A new machine-specific function "grub_machine_set_prefix" is
        defined. This is called after loading modules, so that a prefix
        initialization can use modules. Also, this change adds an
        intensive debugging feature for the memory manager via the
        configure option "--enable-mm-debug".

        * partmap/gpt.c (gpt_partition_map_iterate): Add one more into
        PART.LEN.

        * kern/sparc64/ieee1275/init.c (abort): Removed.
        (grub_stop): Likewise.
        (grub_exit): New function.
        (grub_set_prefix): Renamed to ...
        (grub_machine_set_prefix): ... this.
        (grub_machine_init): Do not call grub_set_prefix.

        * kern/powerpc/ieee1275/init.c (grub_set_prefix): Renamed to ...
        (grub_machine_set_prefix): ... this.
        (grub_machine_init): Do not call grub_set_prefix.

        * kern/i386/pc/init.c (grub_machine_set_prefix): New function.
        (grub_machine_init): Do not set the prefix here.

        * kern/i386/efi/init.c (grub_machine_set_prefix): New function.

        * kern/efi/init.c: Include grub/mm.h.
        (grub_efi_set_prefix): New function.

        * kern/efi/efi.c (grub_exit): Call grub_efi_fini.
        (grub_efi_get_filename): New function.
        (grub_print_device_path): Renamed to ...
        (grub_efi_print_device_path): ... this.

        * kern/mm.c [MM_DEBUG] (grub_malloc): Undefined.
        [MM_DEBUG] (grub_realloc): Likewise.
        [MM_DEBUG] (grub_free): Likewise.
        [MM_DEBUG] (grub_memalign): Likewise.
        [MM_DEBUG] (grub_mm_debug): New variable.
        [MM_DEBUG] (grub_debug_malloc): New function.
        [MM_DEBUG] (grub_debug_free): New function.
        [MM_DEBUG] (grub_debug_realloc): New function.
        [MM_DEBUG] (grub_debug_memalign): New function.

        * kern/misc.c (grub_abort): Print a newline to distinguish
        the message.

        * kern/main.c (grub_main): Call grub_machine_set_prefix and
        grub_set_root_dev after loading modules. This is necessary when
        setting a prefix depends on modules.

        * include/grub/efi/efi.h (grub_print_device_path): Renamed to ...
        (grub_efi_print_device_path): ... this.
        (grub_efi_get_filename): New prototype.
        (grub_efi_set_prefix): Likewise.

        * include/grub/efi/disk.h: Include grub/efi/api.h, grub/symbol.h
        and grub/disk.h.
        (grub_efidisk_get_device_handle): New prototype.
        (grub_efidisk_get_device_name): Likewise.

        * include/grub/mm.h: Include config.h.

        [MM_DEBUG && !GRUB_UTIL] (grub_debug_free): New prototype.

        * include/grub/kernel.h (grub_machine_set_prefix): New prototype.

        * disk/efi/efidisk.c: Include grub/partition.h.
        (iterate_child_devices): New function.
        (add_device): First, compare only last device path nodes, so that
        devices are sorted by the types.
        (grub_efidisk_get_device_handle): New function.
        (grub_efidisk_get_device_name): Likewise.

        * configure.ac (--enable-mm-debug): New option to enable the
        memory manager debugging feature. This makes the binary much
        bigger, so is disabled by default.
