Pausing emulation requires to access the CPU thread, which might be blocked
waiting for inputs by netplay. Accessing it in this state would cause the
whole GUI to hang for set timeout (10s).
Instead of sleeping in NetPlayClient::GetNetPads and NetPlayClient::WiimoteUpdate,
now use std::condition_variable. This allows for finer control over these blocking
areas.
