  Log:
  CPU localize dummynet(4) step 2/2:
  - Add ip_dn_sockopt() in net/dummynet/ip_dummynet_glue.c, which
    o  Copy socket option from user space.
    o  Dispatch get/config/delete/flush operation to CPU ip_dn_cpu, so we don't
       even need to enter critical section when iterating pipes/flow_sets or
       checking whether dummynet has loaded.
    o  Copy out information from kernel space to user space.
  - Adjust raw_ip.c to call ip_dn_sockopt() instead of checking DUMMYNET_LOADED
    and calling ip_dn_ctl_ptr.
  - Remove now unnecessary critical section protection, however, replying dn_msg,
    setting and clearing ip_dn_io_ptr still need to be protected by critical
    section, since dn_msg and ip_dn_io_ptr are touched/checked by systimer
    callback.
