- Media Playlist that is non-VERSION 1 must have EXT-X-VERSION.
- Attribute for EXTINF should be CODECS instead of CODEC.

- Removed unnecessary check if MediaInfo has media_info_name, in
  SimpleHlsNotifier::NotifyNewStream().

Jacob Trimble a80e16bab0 Close files in Finalize for WebM segmenters.
Now Finalize() will close all the files used by the segmenters.  This
is important to allow WebMMuxer::FireOnMediaEndEvent to get the
correct size of the media file.

This also changes the WebM muxer to use 64-bit numbers for the init
and index ranges to correctly support >4GB files.
