Original commit message from CVS:
* CHANGES-0.9:
* docs/design/part-TODO.txt:
* docs/design/part-events.txt:
Some docs updates

* gst/base/gstbasesink.c: (gst_base_sink_handle_object),
(gst_base_sink_event), (gst_base_sink_do_sync),
(gst_base_sink_activate_push), (gst_base_sink_activate_pull):
* gst/base/gstbasesrc.c: (gst_base_src_send_discont),
(gst_base_src_do_seek), (gst_base_src_event_handler),
(gst_base_src_loop):
* gst/base/gstbasetransform.c: (gst_base_transform_transform_caps),
(gst_base_transform_configure_caps), (gst_base_transform_setcaps),

* gst/elements/gstfakesink.c: (gst_fake_sink_event):
* gst/elements/gstfilesink.c: (gst_file_sink_event):
Event updates.

* gst/gstbuffer.h:
Use faster casts.

* gst/gstelement.c: (gst_element_seek):
* gst/gstelement.h:
Update gst_element_seek.

* gst/gstevent.c: (gst_event_finalize), (_gst_event_copy),

API is sufficiently generic.
Mark possible directions of events and serialization.
