Not important, but when overriding a method that can return null,
it seems preferable to put @Override first, followed by what it's
overriding (which includes the @Nullable).

Also remove explicit @NonNull use in the core library. @NonNull is
propagated by default, so this is redundant.

This is one step toward following the google3's test naming convention.
See go/java-testing/getting_started#basic-test-template for details
why prefix test isn't necessary.

This CL is generated by following command
$ find -name '*Test.java' | xargs -I{} sed -i 's/^\ \ public\ void\ test\([A-Z]\)\(.*\)$/  public void \L\1\E\2/' {}

Because we now annotate not-null by default in ExoPlayer
library modules, we're seeing warnings in the demo apps where
we override a method and don't explicitly specify an equivalent
@NotNull annotation.

It's probably confusing to use not-null by default for the
demo apps, so this change uses @NonNull where necessary to fix
the warnings.

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.

All packages that are not in a test directory (or a demo app) should have
the non-null-by-default annotation. Add the remaining ones.

I had to expand the info that gets passed around a bit, so I could join up the container, base & text ruby nodes.

The part about leaving the pending trim start byte count unmodified
if the processor was just configured is not correct.

When copying CryptoInfo for asynchronous input buffer queueing,
re-use the destination CryptoInfo's arrays to avoid re-allocating
memory.

When common was split from core, this permission was moved
to common. However both modules need it.

 - Add Settings UI
 - Remove unnecessary values related to Full Mode
 - Remove unnecessary hierarchy in list item layout
 - Enable to select Playback Speed in Settings

Also changes:
   Keep Fullscreen UI when window focus changed in demo app

This was unnecessary complexity to avoid very few users

With the Renderer migration, this is officially unnecessary, and
should always be true for supported encrypted content.

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.

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.
