When the bin does an upward state change, try to avoid doing a downward state
change on the child and vice versa.
Add some more unit tests for this fix.
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=621833
Currently fails (in normal circumstances) because we create a
socket pair for each bin's bus and exhaust the number of available
file descriptors.
https://bugzilla.gnome.org/show_bug.cgi?id=646624
When an error message is received on the bus, mark the bin as being in the error
state and unlock all current _get_state() calls with an error.
Fixes#505770
When an element is removed from a bin because it caused a state change error,
don't unref the child twice.
Add some more debug info.
Add a unit test for this error.
Fixes#615756
Post a stream-status message indicating that a new task was created so that the
application has a chance to change the properties of the task.
Fix unit test to take into account the new ref of the message.

* gst/gstbin.c: (gst_bin_add_func), (gst_bin_remove_func),
(gst_bin_change_state_func), (bin_handle_async_done),
(gst_bin_handle_message_func):
Fix race for bins that simulate ASYNC state changes by inserting
ASYNC_START and ASYNC_DONE messages in their bus. We need to check for
pending ASYNC messages even when the bin does not have ASYNC children.
We note detect this behaviour because we will receive an ASYNC message
that is originating from the bin itself.
Fixes races with decodebin2 state changes.
* tests/check/gst/gstbin.c: (GST_START_TEST):
Add some more debug.
Original commit message from CVS:
* gst/gstbin.c: (add_to_queue), (remove_from_queue), (clear_queue),

Fix annoying bug in the sorted iterator where a sink that is not really
a sink (when it has downstream links) screwed up the iterator.
* tests/check/gst/gstbin.c: (GST_START_TEST), (gst_bin_suite):
Unit test to verify the fix.
Original commit message from CVS:
* tests/check/gst/gstbin.c: (GST_START_TEST):

with it.

Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.

Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.
Post ASYNC_START and ASYNC_DONE messages.
Change lost_state so that we go to PAUSED and wait for the parent to set
us to PLAYING again (so latency calculation can be performed)
Export gst_element_change_state() method so that subclasses can use it.

Using the new ASYNC_START message we can reset the base_time when
needed. This can then be used to implement base_time redistribution in
flushing seeks so that we can remove the explicit seek handling.
Perform latency query and configuration when going to PLAYING.

Fix test because the bin will not set the async element to PLAYING right
away.
* tests/check/gst/gstbin.c: (pop_async_done), (GST_START_TEST):
Make the message check a little stronger.
Handle ASYNC messages.
* tests/check/pipelines/cleanup.c: (GST_START_TEST):

Expect ASYNC_DONE messages.
Original commit message from CVS:
* tests/check/gst/gstbin.c: (GST_START_TEST):
It is acceptable to have a refcount of 2 or 3 at this point in the
test, because the pipeline might be just posting its state_change
message. The next line then waits for that message to appear using
bus_poll, so that should be fine too.

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.

Fix test case: we can't rely on a fixed state change order when
going from READY => PAUSED because the sink might commit its
new state first when the first buffer created by the source
reaches the sink before the source has finished its change state.
(Test case still fails at times, see #316856, comment 5 onwards)

Fix state change order when there is only a semi sink (#316856)
