Follow-up Comment #13:

I'd be glad to get a better working version of the "accepts_pending"
implementation. The current way of letting the user application keeping track
of the corresponding listen pcb is really bad.

I'd favour an implementation where the stack decreases "accepts_pending"
before calling the "accept" callback and the application has to call API
functions (on the connection pcb) to increase/decrease "accepts_pending" (or a
2nd counter) when connections are put on a queue.

One possible improvement would be to remove the "accept" callback from
non-listening pcbs and giving them a pointer to their listen-pcb instead
(which has the accept callback pointer). Closing a listen-pcb would require
walking all pcb lists, but that could be worth it.
