MFC r261786, r261789

  Rework the EARLY_PRINTF mechanism.  Instead of defining a special eprintf()
  routine, now a platform can provide a pointer to an early_putc() routine
  which is used instead of cn_putc().  Control can be handed off from early
  printf support to standard console support by NULLing out the pointer
  during standard console init.

  Convert two while(1); statements into proper panics.
