send_event() of parent class (i.e., GstBinClass) iterates srcpads
to send SEEK event. And performing it per srcpad is inefficient.
So, let's drop duplicated SEEK event by checking seqnum

To satisfy follwing restriction of HLS spec 6.3.3,
select startup fragment sequence to 4th from end of playlist.
Also, seek range should exclude last three fragment in playlist.
"the client SHOULD NOT choose a segment which starts less than
three target durations from the end of the Playlist file."
https://bugzilla.gnome.org/show_bug.cgi?id=777682
hls live starts playback from the allowed latest fragment,
but its "sequence position" is set to zero, and so stream
time is also set to zero.
This does not make sense, because hls live allows seeking to past position,
and it's negative stream time from downstream element's point of view.
Note that, allowed seekable range (and seeking query) is
from the first fragment of playlist to the allowed latest fragment.

HLS spec 6.3.3 is saying that
"the client SHOULD NOT choose a segment which starts less than
three target durations from the end of the Playlist file."
To ensure above statement, the third fragment from the end of playlist
should be excluded from seekable range and also from available starting fragment.
(i.e., the fourth fragment from end of playlist is the starting fragment).
https://bugzilla.gnome.org/show_bug.cgi?id=777682
During live playback, the first fragment in a updated
playlist can be advanced from that of startup playlist.
Meanwhile, since hlsdemux finds target seek position
by just accumulating fragment's duration, the base should
be adjusted to the updated first fragment's timestamp.

In some places a GST_FLOW_FLUSHING result was return as a FALSE
gboolean and then returned from a parent function as
GST_FLOW_ERROR. This prevented seeking from working.

Without failing, we would play back random parts of the stream which is
arguably a worse user experience, and failing is also recommended by the
spec here.
And also handle live streams without any media sequence numbers at all
properly, that is, make sure the sequence numbers are increasing instead
of starting again at 0 every time.

Parsing SIDX box was allowed even if "indexRange" attribute does not appear
for On-Demand profile. However, actual seeking using SIDX index did not happen
since download loop keep working on.
To use SIDX index in that case, demux should try it in the next download loop.
