Increased performance doing pull_range in blocks of 32Kb instead of 4Kb.
Caching the value of gst_adapter_available instead of calling it 3 times.
Added some comments with the header descriptions.
Peek enough data to avoid a corner case where could be readed data outside
the buffer.
Speed up some more inlining some functions and keeping another stream pointer
list to be used as iterator.
Sprinkle branch prediction macros accross the code.
Handling the seeking with flush in pull mode in the proper way.
Ensure that the clossing segment is generated correctly and being
properly pushed.
Added some GST_DEBUG to check it.
Ensure that last_stop is updated in stream time.
Calculate duration as delta of PTS as it seems more correct than delta
of SCR in some clips that I tested.
Original commit message from CVS:
* gst/mpegdemux/gstmpegdemux.c: (gst_flups_demux_send_data):

The position member in the newsegment event corresponds to the
stream_time of the segment start position.
