Original commit message from CVS: Another big set of changes. Connections are now also pullfunc based. gstqueue has been updated, I don't know of any other connections offhand. There are still a few things that need doing, specifically the concept of a source or connection with connections to multiple thread contexts is not dealt with. This may force us to move the threadstate from the element to the pad, maybe keeping the element's copy for simple cases. Then the Bin would create a structure to pass to the cothreaded _wrappers of any such elements, which would detail the pads that are to be dealt with by this particular cothread context. That will speed things up to, since we don't have to look through the list of all pads for every Src or Connection element for every iteration, we can simply step through the list provided by the plan. Special case might even have a single pad pointer sitting there to trump the list, if there's only one (the common case anyway). Task 23098 is tracking these changes. The main task 22588 depends on that subtask, as well as 22240, which is a consistency check on PAD_DISABLED.
