The GlEffectsFrameProcessor that will be part of the effects module
uses the DebugViewProvider. So it does not make sense for it
to be an inner interface of Transformer.

After this change GlEffects can use any GlTextureProcessor not just
SingleFrameGlTextureProcessor.
MediaPipeProcessor now implements GlTextureProcessor directly which
allows it to reuse MediaPipe's output texture for its output texture
and avoids an extra copy shader step.

After this change, FrameProcessorChain chains any GlTextureProcessors
instead of only SingleFrameGlTextureProcessors.
The GlTextureProcessors are chained in a bidirectional manner using
ChainingGlTextureProcessorListener to feed input and output related
events forward and release events backwards.

This is useful for testing Transformer in the same way as it is used
in tests and to see only the real transformation time.

Based on
https://developer.android.com/reference/android/media/MediaCodec#using-an-output-surface,
frame dropping behaviour depends on the target SDK version.
After this change transformer will only use
MediaFormat#KEY_ALLOW_FRAME_DROP if both the target and system SDK
version are at least 29 and default to its pre 29 behaviour where each
decoder output frame must be processed before a new one is rendered
to prevent frame dropping otherwise.
Also remove deprecated Transformer.Builder constructor without a
context and the context setter.

Transformer always enabled glAssertionsEnabled, so there should
be no functional change.
ExoPlayer previously disabled glAssertionsEnabled, so GlUtil logged
GlExceptions instead of throwing them. The GlExceptions are now
caught and logged by the callers so that there should also be no
functional change overall.
This change also replaces EGLSurfaceTexture#GlException with
GlUtil#GlException.

SingleFrameGlTextureProcessor is now an abstract class containing a
default implementation of the more flexible GlTextureProcessor interface
while still exposing the same simple abstract methods for single frame
processing it previously did.
FrameProcessorChain and GlEffect will be changed to use
GlTextureProcessor in follow-ups.

Once the more advanced GlTextureProcessor interface exists,
it will be possible to change the output size of a GlTextureProcessor
between frames. To keep the re-configuration based on the frame sizes
minimal, things indepedent of the frame size, such as the GlProgram,
can be initialized in the constructor.

These legacy callbacks are currently forwarded to onSetMediaUri which
will be removed in the future.
Also make sure to only call player.prepare/play after the items have
been set.
The calls to onAddQueueItem are also forwarded to onAddMediaItems to
actually allow a session to resolve these items to playable media, which
wasn't possible so far.

(cherry picked from commit 208a9114a9f516f7034b75b4f21f9ded34de8501)
The MediaItemFiller is not flexible enough for most realworld usages
because:
- it doesn't allow asynchronous resolution of MediaItems (e.g. to
look up URIs from a database)
- it doesn't allow to batch updates for multiple items or do more
advanced customizations (e.g. expanding a mediaId representing
a playlist to multiple items).
Both issues can be solved by passing in a list of items and
returning a ListenableFuture. The callback itself can also move
into MediaSession.Callback for consistency with the other
callbacks.

Decode-only video frames (needed when the frame at / first frame after the
clipping start is not a key frame) need to be decoded but not passed to
the frame processor chain or encoder.
The clipping start offset needs to be removed from the frame timestamps
in the passthrough and video pipelines.
There are no changes needed for this in the audio pipeline, as it doesn't
use the input timestamps -- it uses its own timestamps derived from the
buffer sizes instead.
Also add demo option to try this out.

Also update names of implementations to match design doc.
In follow-ups, SingleFrameGlTextureProcessor will become
an abstract implementation of a new GlTextureProcessor
interface.
Texture processor makes sense as it processes OpenGL textures.
The term frame processor will be used for something else in
follow-ups.

* Rename (via deprecation)
`MediaItem.DrmConfiguration.Builder#forceSessionsForAudioAndVideoTracks`
to `setForceSessionsForAudioAndVideoTracks`. This is more consistent
with existing 'force' method names both in this class and in
`TrackSelectionParameters.Builder`.
* Add missing `@Nullable` annotation to the parameter for
`MediaItem.SubtitleConfiguration.Builder#setMimeType`. This annotation
is already present on the `MediaItem.SubtitleConfiguration#mimeType`
field that this setter corresponds to.

Put cloud storage samples at the top to avoid having a sample at the top of the list where we don't control the server.
Also update labels not to mention progressive container type, as it's irrelevant for Transformer, which always transmuxes even if it doesn't transcode.

This listener replaces
FrameProcessorChain#getAndRethrowBackgroundExceptions.
The listener uses a new exception type FrameProcessingException
separate from TransformationException as the frame processing
components will be made reusable outside of transformer soon.

This constant is used for https://docs.gl/es2/glVertexAttribPointer
which takes the number of components per generic vertex attribute
(meaning the size of the individual coordinate vectors here) not the
number of attributes (the number of vertices that the old constant
name referred to).

This change splits AdvancedFrameProcessor into 4 files:
- MatrixTransformationFrameProcessor for the GlFrameProcessor
implementation
- MatrixTransformation and GlMatrixTransformation for the GlEffect
specification
- MatrixUtils for the static matrix helpers

This fixes some small niggles:
1. `inferContentType(String)` is documented to take a path, but in the
tests we're passing full URIs.
2. A `String` parameter is usually a path, but also a MIME type or an
extension. In the new methods, the meaning of a `String` parameter
is always clear from the name of the method.
3. `inferContentType(String)` is always passed an extension in
'production' code (which has to be manually prefixed with a dot).
4. `inferContentType(Uri, @Nullable String)` always ignores the Uri if
the String is non-null. IMO this logic is clearer to a reader if it's
just in-lined at the call-site.
These methods are used from the demo apps, so will be part of the stable
API.
