handler.

GST_STATE. Ugggggg.

last return value from a state change to the app.
Update some debug statements with proper category.

fix for a nasty little missed situation where an installed plug-in

for the uninstalled one (not in the registry) didn't get its
->registered set to TRUE
Original commit message from CVS:
2005-10-31 Andy Wingo <wingo@pobox.com>
* Boo!
* gst/gstqueue.c (gst_queue_chain): Fix downstream leaky mode.
* gst/gstobject.c (gst_object_dispatch_properties_changed): No
need to serialize property notifications on GLib 2.8. GLib 2.6 has
the possibility of deadlocks here if code calling notify() or
set() has a lock that can be taken in another notify handler (ABBA
with class lock and e.g. python GIL state lock).
Original commit message from CVS:

Original commit message from CVS:
* gst/elements/gstfilesink.c: (gst_file_sink_do_seek),
(gst_file_sink_get_current_offset):
Use fseeko() and ftello() if available. When falling back on
lseek() to get the current offset, fflush() first to make sure
everything is up-to-date and we get the right offset.
Original commit message from CVS:
* gst/base/gstbasesink.c: (gst_base_sink_commit_state),
(gst_base_sink_get_position), (gst_base_sink_query),
(gst_base_sink_change_state):
Simply set the right flag when going to playing, that's all
we need to do instead of calling a function inside the object
lock (that could take the lock as well and deadlock)
Original commit message from CVS:
* gst/base/gstbasesrc.c: (gst_base_src_do_seek),
(gst_base_src_loop):
Don't warn, the peer element knows what to do best when
the seek failed, it might try something else.

Reworked the message handling a bit, cache the messages instead of
only the senders. alows us to do more in the future.
Original commit message from CVS:
* docs/design/part-TODO.txt:
Update TODO
* gst/base/gstbasesink.c: (gst_base_sink_get_position),

(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):

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/gstmessage.h:
* tools/gst-launch.c: (event_loop):
Seriously, this is better than a previous commit as we only need
to notify the fact that an element changed state in a streaming
thread, marking the state of the parents dirty, hence the
STATE_DIRTY message instead of abusing a boolean in a STATE_CHANGE
message.
Original commit message from CVS:
* gst/gstbin.h:
* gst/gstelement.c: (gst_element_class_init),
(gst_element_set_state), (gst_element_set_state_func):
* gst/gstelement.h:
Pending ABI changes.
GThreadPool in GstBinClass to monitor async state changes.
state_cookie in GstElement to detect concurrent gst/set state.
set_state is now virtual too in case a very complicated element
has to be constructed.

Make messages future proof.
state-change gets a flag if it was a message comming from the
streaming thread.
segment-start/stop can also be specified in other formats.
A message to notify an app that a pipeline changed playback
