  Log:
  Parallelize ifnet.if_addrhead accessing by duplicating the list itself
  on each CPU, each list element points to ifaddr:
  - Add SI_SUB_PRE_DRIVERS before SI_SUB_DRIVERS, so action could be taken
    before drivers' initialization (mainly before NIC driver's if_attach())
  - Move netisr_init() to the FIRST of SI_SUB_PRE_DRIVERS, so that
    netmsg_service_port_init() could be called in earlier stage of system
    initialization.
  - Create one thread on each CPU to propagate changes to ifnet.if_addrhead.
    Their thread ports are registered with netmsg_service_port_init() for
    port syncing operation.
  - Change to ifnet.if_addrhead begins in netisr0, i.e. serial of changes
    to ifnet.if_addrhead are serialized by netisr0
  - ifaddr's refcnt is moved to its list elements, i.e. per-CPU refcnt.
    They are initialized to 1 instead of 0.
  - A magic field is added to ifaddr list element to make sure that IFAREF
    and IFAFREE are called on valid ifaddr list element.  This field is
    initialized to a magic value and is wiped out once the list element's
    refcnt drops to 0
  - To close the gap between testing and freeing, once the ifaddr list
    element's refcnt drops to 0, ifa_portfn(0) (a thread's port on CPU0) is
    poked to check whether ifaddr is referenced on other CPUs, if not, then
    ifaddr is freed on ifa_portfn(0)
