Port "client_port: Make all data members private" from yuzu (#4064)
* client_port: Make all data members private These members don't need to be entirely exposed, we can instead expose an API to operate on them without directly needing to mutate them We can also guard against overflow/API misuse this way as well, given active_sessions is an unsigned value. * make the condition an assert
