These changes are in part related to handling playback of mixed clear
and encrypted content, where we might want to use a secure decoder
throughout, but only have drm init data and only care about the state
of the DrmSession during playback of encrypted parts.

- requiresSecureDecoderComponent became unnecessary when we added
  ExoMediaCrypto, which provides a layer in which requiresSecureDecoderComponent
  can be overridden.
- Relaxed requirements for obtaining the MediaCrypto. It's helpful
  to allow retrieval in the error state, since it can be used to
  instantiate a decoder and play clear samples.
- Deferred throwing of errors in renderer implementations. As long as
  we can get a MediaCrypto, we should init the codec. We can also
  play clear samples without failing if playClearSamplesWithoutKeys is
  true, regardless of the errors state.

The media source allows adding or removing child sources before and after prepare() was called.

This is currently happening after toggling the repeat mode. This is line with
the rest of the implementation which requires a seek operation to resume
playback.

prepared. Added this to JavaDoc of these method to simplify implementations.

- Restore making the playback controls visible on any key press.
- Turn anti-aliasing on for drawing the scrubber circle. It looks
  really ugly on some devices if you don't do this.

Add a compatibility AudioAttributes class so that the app can specify
audio attributes in the same way before and after API 21.

Deprecate SimpleExoPlayer.setStreamType. Add
SimpleExoPlayer.setAudioAttributes and MSG_SET_AUDIO_ATTRIBUTES.

This prevents ExoPlayer from thinking there are many more video tracks
than there actually are. And will prevent downloading multiple times
the same rendition once offline support for HLS is added.

With this change, it becomes possible to depend on ExoPlayer
locally in settings.gradle by doing:

gradle.ext.exoplayerRoot = 'path/to/exoplayer/root'
apply from: new File(gradle.ext.exoplayerRoot, 'core_settings.gradle')

You can optionally add a prefix onto ExoPlayer's module names
by adding:

gradle.ext.exoplayerModulePrefix = 'prefix'

It's currently difficult to use ExoPlayer modules in other gradle
projects because they rely on constants and dependencies defined
in our own top level gradle file. This change moves the constants
into a separate file referenced directly from each module. It also
removes the need for the top level gradle file to declare a
dependency on com.novoda:bintray-release. This is now only needed
if "exoplayerPublishEnabled = true" is specified.

This will allow MediaSources to provide MediaPeriods that correspond to ad
breaks in a timeline period rather than content for a timeline period, in a
future change.

Getting active status of caching is needed to display on UI. Instead of a listener interface polling was chosen because of simplicity and better suits to UI refreshing.

CachingCounters.downloadedBytes was updated after whole data is downloaded. Now it's updated for each read into buffer. Buffer length defines how finer these updates are.

CachingCounters.totalBytes is added so UI can display a progress bar.

This change allows you to enable/disable tracks within which
all samples are key-frames without any re-buffering (e.g. audio,
text and metadata). This effectively reverts V2 back to the
behavior in V1, only this time we're doing it properly. []ly
disabling/enabling, or disabling/enabling whilst paused, no longer
cause samples to get "lost" between the source and renderers.

Note it also becomes really easy to support a few other things,
although support is not exposed in this change:

- Enable/disable video tracks without any re-buffering, by
  changing the toKeyframe argument passed to discardTo to true.
- Retain media in the buffer for some time after it's been played
  (e.g. to support a single back-5s-seek efficiently), by
  subtracting the desired back-buffer time from the value that's
  passed to discardTo.
