Buffers would always start with timestamp 0 and we'd start streaming from the first buffer, but live streams always start streaming from the last fragment - 3 fragments in the playlist, which makes its timestamp, as returned by get_next_fragment, be whatever position they had in the playlist. This makes sure the position correctly reports the position of the buffer in the playlist, and added a shifting variable to allow seeking in the middle of fragments.
