docs/pwg/advanced-types.xml: Fix description for buffer-frames=0.
Original commit message from CVS:
* docs/pwg/advanced-types.xml:
Fix description for buffer-frames=0.

* gst/gstbin.c: (gst_bin_child_state_change_func),
(gst_bin_change_state), (gst_bin_change_state_norecurse):
* gst/gstbin.h:
* testsuite/threads/Makefile.am:
* testsuite/threads/threadi.c: (cb_timeout), (cb_quit), (cb_eos),
(cb_state), (cb_play), (main):
Fix non-recursive state changes to *really* change the state
of the object, and not just call parent_class->state_change.
Fix a lot of lockups caused by this. Fixes #132775. Add test
for the problem. Also enable test to show #142588 (fixed).
* gst/gstthread.c: (gst_thread_change_state),
(gst_thread_child_state_change):
Don't exit the thread if we go to NULL and are inside thread
context. Instead, return control to the main thread context
and exit from there.
* gst/gstelement.c: (gst_element_disable_threadsafe_properties):
Don't unset virtual functions, since those may still be used.
That's not necessarily correct, but suffices for now.

(cb_error), (main):
Add tests to show #150546. Pass, but should fail (currently
disabled from the testsuite).
* gst/gstscheduler.c: (gst_scheduler_dispose):
Dereference child schedulers on dispose (#94464).
* testsuite/bytestream/filepadsink.c: (gst_fp_sink_init):
Fix typo.
* testsuite/threads/thread.c: (main):

(bin_handle_async_done), (gst_bin_handle_message_func):
* gst/gstbin.h:
Immediatly commit the toplevel bin state when receiving an async-done
message. This enables us to avoid spawning a thread to commit the state
in some common cases and it also avoids some races.
Avoid spawning a state thread when adding/removing async elements to a
toplevel bin. Instead we immediatly update the bin state.
Get rid of iterating all the children when getting the state in the bin
because it is now always up-to-date.
Fix bug where locked elements would always return _SUCCESS even it they
returned NO_PREROLL before being locked.
Fix the order of the state_change, async-start/done messages that was
sometimes incorrect.
Mark the state_dirty field as deprecated, we don't need it anymore as we
are always up-to-date.
* gst/gstelement.c: (gst_element_get_state_func),
(gst_element_continue_state):
Small debug inprovements.
Return the previous element state return when nothing is pending instead
of blindly returning SUCCESS.
* tests/check/generic/sinks.c: (GST_START_TEST), (pad_blocked_cb),
(gst_sinks_suite):
Add a whole bunch of new testcases.
