Benno Rice cae2c81dc2 Mega-patch for OpenFirmware loader support.
- Flesh out ofw_readin routine.
- Add OpenFirmware load and exec routines.
- Make sure memory allocation for the kernel is done correctly.
- Change the way the heap is allocated so as to make it easier to deallocate
  when we hand over.
- Add a command to print memory maps similar to the one for ia64.

With this patch, I can now load and hand over to a kernel on my iMac.  There
are some problems with OpenFirmware routines failing after the hand over that
still need to be addressed.
