Log:
  Set default uid/gid to nobody/nogroup for NFSv4 mapping.
  
  The default uid/gid for NFSv4 are set by the nfsuserd(8) daemon.
  However, they were 0 until the nfsuserd(8) was run. Since it is
  possible to use NFSv4 without running the nfsuserd(8) daemon, set them
  to nobody/nogroup initially.
  Without this patch, the values would be set by the nfsuserd(8) daemon
  and left changed even if the nfsuserd(8) daemon was killed. Also, the default
  values of 0 meant that setting a group to "wheel" would fail even when
  done by root and this patch fixes this issue.
