The prototype is built upon Transformer and took many references from
TransformerAudioRenderer.
Please take a look and we can discuss more details.

The result is plumbed back to `MediaCodecRenderer` via a new
`DrmSession#requiresSecureDecoder` method.
This allows us to use the `MediaDrm#requiresSecureDecoder` method added
in Android 12:
https://developer.android.com/reference/android/media/MediaDrm#requiresSecureDecoder(java.lang.String)
This change also removes
`FrameworkMediaCrypto#forceAllowInsecureDecoderComponents`, replacing it
with equivalent logic in `FrameworkMediaDrm#requiresSecureDecoder`.

Adding a CHANGE_FRAME_RATE_STRATEGY_ALWAYS strategy is
omitted from this commit, since adding it is more complicated
than just plumbing it through and leaving everything else
unchanged. Specifically, VideoFrameReleaseTimeHelper would
need updating to behave differently when such a strategy is
enabled. It currently calls setFrameRate in cases such as
pausing, seeking and re-buffering, on the assumption that
changes to the underlying display refresh rate will only be
made if they can be done seamlessly. For a mode in which
this will not be the case, it makes more sense to stick to
the content frame-rate when these events occur. It may also
make sense to only use explicit content frame-rate values,
and not those inferred from individual frame timestamps.
Finally, for adaptive content containing a mix of frame-rates,
it makes sense to use the maximal frame-rate across all
variants, and to avoid calling setFrameRate on switches from
one variant to another.
Applications that know the frame-rate of their content can
set ExoPlayer's strategy to CHANGE_FRAME_RATE_STRATEGY_OFF and
then use setFrameRate directly on the output surface. Note that
this is likely to be a better option for apps than anything we
could implement in ExoPlayer, because the application layer
most likely knows the frame-rate of the content earlier than
ExoPlayer does (e.g., to perform the disruptive mode switch
at the same time as an activity transition).
Adding CHANGE_FRAME_RATE_STRATEGY_ALWAYS will be deferred
until there's clear demand for it. In the meantime, we'll
recommend the alternative approach above.

This CL moves SubtitleDecoder and all its dependencies
to common in order to enable using it in extractor
module while implementing SubtitleExtractor.

This change removes ERROR_CODE_IO_NETWORK_UNAVAILABLE,
ERROR_CODE_IO_NETWORK_CONNECTION_CLOSED, and ERROR_CODE_IO_DNS_FAILED
in favor of keeping only ERROR_CODE_IO_NETWORK_CONNECTION_FAILED.

The AnalyticsCollector releases listeners lazily so that listener
callbacks triggered on the application looper after
SimpleExoPlayer.release() are still handled. The change in ListenerSet
to post the onEvents callback on the front of the application looper
changed (correctly) how onEvents are propagated, however this made
the AnalyticsCollector deliver onEvents with out-of-order EventTimes.
This change fixes AnalyticsCollector to trigger onPlayerReleased() and
the matching onEvents() event in the correct order.

This change aligns all the names for classes that are 'holders of static
methods' to be `ApiNN`. Classes that hold state are named meaningfully
based on that state.

This CL addresses the github issue [#8946](https://github.com/google/ExoPlayer/issues/8964). That issue requests support for `font-size` CSS property in WebVTT subtitle format. This CL:
* Adds support for `font-size` property by extending capabilities of WebVTT `CssParser`. Implementation of `font-size` property value parsing is based on the one in `TtmlDecoder`.
* Adds unit test along with test file containing WebVTT subtitles with all currently supported `font-size` units.

The dokka javadoc generation tool complains when parameter names don't match between a method and its override. This change updates occurrences where there is currently a mismatch.

The dokka javadoc generation tool complains when parameter names don't match between a method and its override. This change updates occurrences where there is currently a mismatch.
Notable renamings that might be controversial:
- `onPlaybackStateChanged(int state)` to `onPlaybackStateChanged(int playbackState)` affected a lot of lines but seems more consistent with other '-Changed' methods.
- `handleMessage(int messageType, Object payload)` to `handleMessage(int messageType, Object message)`
- `ExtractorInput` and `DataSource` inherit `DataReader` which had `read(byte[] target, ...`, while data sources normally called the first parameter `buffer`. I have standardized these all to use `buffer` even though it looks out of place in the `ExtractorInput` interface (which has more `read` methods with `target`).

The reason this was not an IO error code is that before other
IOExceptions were classified, this catch would grab non-IO error
codes, like ParserException. Now that we are getting closer to
the final state, we can assume IOExceptions are ok to classify
as IO error codes (unlike, for example, ParserExceptions or
DrmSessionExceptions).
