Instead of having types in flac inherit types in vorbis, make types in
vorbis inherit types in flac. This is a bit of a hack and somewhat
messy, but it retains backwards compatibility.
Collapse the two variations of `VorbisUtil.buildMetadata` into a single
method called `VorbisUtil.parseVorbisComments` that only takes a list
of vorbis strings, compared to previously where it would take strings
and picture frame instance. Any code that relied on the old signature
now either concatenates picture frames and vorbis comments or copies
vorbis comments into an existing metadata instance.
Simplify how the comment header is parsed and eliminate a few possible
bugs in the process, such as:
- Metadata being overwritten directly by the comments header.
- The packet being rewound to 0 if it cannot find a comment header,
which might result in the cursor being moved to a bad position.
Studio accidentally renamed some of the javadoc to reflect the new
vorbis module. Revert it to the dev javadoc, as the ExoPlayer devs
don't update the javadoc until a release.
In the old `flac` module, superclass the deprecated types under the
moved types in the `vorbis` module. This ensures backwards compat
with existing library users.
Adaptive video and audio selections will be limited to formats with
the same level of DecoderSupport and HardwareAccelatationSupport, unless
specifically allowed by new flags.
If different levels of decoder support are available, prefer primary
over fallback decoders and hardware-accelerated over software decoders
(in this order). For video, also prefer more efficient codecs, if both
are supported by hardware-accelerated primary decoders.

This change moves the video track selection to the generic
selection method introcuced for audio and text. This ensures
we can apply the same criteria for fixed and adaptive video
track selections. Implicitly, this reorders the preferences
for adaptive tracks to give non-quality preferences (like
preferred MIME type or preferred role flags) a higher priority
than number of tracks in the selection.

This does currently only happen by chance in replaceStream (called from
enable) if the stream previosly played read until C.TIME_END_OF_SOURCE.
enable already makes all changes done in resetPosition (except resetting
the reading position), so it's less error-prone and makes the intention
clearer if the same code is called from both enable and resetPosition.
The effect of this bug was quite limited because the numerical value
of readingPositionUs was only relevant for periods with changing
durations and server-side inserted ads.

The app will be notified about fallback using a callback on
Transformer.Listener. Fallback may be applied separately for
the audio and video options, so an intermediate internal
FallbackListener is needed to accumulate and merge the track-specific
changes to the TransformationRequest.

We currently run (almost) the same code for all track types.
De-duplicate this by using a single method that takes functional
interfaces for track-type dependent logic.
This has the benefit that all track-type dependent logic is
contained within their subclasses and the generic logic doesn't
need to make any assumption about the eligibility of tracks for
selection or adaptation, and doesn't need to access Parameters.
Make this change for audio and text only for now. Video can
be updated in a subsequent change.

Simplifying and clarifying variables, and adding comments.
Tested by confirming demo-gl and demo-transformer both
correctly display videos

This value is the default used by widevine_test at
proxy.uat.widevine.com, but it's not easy to find that info so it's
clearer to document it explicitly here for consistency with the "policy
tests" section below where all the URLs contain a video_id parameter.

The existing wording would be correct if prefixed with
"Returns false if [...]", but it seems confusing to a document a boolean
method in terms the condition it returns false - so I reworded it in
terms of when it returns true.

After this change exceptions throw by MediaCodec during
encoding/decoding will result in TransformationExceptions with
ERROR_CODE_ENCODING_FAILED/ERROR_CODE_DECODING_FAILED.
Before this change ERROR_CODE_FAILED_RUNTIME_CHECK was used.
