gst/gst.defs: Update API definitions.

Browse source 
Original commit message from CVS:
* gst/gst.defs:
Update API definitions.
* gst/common.h:
* gst/gstpad.override:
Add wrapper functions for settings activate, activatepull and
activatepush functions on pads.
* gst/gst.override:
Wrapper for gst_segment_set_seek() and gst_segment_clip()
Remove global ignore for *_init(), allows gst_segment_init() to be
properly code-generated.
* testsuite/Makefile.am:
* testsuite/test_segment.py:
Add unit test for gst.Segment object.
