Currently we prefer technical preferences set in the Parameters over
content preferences implied by the media. It proably makes more
sense in the opposite order to avoid the situation where a
non-default track (e.g. commentary) is selected just because it
better matches some technical criteria.
Also add comments explaining the track selection logic stages.

This is already called in GlUtil.Program().
Tested by confirming that the demo-gl target still runs as expected.
Refactoring change only. No intended functional changes.

And also tweak existing role flag logic to strictly prefer perfect
matches over partial matches.
Caveat: Video role flags only supported for fixed track selections
(same issue as Issue: google/ExoPlayer#9519).

This allows to check if the media metrics service is available outside
the actual constructor and to fail gracefully if it is missing.

- This format is passed to the PassthroughPipeline, which doesn't use
any decoder.
- In most other cases where it is used, it is not relevant that this
format will be or has been passed to the decoder. What's relevant is
that it is the format of the input.

We need the filename of the output videos to be predictable, because
MobileHarness requires the exact filename to pull the file.

Fixes the gradle compilation failures.
Gradle dependencies need revising if we want to be using this, as
checkerframework is ahead of their latest version, such that we
can't compile.

This change moves methods that are the same in
`TransformerAudioRenderer` and `TransformerVideoRenderer` to
`TransformerBaseRenderer`.

This inheritance is really confusing because ExoPlayerImpl is not
a full Player interface implementation. It also claims to be an
ExoPlayer implementation in the Javadoc which isn't true in its
current state.
Removing the inheritance also allows to clean up some unused methods.

This is documented on the setter already, but it seems to make sense to do this in the constructor as well for clarity.

Before this change ExpPlayerImplInternal dropped a change of the playing period when a change in the timeline occurred that actually changed the playing period but we don't want to update the period queue. This logic also dropped the update of a skipped server side inserted preroll ad for which we want the periodQueue to 'seek' to the stream position after the preroll ad and trigger a SKIP discontinuity.
This change now introduces an exception so that a skipped SSI ad is still causing an update in the period queue which leads to a 'seek' and a discontinuity of type SKIP.

Document that apps should retain `GlUtil.Program` while the program is in use,
and keep a reference to attributes/uniforms within the program to make sure
they don't get GC'd causing any allocated buffers passed to GL to become
invalid.
Tested manually by running gldemo and transformer.

The features supported by `TranscodingTransformer` are a
superset of those supported by `Transformer` after merging
the video renderers in
35c891a7bf.
This change removes `TranscodingTransformer` and adds its features to
`Transformer`.

Buffers that are useful to pass to the sample/passthrough pipeline
should either contain data or the end of input flag. Otherwise, passing
these buffers along is unnecessary and may even cause the decoder to
allocate a new input buffer which is wasteful.

The player will not play ads in final states (played, skipped, error)
again. To allow ads loader customizations to play ads again, we can
add a method that resets the state back to available or unavailable
(depending on whether we have the URI for the ad).

Currently, DrmSessionManager takes player specific values (= the
playback looper) through (pre)acquireSession calls and requires
the caller to pass in the same values every time.
Instead, we can configure the DrmSessionManager for playback with
a player once before it's being used. We can't simply extend the
prepare() method as prepare may be called before the player is
created to prewarm the DrmSessionManager.
The new method also takes a PlayerId which is bound to the lifetime
of the player similar to the playback looper.
To avoid breakage of custom MediaSources with DRM, we can keep the
old the SampleQueue.createWithDrm method as deprecated.

The `SefSlowMotionVideoSampleTransformer` drops frames by
setting `buffer.data = null` and updates the timestamps of the
frames it keeps. However, these buffers with dropped frames
are still used in the pipeline as they may contain other useful
information, specifically whether the end of the input has been
reached. So, the timestamps should also be updated for the buffers
where frames are dropped.

In the near future, we will be able to specify which tests run on this
target explicitly, at which point this ignore will be removed.

The local tracks variable was used to assign the initial subtext
for the current track selection in the menu, but the new value
was only assigned after the subtext has been evaluated.
Assign the local variable first, so that the remaining accesses
the latest value.

The `GlUtil` wrappers for attributes/uniforms allocate buffers that are passed into OpenGL, and it seems that the distorted output was caused by these buffers being garbage collected.
The issue was difficult to reproduce manually. Add a test that does repeated transcodes in a loop (marked `@Ignore` for now because it runs for a long time and requires network access so may be flaky) to make it easier to run many transcodes and look for inconsistent output. For now the consistency check is just based on the file size which is very likely to change if the actual video frames change.
Verified that the test fails before, and passes once the attributes and uniforms are stored in fields as in this CL.

This change merges `TransformerMuxingVideoRenderer` and
`TransformerTranscodingVideoRenderer` into `TransformerVideoRenderer`.
Besides all features supported by `TransformerTranscodingVideoRenderer`
the new merged `TransformerVideoRenderer` also supports SEF slow motion
flatting without re-encoding like the `TransformerMuxingVideoRenderer`.
To do this, it uses a `SefSlowMotionVideoSampleTransformer` with
the `PassthroughPipeline`.

This mime type is technically for the Muxer, and determines
the container used. In the context of the transformer, this can
be thought of more as a container mime type, to avoid confusion
with the video mime type and audio mime type.
Deprecates setOutputMimeType().

Before, the `MAX_SEQUENCE_NUMBER` is 65535, such that the logic to get the next
sequence number:
`previousSeqNumber + 1 % MAX_SEQUENCE_NUMBER`
yields 0 when `previousSeqNumber` is 65534. However, the next sequence number
should be 65535.
