that require more encryption data, like the encryption pattern.

This is most commonly caused by malformed media, where
the media indicates that something we need to make an
allocation for is *really huge*. Failing playback is
appropriate for this case; killing the process is not.

Added repeat mode toggle buttons to UI. Current mode gets forwarded to
Exoplayer instance, but without playback behaviour changes yet.
Translations for button descriptions are also missing - this will be another CL.

The default byte order for ByteBuffers is big endian, but platform decoder
output buffers use native byte order. AudioProcessors handle native byte order
input/output.

When using a software audio decoding extension the Sonic audio processor would
receive big endian input but was outputting to a native byte order buffer,
which could be little endian. This mismatch caused audio output to be
distorted.

After this change both platform decoder and extension decoder output buffers
should be in native byte order.

If the codec isn't adaptive, there's no need to accommodate
the width/height/input-size of streams that don't have the
same resolution as the current stream. This is because we'll
always need to instantiate a new codec anyway.

A DummySurface is useful with MediaCodec on API levels 23+.
Rather than having to release a MediaCodec instance when the
app no longer has a real surface to output to, it's possible
to retain the MediaCodec, using MediaCodec.setOutputSurface
to target a DummySurface instance instead. When the app has
a real surface to output to again, it can call swap this
surface back in instantaneously. Without DummySurface a new
MediaCodec has to be instantiated at this point, and decoding
can only start from a key-frame in the media.

A future change may hook this up internally in MediaCodecRenderer
for supported use cases, although this looks a little awkward. If
this approach isn't viable, we can require applications wanting
this to set a DummySurface themselves. This isn't easy to do with
the way SimpleExoPlayerView.setPlayer works at the moment, however,
so some changes will be needed either way.

Looper.myLooper(), the default looper, may be null in background threads. This adds a fallback to use the main app looper.

This will allow ExoPlayer instances to be built in background threads in Photos.

When using the CronetEngine.Builder class, it automatically selects the
Cronet version preferring higher version codes and falling back to a Java
Http implementation if no native or GMSCore version is available.

This version selection has now been moved into the CronetEngineFactory
class to always prefer GMSCore over natively bundled versions. We also
ignore the Cronet internal Java implementation. Instead, users of
CronetDataSourceFactory can provide their own fallback factory. If none is
provided, we use DefaultHttpDataSourceFactory.

Using the new getNextWindowIndex method of Timeline, LoopingMediaSource now
uses a InfinitelyLoopingTimeline which does not unroll the windows to
157 million iterations but just starts from the beginning. If an explicit
number of iterations is given, we still unroll.

This change also allows multi-window timebars to show infinitely looping
playlists correctly.

The blaze BUILD file for the Cronet extension now has three options:
Using native bundled Cronet libs, using GMSCore, or using whichever is newer.
The GMSCore version is preselected (as it is the smallest), but other variants
may be used by uncommenting the respective lines.

The API is the same for all cases and the CronetEngine.Builder automatically
selects the newest option or falls back to default http.

To avoid that apps using this extension need to add a dependency to Cronet
themselves, I added a CronetEngineFactory to the Exoplayer extension.

Gradle builds can't be supported (as far as I can see), as the GMSCore Cronet
version is first party only.

(Preparation for Repeat Toggle Function - GitHub Issue #2577)

In addition, Timeline now also got a getPreviousWindowIndex and a
getNextPeriodIndex method with default implementations.

Changed ExoPlayerImplInternal and PlaybackControlView to use these
methods at all occurances of period and window index operations.

Note: Does not include repeat mode yet and no timelines are actually
using it so far. Please wait for the next CLs for this.

To inject custom renderers into SimpleExoPlayer, developers
currently need to extend SimpleExoPlayer and override the
renderer building methods. This is in contrast to the rest
of the library, where we use proper injection. This change
restores consistency. I think it's fine to make
SimpleExoPlayer final again, but if we find people extending
it for non-renderer purposes, we can revert that part of the
change.

ExoPlayerFactory now has analogous methods for the simple
and non-simple cases, which is a nice outcome.

When using a multi window time bar, the onScrubStop method uses another
method to estimate the seek position than the updateProgress method for
rendering the time bar. If the time line contains windows starting with an
ad period followed by other content, they differ in their behaviour.
 - updateProgress checks all periods and leaves out all ad periods
 - onScrubStop only checks windows and leaves them out when the first
   period is an ad.

Changed onScrubStop to fit approach in updateProgess.

Partially fixes Github Issue #2661

Fixes the following issues:

1. When a surface is set, it's expected that the renderer will
notify video size + when a frame is rendered to it. This is true
even if the surface isn't changing. Right now this is achieved
by setting renderedFirstFrame to false, but this is problematic
in the case that the surface isn't changing because (a) it will
force rendering of a subsequent frame to the output even when
paused, which is incorrect, and (b) isReady will return false
until this occurs.

2. When the surface really is changing, isReady can return false
until the first frame has been rendered into the new surface, which
will break seamless surface switching. This change allows isReady
to return true up to allowedJoiningTimeMs for this case.

* colorSpace, colorRange and colorTransfer are relevant to all videos.
* The rest of the fields are relevant only to HDR videos.
* Tested on a prototype device that decodes VP9 profile 2, 10 bit.
* The Webm spec spells color as 'colour' so the webm id reference use the same spelling.
