[PATCH] Fix a race condition accessing the decode_chain field.
Make sure that any access to the GstDecodeBin's decode_chain field is protected using the EXPOSE_LOCK. Also add a simple reference counter to the GstDecodeChain structure so that when the type_found signal fires it can hold onto the decode chain even while the EXPOSE_LOCK is not held. This should fix a race condition if the type_found signal fires right in the middle of a state change that messes with the same decode chain. https://bugzilla.gnome.org/show_bug.cgi?id=755260
