  Modified files:
    sys/net              rtsock.c 
  Protect interface and address lists using the appropriate mutex. These
  locks were not aquired because the user buffers were not wired, thus it was
  possible that that SYSCTL_OUT could sleep, causing a number of different
  problems such as lock ordering issues and dead locks.
  -Wire user supplied buffer to ensure SYSCTL_OUT will not sleep.
  -Pickup ifnet locks to protect the list.
  -Where applicable pickup address locks.
  -Pickup radix node head locks.
  -Remove splnet stubs
  -Remove various comments about locking here, because they are no
   longer needed.
  It is the hope that these changes will make sysctl_rtsock MP safe.
