents access of fields before initialization. Also set
remoteMediaClient in the constructor by using setRemoteMediaClient
instead of assigning the field directly, which will (if possible)
pull the state of the receiver in the constructor.
