These references will be re-written to PlayerView when exporting to
exoplayer2, so this commit results in some small reformatting changes.

Using chunkless preparation greatly improves start up time if the master
playlist declares CODECS for the renditions. Hence, we turn this on
by default as it benefits most well-defined HLS master playlists.
The only known reason why developers may want to turn this feature off is
when the renditions contain muxed closed-caption tracks that are not
declared in the master playlist. So this change also updates the documentation
and RELEASENOTES to point out this caveat.
