Windows: rx lowlevel nat ping

Browse Source 
sha1 d24078658d added support
for a low-level nat ping using rx version replies.

Export rx_SetConnSecondsUntilNatPing from afsrpc.dll.

Add NatPingInterval registry value to
  HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon\Parameters
to permit Nat Ping to be enabled.  The default value is 0 seconds.
