> The pn_dispatcher_t class has two intertwined purposes -
> * To hold some temporary and scratch data used for processing incoming and outgoing frames.
> * To dispatch incoming frames to frame handling code.
> It turns out that the first purpose is overhead: The temporary data can be better passed
as parameters to the code that is using it; The scratch data is duplicated and would be better
put in the associated pn_transport_t which is where is ends up going anyway.
> The second purpose turns out to boil down to 1 boolean and some code which can be handled
differently. The boolean is to tell the dispatcher to stop.
