Original commit message from CVS:
2004-11-27  Martin Soto  <martinsoto@users.sourceforge.net>

* gst/gst.override (_wrap_gst_event_new_any)
(_wrap_gst_event_new_discontinuous)
(_wrap_gst_event_any_get_structure)
(_wrap_gst_registry_pool_plugin_list):
* gst/gst.defs (get_data, event_new_any, any_get_structure):
Added basic support for "ANY" (navigation) events.
Added basic support for discont events (only one value for now,
we are limited by the GStreamer API).
Now it is possible to access data in a GstBuffer as a string
Added a definition for method get_data of GstBuffer.

* gst/gst.override (_wrap_gst_structure_set_value): Add an
optional parameter to allow selection of the right G_TYPE. If no
type is specified, make an educated guess.
