stream: improve async handling

Browse source 
We can remove most of the special async handling in adapter, filter and
stream because this is now handled in the core.

Add a node.data-loop property to assign the node to a named data-loop.

Assign the non-rt stream and filter to the main loop. This means that
the node fd will be added to the main-loop and will be woken up directly
without having to wake up the RT thread and invoke the process callback
in the main-loop first. Because non-RT implies async, we can do all of
this like we do our rt processing because the output will only be used
in the next cycle.
