  Log:
  Bootstrap updates.
  
   - Move some startup code from MD to MI sections
   - Add a 'copyout' and some copyout-related functions.  These will be
     obsoleted when BTX is available for the 386 and the kernel load
     area becomes directly addressable.
   - Add the ability load an arbitrary file as a module, associating
     and arbitrary type string with it.  This can be used eg. for loading
     splash-screen images etc.
   - Add KLD module dependancy infrastructure.  We know how to look for
     dependancies inside KLD modules, how to resolve these dependancies
     and what to do if things go wrong.  Only works for a.out at the
     moment, due to lack of an MI ELF loader.  Attach KLD module information
     to loaded modules as metadata, but don't pass it to the kernel (it
     can find it itself).
   - Load a.out KLD modules on a page boundary.  Only pad the a.out BSS
     for the kernel, as it may want to throw symbols away.  (We might want
     to do this for KLD modules too.)
   - Allow commands to be hidden from the '?' display, to avoid cluttering
     it with things like 'echo'.  Add 'echo'.
   - Bring the 'prompt' command into line with the parser syntax.
   - Fix the verbose 'ls'; it was using an uninitialised stack variable.
   - Add a '-v' flag to 'lsmod' to have it display module metadata as well
     (not terribly useful for the average user)
   - Support a 'module searchpath' for required modules.
   - The bootstrap file on i386 is now called 'loader' to permit the
     /boot directory to use that name.
   - Discard the old i386 pread() function, as it's replaced by
     arch_readin()
