Prototype fix for IPsec authentication related functions

  Some of IPsec authentication related functions should have
  'const' for its 2nd argument, but not now.
  But if someone try to use them, and passed const data for
  those functions, then much bogus compile warnings will be
  generated.
  So those funcs prototype should be modified.
