44ba1565d9 segment: Replaced gst_segment_to_position with gst_segment_position_from_running_time
gst_segment_to_position might cause confusion, especially with the addition of
gst_segment_position_from_stream_time . Deprecated gst_segment_to_position
now, and replaced it with gst_segment_position_from_running_time.

Also added unit tests.

c0d4b1b646 segment: Added gst_segment_position_from_stream_time()
gst_segment_position_from_stream_time() will convert stream time into a
position in the segment so that gst_segment_to_stream_time() with that
position returns the same stream time. It will return -1 if the stream time
given is not inside the segment.

60130eb5f0 segment: Rewording of struct field descriptions

bc282da83c segment: remove the bounds check from _to_running_time_full()
Do not do any checks for the start/stop in the new
gst_segment_to_running_time_full() method, we can let this be done by
the more capable gst_segment_clip() method. This allows us to remove the
enum of results and only return the sign of the calculated running-time.
We need to put the old clipping checks in the old
gst_segment_to_running_time() still because they work slightly
differently than the _clip methods.

See https://bugzilla.gnome.org/show_bug.cgi?id=740575

edf484ab6b segment: add option to disable clipping
Add a clip argument to gst_segment_to_running_time_full() to disable
the checks against the segment boundaries. This makes it possible to
generate an extrapolated running-time for timestamps outside of the
segment.

Add GST_SEEK_FLAG_TRICKMODE_KEY_UNITS and
GST_SEEK_FLAG_TRICKMODE_NO_AUDIO, and rename GST_SEEK_FLAG_SKIP
to GST_SEEK_FLAG_TRICKMODE (with backwards compat define).

cc41130664 segment: mark GstSegmentFlags as flags rather than enum
... which really makes a difference when trying to serialize
a flags value which is a combination of flags, which is hard

c8840b8270 segment: add offset field
Add an offset field that is used to track at what position the segment was
updated. This is used to set the running time to 0 when we do a flushing
seek that doesn't update the position.

49ea16e041 segment: make sure we don't have unmapped seek flags littering out segment flags
Make GstSeekFlag to GstSegmentFlag conversion explicit, and
set only those seek flags in the segment flags which are
mapped. This makes sure we don't have extraneous flags
littering our segment flag field, which also fixes the
debug printing/serialisation of segment events in the
debug log.

bdbc069348 Rework GstSegment handling
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.
