2c822735ba hlsdemux2: Add HLS playlist loader

streams.

52d577eee1 adaptivedemux2: Fix for failed download handling
When playing at the live edge of a live playlist, and a download fails, we don't
expect there to be a next fragment. That case is handled lower down anyway, so
don't retry infinitely on spurious http errors at the live edge.

9848c1a1a1 m3u8demux2: Fix off-by-one and leak.
Fix an off-by-one in gst_hls_media_playlist_sync_to_playlist() that would ignore
the first fragment in the reference playlist.  The error was harmless, since we
expect the reference playlist to be older than the playlist we're
synchronising (so the first/oldest segment in the reference playlist will likely
not exist in the new playlist), so this is just for correctness.

Also fix a segment leak in gst_hls_media_playlist_advance_fragment() when
ignoring the partial_only segment.

d76aacfb82 hlsdemux2: LL-HLS improvements
Fixes for stream_time recalculation and handling in partial segments.

Disallow bitrate switching when in the middle of partial segments - only at a
full segment (or right before the first partial segment of a segment).

It's possible but more difficult to switch bitrates in the middle of a partial
segment group, since they are less likely to have aligned keyframes. In any
case, the seek code can't do that right now.

023c67e166 hlsdemux: Consider starting stream time in presentation offset
When calculating the presentation offset for CMAF input in live
playback, subtract the stream_time of the fragment from the
calculated presentation offset, so that the first fragment
is played at running time zero.

The stream selection is done on the currently outputting tracks, but in order to
(de)activate the backing streams we can only do it if the input and output
period are identical.

When matching segments across playlists with Program-Date-Times,
use the difference in segment PDTs to adjust the stream time
that's being transferred. This can fix cases where the
segment boundaries don't align across different streams
and the first download gets thrown away once the PTS
is seen and found not to match.

33db765f45 adaptivedemux2: Improve minimum buffering threshold
Previously the minimum buffering threshold was hardcoded to a specific
value (10s). This is suboptimal this an actual value will depend on the actual
stream being played.

This commit sets the low watermark threshold in time to 0, which is an automatic
mode. Subclasses can provide a stream `recommended_buffering_threshold` when
update_stream_info() is called.

Currently implemented for HLS, where we recommended 1.5 average segment
duration. This will result in buffering being at 100% when the 2nd segment has
been downloaded (minus a bit already being consumed downstream)
