(gst_type_find_handle_src_query), (find_element_get_length),
(gst_type_find_element_activate):
API change fix.

* gst/gstquery.c: (gst_query_new_position),
(gst_query_set_position), (gst_query_parse_position),
(gst_query_new_duration), (gst_query_set_duration),
(gst_query_parse_duration), (gst_query_set_segment),
(gst_query_parse_segment):
* gst/gstquery.h:
Bundling query position/duration is not a good idea since duration
does not change much and we don't want to recalculate it for every
position query, so they are separated again..
Base value in segment query is not needed.

* gst/gstqueue.c: (gst_queue_handle_src_query):
* gst/gstutils.c: (gst_element_query_position),
(gst_element_query_duration), (gst_pad_query_position),
(gst_pad_query_duration):
* gst/gstutils.h:
Updates for query API change.
Added some docs here and there.

1cef8c5b5a check/: Small state change torture test.
Original commit message from CVS:
* check/Makefile.am:
* check/pipelines/stress.c: (GST_START_TEST),
(simple_launch_lines_suite), (main):
Small state change torture test.

* docs/design/part-states.txt:
* gst/base/gstbasesink.c: (gst_base_sink_commit_state),
(gst_base_sink_handle_object), (gst_base_sink_event), (do_playing),
(gst_base_sink_change_state):
Never take state lock from streaming thread, clean up ugly
hacks. Unfortunatly core does not yet support nice ways to
async commit state.

* gst/gstbin.c: (gst_bin_remove_func), (gst_bin_recalc_state),
(bin_bus_handler):
Start state recalc if a STATE_DIRTY message is posted, but only
on the toplevel bin.

* gst/gstelement.c: (gst_element_sync_state_with_parent),
(gst_element_get_state_func), (gst_element_abort_state),
(gst_element_commit_state), (gst_element_lost_state),
(gst_element_set_state_func), (gst_element_change_state):
* gst/gstelement.h:
State variables are now protected with the LOCK, the state
lock is only used to serialize _set_state().
