We misinterpretted the EXT-X-START tag before. Now, we ignore this tag and parse segment times from the segments themselves. This is more robust for both VOD and live HLS content. We avoid segment parsing when updating normal, well-behaved live streams. For poorly-behaved live streams, we will fall back to segment parsing and recover. This also addresses the issue of VOD content which does not start at zero. Instead of using configuration to make this playable, we will now offset VOD content back to 0 automatically. Issue #740 Closes #1011 Change-Id: Ib3a59f87e3a050244cd39854409d8e3542c50b0a
