An active boolean is introduced on producer side: it reflects whether
the source is active (at interrupt controller level or at VFIO level
- automasked -).
This is a temporary hack for ARM IRQ forwarding with vfio platform.
I think the connect and disconnect should become callbacks too.
This would make possible to handle error in the process. Typically
active could be returned by producer->stop and analyzed before going
further. in that case the list_add only if connect returns 0.
