This is less confusing than having audio processing functionality (e.g., playback
speed adjustment) just "not work" for some pieces of media.
If this change is merged, I will update #6749 to also track making DefaultAudioSink
intelligently enable/disable float output depending on how the audio processors are
configured.

It's incorrect to use an AudioFormat returned from AudioProcessor.configure
unless the AudioProcessor is active.

This is a no-op for DefaultAudioSink for now, because DefaultAudioSink
currently disables processing anyway if the input uses ENCODING_PCM_FLOAT.

If the start time of the edit falls within a sample, start from that
sample rather than the next one. This ensures playback can start from
the correct point if the sample is a keyframe, rather than having to
start from the next one.

The release_input_buffer callback will be called when the library
is done consuming an "input buffer". The buffer passed into
EnqueueFrame must be kept valid until this callback is called. If
frame parallel is false, then this callback can be nullptr (in
this case the buffer has to be kept valid until the next call to
DequeueFrame). If frame parallel is true, this callback cannot be
nullptr.

It's not clear why we're currently outputting the format in both init()
and consume() - it seems likely that this was accidentally introduced
in <unknown commit>
when we started outputting the format in consume() but didn't remove it
from init().
1. Have frame buffer callbacks return Libgav1StatusCode instead of int.
The 0 (success), -1 (failure) return value convention is less obvious.
Note: The callers of frame buffer callbacks,
BufferPool::OnFrameBufferSizeChanged() and YuvBuffer::Realloc(),
currently return bool, so more work is needed to propagate the frame
buffer callbacks' Libgav1StatusCode return value to the Decoder API.
2. Allow the FrameBufferSizeChangedCallback to be omitted if the frame
buffer size information is not useful to the application.
3. Remove the old (version 1) frame buffer callback API. Remove the
frame buffer callback adaptor.
frame_buffer2.h is renamed frame_buffer.h.
Libgav1FrameBuffer2 is renamed Libgav1FrameBuffer.
GetFrameBufferCallback2 and ReleaseFrameBufferCallback2 are renamed
GetFrameBufferCallback and ReleaseFrameBufferCallback.

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 0915998add5918214fa0282a69b50a159168a6d5.

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.

The new code in Libgav1GetFrameBuffer is copied from
libgav1/src/frame_buffer_callback_adaptor.cc. It may become libgav1
utility functions available to libgav1 clients in the future.
The Libgav1FrameBuffer struct in the old frame buffer callback API is
defined as follows:
typedef struct Libgav1FrameBuffer {
uint8_t* data[3];
size_t size[3];
void* private_data;
} Libgav1FrameBuffer;
Copy these three fields to the JniFrameBuffer class as private data
members and add the RawBuffer() and Id() getter methods.
The existing AlignTo16 function is replaced by the copied Align template
function.

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

This check is not needed because the FLAC specification does not
restrict the sample rate value and because the extension reads files
with other sample rates properly.

This condition is trying to detect when it might be necessary
to switch from a non-secure to a secure codec. This is not
possible if the DRM session is unchanged, unless a different
codec is required for some other reason (e.g., H264 -> H265),
which is anyway handled by canKeepCodec below.

Passing EXT-X-KEY DrmInitData through the FragmentedMp4Extractor
doesn't work for streams with key rotation, because an extractor
instance is used for multiple segments, but is only passed the
EXT-X-KEY DrmInitData corresponding to the first segment.
This change removes passing DrmInitData through the extractor,
and instead passes it via FormatAdjustingSampleQueue. This is
in-line with how manifest DrmInitData is handled during DASH
playbacks.

This is a nice-regardless improvement to SampleQueue, which will
likely to used to fix the referenced issue. It makes it possible
for SampleQueue subclasses to support dynamic changes to format
adjustment in a non-hacky way.

It doesn't seem worth keeping the cap, since the device
will presumably stop receiving major version updates at
some point anyway.
