FIXES 4811

"in rx_packet.c:rxi_ReceiveDebugPacket() the rx_idleServerQueue is
scanned without taking a lock first.

The queue_Remove macro zeroes the ->next field (luckily), but this can
lead to a crash when Murphy strikes and the entry gets removed during
the scan: queue_Scan will dereference 0x0 -> next.
