MP4 edit lists sometimes ask to start playback between two samples.
If this happens, we currently change the timestamp of the first
sample to zero to trim it (e.g. to display the first frame for a
slightly shorter period of time). However, we can't do this to audio
samples are they have an inherent duration and trimming them this
way is not possible.

Add a fail-fast check in `ExoPlayerImpl` to ensure the equality of the lengths of `ShuffleOrder` and the current playlist. Also improve the documentation of `setShuffleOrder(ShuffleOrder)` with explicit instruction on this.

It currently wrongly documents that it is only called before reading
streams (that has never been the case and all MediaPeriods already need
to handle calls after reading samples from the streams).
It was also a bit unclear what a discontinuity implies and the new
Javadoc calls out the main use case for discontinuties and the intended
meaning of returning a discontinuity.

*** Original commit ***
Mark output sample as decode-only based on start time
We currently do the same check on the input timestamps and
expect the output timestamps to match. Some codecs produce
samples with modified timestamps and the logic is a lot safer
when the comparison with the start time is done on the output
side of the codec.

FallbackListener.onTransformationRequestFinalized() is called from the
AssetLoader thread for audio, and from the GL thread for video.

By passing this class where it's needed, implementations don't need to store it
in a field (reducing boilerplate) and it's clearer that it can't be unset when
needed.

`MediaControllerImplBase` has 2 methods for updating listeners about `PlayerInfo` changes - `updatePlayerInfo` (for masking the state) and `onPlayerInfoChanged` (when communicating with the session). There is a set number of listener callbacks related to `PlayerInfo` updates and both methods should go through the same control flow (whether we know that masking will ignore most of them or not).
A unified method `notifyPlayerInfoListenersWithReasons` encapsulates only the shared logic of 2 methods - listeners' callbacks. This ensures that both methods call them in the same order and none are missed out.

With the upcoming "handle format changes" CL, stereo -> mono audio
would add an AudioProcessor. Robolectric decodes output encoded data,
which crashes some AudioProcessors because the number of frames may not
be an integer.

This change uses this new method everywhere we currently `instanceof`
check an `Extractor` directly. This allows us to introduce
wrapping/delegating `Extractor` instances - because the `instanceof`
checks will continue to operate on the underlying instance.
HLS is a slightly different case, because it directly re-instantiates
`Extractor` instances, which is not compatible with an arbitrary
wrapping structure. Luckily the only `Extractor` instances that HLS
re-instantiates do not support muxed subtitles, so won't be wrapped
in the first place (although future changes might use the
delegating-`Extractor` pattern for other purposes, which might affect
HLS).

The callbacks for `PlayerInfo` changes are currently in both `MediaControllerImplBase.updatePlayerInfo` (masking) and `MediaControllerImplBase.onPlayerInfoChanged`. But the order was different between them both and `ExoPlayerImpl.updatePlaybackInfo` which they are trying to mimic.

The effects pipeline must receive images in the sRGB colorspace due to the color transfers applied in the shaders. Currently the burden to making sure images are in the right colorspaces falls onto apps. This CL ensures that this is not the case anymore.

When an app tried to re-prepare a live streeam with server side inserted
ad after a playback exception, the player tried to find the ad group by
its index in the ad playback state of the next timeline when creating
the first period.
If a source that supports server side ad, has removed the ad playback
state when the source has been removed, this causes a crash. For live
streams this is a reasonable thing to do given the exception could be
caused by an invalid ad playback state.
This change removes the ad metadata from the current period for live
streams and the timeline. In case the ad playback state is not reset
by the source, the first timeline refresh would ad the metadata again.
