Joey Parrish b0238c3c00 Stop using segment position in HLS parser ...

As part of Period-flattening, I'm trying to reduce our dependence on
the "position" field of SegmentReference.  If it can be eliminated, we
can more easily concatenate Arrays of SegmentReferences without
modifying them.

The HLS parser uses positions to find previously-resolved segment
times when refreshing a live playlist.  What we're really doing is
using HLS media sequence numbers, since we use those to assign the
segment positions in the first place.

This change makes the use of media sequence numbers more explicit, and
adds a per-Stream map from media sequence number to segment start
time.

The only other users of segment positions are StreamingEngine and
various tests.

Issue #1339 (period-flattening)
