The Disconnect a refusing session sent carried the ack of the very frame it
refused, so the sender saw the frame acknowledged. The session forgets its
peer's sequences before building the goodbye, and a server-mode transport
forgets its endpoint so only a Connect can claim it again.
CultNetRudpSession::answer_repeated_connect is the one answer to a repeated
Connect for the hub and the document server: it records the sequence (the
document server's old accept_connect did, and a client that reconnects in one
session depends on it), applies acks, queues nothing, and returns the pending
Accept or an Ack.
