KongQun Yang b85e5c9368 Use segment duration in buffer depth calculation
Segment start,end time was used previously, which could result in
problems if there are discontinuity in the streams. E.g. if the
stream has timestamp, 10000, 10001, 10002 and then next segment
comes in with timestamp 1. With the previous logic, all the segments
would remain in the time shift buffer until after 10000 segments
even with a small time shift buffer depth of 10.

This could also happen when timestamp wraps around, which could
happen during long time of live streaming.

This change will also be useful to support multi-period live DASH.

Fixes #563.

KongQun Yang cf40accaa8 [HLS] Fixing AdCues handling in iframe playlists
Previously for the last iframe in a segment, we wait for the next
segment to arrive before writing the EXTINF tag. If an Ad Cue comes
in before the next segment, the EXT-X-PLACEMENT_OPPORTUNITY tag would
be inserted before the iframe in previous segment.

Fixes #378, #396.

Two-character ISO-639 code in --default_language was ignored due to
a bug in language code matching as the language code in stream is

KongQun Yang b3194866a6 [HLS] Add CHANNELS attribute to #EXT-X-MEDIA
As specified in HLS spec (https://tools.ietf.org/html/rfc8216):

All audio EXT-X-MEDIA tags SHOULD have a CHANNELS attribute.  If a
Master Playlist contains two Renditions encoded with the same
codec but a different number of channels, then the CHANNELS
attribute is REQUIRED; otherwise, it is OPTIONAL.
