* gst/gstelement.c (gst_element_get_compatible_pad_template): Fix
the debugging on whether the caps are compatible.

* testsuite/threads/threadi.c: (cb_data), (cb_play), (main):
On Wim's request, split the test in three separately-compiled
tests that each test a very specific bug. Two of them still fail,
will create bugs for those. threadi.c indicates why they fail.
Original commit message from CVS:
* gst/schedulers/gstoptimalscheduler.c:

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),

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.
