Extend the loader so that GRUB can accept a loader which comes
back to GRUB when a loaded image exits. Also, this change adds
support for a chainloader on EFI.
* term/efi/console.c: Include grub/misc.h.
(grub_console_checkkey): Display a scan code on the top for
debugging. This will be removed once the EFI port gets stable.
Correct the scan code mapping.

allocate memory from larger regions, in order to reduce the number
of allocated regions. Otherwise, the MacOSX loader panics.

possible, to avoid allocating a region near to 1MB, for the MacOSX
loader.

prototype.

handle.

initialization can use modules. Also, this change adds an
intensive debugging feature for the memory manager via the

PART.LEN.
