(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_base_transform_get_size), (gst_base_transform_buffer_alloc),
(gst_base_transform_event), (gst_base_transform_handle_buffer),
(gst_base_transform_set_passthrough),
(gst_base_transform_is_passthrough):
* 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),
(gst_event_new), (gst_event_new_custom), (gst_event_get_structure),
(gst_event_new_flush_start), (gst_event_new_flush_stop),

(gst_event_parse_qos), (gst_event_new_seek),
(gst_event_parse_seek), (gst_event_new_navigation):
* gst/gstevent.h:
Make GstEvent use GstStructure. Add parsing code, make sure the
API is sufficiently generic.
Mark possible directions of events and serialization.

* gst/gstmessage.c: (gst_message_init), (gst_message_finalize),
(_gst_message_copy), (gst_message_new_segment_start),

(gst_pad_set_caps), (gst_pad_send_event):
Update for new events.
Catch events sent in wrong directions.

Event updates.

* gst/gsttag.c:
* gst/gsttag.h:
Remove event code from this file.

* libs/gst/dataprotocol/dataprotocol.c: (gst_dp_packet_from_event),
(gst_dp_event_from_packet):
Event updates.
