Log:
  Adjust initialization of random(9) so it is usable earlier.

  A few existing SYSINITs expect the in-kernel PRNG (random(9)) to be
  useable at SI_SUB_RANDOM / SI_ORDER_ANY.  However, the random(4) overhaul
  merged for 10.0 performs all of its initialization at SI_SUB_DRIVERS
  (since it is tied in with creating the /dev/random character device).

  This has changed in HEAD where the random initialization is split such
  that the in-kernel random(9) is initialized at SI_SUB_RANDOM and the
  supporting bits for userland random(4) (such as /dev/random) are initialized
  later.

  However, the changes in HEAD are large and invasive.  Instead, this change
  is being directly committed to stable/10.

  This change moves most of the random(9)/random(4) initialization to
  SI_SUB_RANDOM with the exception that the creation of the harvesting kernel
  process and the /dev/random character device are deferred to new
  SYSINITs that run at SI_SUB_DRIVERS.

  This fixes the "random device not loaded; using insecure entropy" message
  output during boot on some systems.
