  Log:
  Oops, pc98 is independent of i386 for clock.c and machdep.c but not
  for clock.h, so changing th i386 clock.h broke it.  MFi386 (not tested):
  
  Cleaned up declaration and initialization of clock_lock.  It is only
  used by clock code, so don't export it to the world for machdep.c to
  initialize.  There is a minor problem initializing it before it is
  used, since although clock initialization is split up so that parts
  of it can be done early, the first part was never done early enough
  to actually work.  Split it up a bit more and do the first part as
  late as possible to document the necessary order.  The functions that
  implement the split are still bogusly exported.
  
  Cleaned up initialization of the i8254 clock hardware using the new
  split.  Actually initialize it early enough, and don't work around it
  not being initialized in DELAY() when DELAY() is called early for
  initialization of some console drivers.
  
  This unfortunately moves a little more code before the early debugger
  breakpoint so that it is harder to debug.  The ordering of console and
  related initialization is delicate because we want to do as little as
  possible before the breakpoint, but must initialize a console.
