Log:
  MFC r305679: Switch random_get_pseudo_bytes() shim to arc4rand().
  
  Our shim for Solaris random_get_bytes() uses read_random(), that looks
  reasonable, since it guaranties reliably seeded random data.  On the other
  side Solaris random_get_pseudo_bytes() does not provide this guarantie,
  and its original Solaris implementation is equivalent to our arc4rand(),
  using software crypto without stressing slower hardware RNG.
