HLS Live comes in two flavors: LIVE and EVENT. EVENTs append segments to the end of the playlist, but do not ever remove segments. LIVE can both append segments to the end and remove segments from the beginning of the playlist. This CL lays the ground for supporting both types and introduces support for EVENTs. Issue #740.
