This allows the same DefaultMediaSourceFactory instance to be used as
the contentMediaSourceFactory inside
ImaServerSideAdInsertionMediaSource.

This makes SimpleExoPlayer a simple forwarding wrapper which can be
removed in the future.
The changes are all purely mechanical with none of the potential further
simplifications made yet. The only exceptions are name clashes where
either EPI or SEP was calling a method in one of the classes and both
classes had different implementations for the same method name. In these
cases we needed to disambiguate between the two different
implementations (example: ExoPlayerImpl.setListener was renamed to
setEventListener).

The current implementation of ExoPlayer Cea708 is processing the whole service block without
taking into account the defined service block size, which could cause the execution of
unwanted command.
The following set of Cea708 represents a real use case of the above.

The above frames should be displaying the following text on the screen (or at least the first part of it).

ExoPlayer is currently parsing this block as follow (in parentheses the defined service block size):

which is what we are looking for.
This PR modifies service block parsing logic to honor service block size instead of read the full service block buffer.

Tested by confirming transformations still work and write to a output file in a
scoped-storage directory on a:
* Nexus 6P API 23 emulator
* Google Pixel 4 API 31 physical device

In some cases we create empty playback metrics with no corresponding
events (e.g. when an app seeks to a new media item and immediately
releases the player). There is no benefit in having completely empty
metrics entries, so it's cleaner to not report them in such cases.

- Add a checkbox in the demo app to enable experimental HDR editing.
- Add an `experimental_` method to `TransformationRequest` to enable HDR editing.
- Add fragment/vertex shaders for the experimental HDR pipeline. The main difference compared to the existing shaders is that we sample from the decoder in YUV rather than RGB (because the YUV -> RGB conversion in the graphics driver is not precisely defined, so we need to do this to get consistent results), which requires the use of ES 3, and then do a crude YUV -> RGB conversion in the shader (ignoring the input color primaries for now).
- When HDR editing is enabled, we force using `FrameEditor` (no passthrough) to avoid the need to select another edit operation, and use the new shaders. The `EGLContext` and `EGLSurface` also need to be set up differently for this path.

TransformerTest sounds like a unit test for Transformer but these
tests test behaviour that involves multiple stages of the pipeline.

Some phone with limited memory can't allocate bigger
shared memory buffers.
This might or might not be related to Binder's 1M
transaction limit.

1h.

This makes sure the number of ads in an ad group matches to the number of periods representing an ad group in a multi-period timeline. This makes it easier to accurately mark ads as played in multi-period windows which is needed to correctly prevent seeking over unplayed ads.

If
a) the end of stream buffer arrives with a frame rather than an
empty buffer or
b) processDataV29() renders several decoder output buffers to the
FrameEditor's input Surface immediately before encountering the
EOS flag
these frames were previously stuck in the FrameEditor's input Surface
and never fed to the encoder.

This test tests that all frames are processed when transcoding
video to a different sample MIME type (and that the transformation
completes successfully).
