  Log:
  SVN rev 199189 on 2009-11-11 15:43:07Z by jh
  
  Create verifier used by FreeBSD NFS client is suboptimal because the
  first part of a verifier is set to the first IP address from
  V_in_ifaddrhead list. This address is typically the loopback address
  making the first part of the verifier practically non-unique. The second
  part of the verifier is initialized to zero making its initial value
  non-unique too.
  
  This commit changes the strategy for create verifier initialization:
  just initialize it to a random value. Also move verifier handling into
  its own function and use a mutex to protect the variable.
  
  This change is a candidate for porting to sys/nfsclient.
