This required modifying the __sip_ack function to return a boolean instead of returning void.

While making this change, I noticed that the "ignore" parameter in handle_response could never be TRUE and that it wasn't even used anyway, so I removed it. This change also made the lastnoninvite field on a sip_pvt useless, so I removed it as well.
