master playlist variable definitions at the moment of parsing.

When playing a playlist where the exact maximum input size is known from the
container for each item, it may be necessary to recreate the decoder to increase
its maximum input buffer size at the point of transitioning from one item to the
next, which can make transitions non-seamless.

Scale up the initial video decoder maximum input size so playlist item
transitions with small increases in maximum sample size don't require
reinitialization.

Apps targeting API 28 by default do not grant permission for cleartext traffic,
so update the demo app to show a warning if loading an HTTP URI will fail. See

information on behavior changes in API 28.

Future changes for checking codec capabilities will go in the renderer rather
than in the codec selector, so the codec selector only needs a MIME type as
before.

Add automatic audio focus handling to SimpleExoPlayer. Audio focus
handling is an opt-in feature that can be requested by passing
the system's AudioManager and an AudioFocusConfiguration to
SimpleExoPlayer.setAudioFocusConfiguration.

When audio focus is being managed by SimpleExoPlayer, the player
will transparently handle pausing playback during
AUDIOFOCUS_LOSS_TRANSIENT, as well as lowering playback volume
during AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK.
