fixed crashy race condition when querying master servers. 

try to do something about crazy cursor biases in games that are not likely to get the QSG cursor.
fix unvised q3bsp pvs. again.
add cl_delay_packets cvar as a clientside analogue to sv_minping (which is often unchangeable by the actual players).
fix a qcc issue with static locals screwing everything up.
fix dpmaster issues when NQPROT isn't defined.
