Test application to demonstrate the bug

I wrote a small video looping test and found that looping with non-segment seek
no longer work with oggdemux. The
bug was tracked down to GstSegement::base being set as NONE in
gst_segment_do_seek() if position is outside the segement. After discussion
with Wim, it's a normal that position is slightly outside the segment since
being equal or outside is what most demuxer checks to determin EOS. Instead of
clamping the value in every demuxer, we suggested doing the clamp in the
gst_segment_do_seek() helper function. Path coming.
