necessary symbols needed per subsystem. Main kvm(3) init is now delayed as much as possbile. This finally fixes performance issues reported in kern/167204. Some non-working code (ng_socket.ko symbol addresses calculation) removed. Some global variables eliminated. PR: kern/167204 MFC after: 4 weeks
