Note on UnknownNull: Where there exists a generically typed
base class and both null and non-null types are permitted,
we need to clear the default non-null that's otherwise
propagated everywhere. This then lets the nullness of the
type work properly.

CryptoInfo.iv length is always 16. When the actual initialization vector
is shorter, zero out the trailing bytes.

Previously, the input buffer accessUnit count
was passed as the output of the audio processors
which did not make sense as the processors can
split buffers.

This patch passes the access unit count through a
member variable.

Seems like it belongs here.

This is closer to how our actual renderers look like and allows tests
to use a similar logic to show/suppress the first frame in follow-up changes.

We will eventually remove the workaround from ExoPlayerImplInternal
added in
https://github.com/google/ExoPlayer/commit/b84bde025258e7307c52eaf6bbe58157d788aa06
and replace it by an error that gets thrown if the LoadControl behaves
badly.

This avoids the issue of whether it is defined behaviour to cast an
arbitrary int (or even intptr_t) value to a void* pointer. This is the
original approach used before commit 0915998a.

Libgav1 recently added the ComputeFrameBufferInfo() and SetFrameBuffer()
helper functions for writing frame buffer callbacks. Using them
simplifies the Libgav1GetFrameBuffer() function.

Also resurrect the AlignTo16() function.

Previously that was implicit, it was the passthrough dance:
 - MimeTypes.getEncoding(inputFormat) did not
   implement RAW MIME, so it was returning INVALID_ENCODING for PCM
 - and allowPassthrough was returning
         MimeTypes.getEncoding() != INVALID_ENCODING
 - which was setting codecInfo.passthrough, and passthroughEnabled.

Thus Util.isEncodingPcm(encoding) is the opposite of
(MimeTypes.getEncoding(inputFormat) != C.ENCODING_INVALID)

This was rather implicit and brittle as anyone
could add support for audio/RAW in
MimeTypes.getEncoding and break PCM playback.

As a result make it explicit that allowPassthrough
must always return false in PCM.

API level >= 17 is guaranteed by shouldUseDummySurface returning true,
but Android Studio shows a warning anyway.

Modify TrackOutput.sampleData() to accept SampleDataReader instead of ExtractorInput. SampleDataReader supports only read and skip calls, which all sampleData() implementations already restrict themselves to.

Currently only one access unit can be written per
buffer write. This has been found to be power
inefficient in an offload situation.

This information isn't easily available to the player at the moment (or it
would need to revaluate this every time), so add it to MediaPeriodInfo similar
to the existing isLastInTimelinePeriod.

The player needs to know whether a MediaPeriod is the last in its Timeline
window if we want to add an option to pause at the end of a window.

Add fields in DecoderCounters for computing the average video frame
processing offset.

The MediaCodecVideoRenderer reports the video frame processing offset
and the demo app presents it on the debug information.

The transition in EPII happens based on the duration of the periods, not
the windows. So use this duration in case they are not the same.

Also make sure to send the message at duration-1 because the playback position
at the duration is technically already the first position in the next item.

This simplifies sending messages to the end of a stream. This was
already possible, but users needed to wait until the duration is known
before sending the message. This duration resolution can happen as part of the message position resolution.

This is a no-op change and just moves some duplicated logic into the
base class.
