Don't use the duration in the segment for calculating clipping values.
The duration is expressed in stream time and clipping is done on unrelated
timestamp values.
This used to be interesting for elements that used the segment structure to
implement seeking because then they would use stream-time for the segment
start/stop values and the duration could be used as a fallback when the stop
position was not set. Now that the complete segment event is passed between
elements we cannot do this anymore because some elements might store the
duration and start/stop values with different time bases in the segment.
Improve GstSegment, rename some fields. The idea is to have the GstSegment
structure represent the timing structure of the buffers as they are generated by
the source or demuxer element.
gst_segment_set_seek() -> gst_segment_do_seek()
Rename the NEWSEGMENT event to SEGMENT.
Make parsing of the SEGMENT event into a GstSegment structure.
Pass a GstSegment structure when making a new SEGMENT event. This allows us to
pass the timing info directly to the next element. No accumulation is needed in
the receiving element, all the info is inside the element.
Remove gst_segment_set_newsegment(): This function as used to accumulate
segments received from upstream, which is now not needed anymore because the
segment event contains the complete timing information.
Before it returned that [start,stop] is inside the segment and that the
difference between segment_start and start needs to be clipped. If the
clipping is done on a buffer (like in baseaudiosink) this will result
in the data pointer being at a invalid memory position.
Fixes bug #589849.
Add gst_segment_to_position() that converts a running_time to a position in the
segment. A faulty variant of this function is currently used in inputselector
but we'll need it for frame stepping too.

Original commit message from CVS:
* gst/gstsegment.c: (gst_segment_set_newsegment_full):
Set the last_stop to a more meaningful position when configuring the
segment. ie. the start/stop of the segment or clipped against the
updated segment boundaries.
* tests/check/gst/gstsegment.c: (GST_START_TEST):
Add some unit tests for the last_stop.
Original commit message from CVS:

* tests/check/gst/gstsegment.c:
No, let's not use g_slice_{dup|copy} here, since they only exist
since GLib 2.14 and we still depend only on >= 2.12. Also add
unit test for gst_segment_copy().
Original commit message from CVS:
* gst/gstsegment.c:
The glib macro seems to be borked. Use g_slice_copy directly and cast
in the hope that this fixes the warning on 64bit.
