i386: use ACPI to power off the machine

This is a mostly verbatim copy of acpihalt.c from GRUB2 with a little
bit of glue code.

* i386/grub/mm.h: Likewise.
* i386/grub/symbol.h: Likewise.
* i386/grub/time.h: Likewise.
* i386/grub/types.h: Likewise.
* i386/i386at/acpi.c: Likewise.
* i386/i386at/acpihalt.c: Likewise.
(grub_acpi_halt): Map physical addresses.
* i386/i386at/acpihalt.h: New file.
* i386/grub/glue.h: Some glue macros.
* i386/grub/i18n.h: Stub out i18n.
