stream_filter/httplive.c: split up parse_SegmentationInformation() function.

Split up parse_SegmentInformation() into two functions:
parse_SegmentInformation() - parse #EXTINF to get duration
  parse_AddSegment() - adds new segment

The parse_SegmentInformation() did both functions before and this
made some HTTP Live URL not work as expected. The splitting up of
these functionalities solves this issue.
