  Log:
  MFC rtsock.c:1.129:
    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.
