Fix warnings in grub-emu when compiling with maximum warning options.
* util/hostdisk.c (grub_util_biosdisk_get_grub_dev): Rename one instance
of disk to dsk to avoid shadowing.
Fix warnings in grub-emu when compiling with maximum warning options.
* util/grub-emu.c (ENABLE_RELOCATABLE): New definition.
(grub_arch_modules_addr): Return 0 and not NULL.
* util/misc.c (ENABLE_RELOCATABLE): New definition.
(xstrdup): USe newstr instead of dup.
* util/hostdisk.c (open_device): Don't use partition device when reading
before the partition.
(grub_util_biosdisk_read): Don't read from partition and before the
partition in single operation.
(grub_util_biosdisk_write): Don't write to partition and before the
partition in single operation.
* util/grub.d/10_linux.in: This script does not use any of the
contents of gettext.sh, only the external command `gettext', so stop
sourcing it. (Moreover, gettext.sh isn't necessarily installed in
the same prefix as GRUB.)
* util/grub.d/10_kfreebsd.in: Likewise.
* font/font.c: Include `grub/fontformat.h.
Remove font file format constants.
(grub_font_load): Use the new macros.
* include/grub/fontformat.h: New file.
* util/grub-mkfont.c: Include `grub/fontformat.c'.
(write_font_pf2): Use the new macros.
* conf/common.rmk (grub_mkdevicemap_SOURCES): Add kern/env.c,
kern/err.c, kern/list.c, and kern/misc.c.
* util/deviceiter.c [__linux__]: Define MINOR.
(grub_util_iterate_devices): Add support for DM-RAID disk devices.
* util/mkdevicemap.c (grub_putchar): New function.
(grub_getkey): New function.
(grub_refresh): New function.
(main): Set debug=all if -v -v is used.
* configure.ac: Check for Linux device-mapper support.
* util/hostdisk.c (device_is_mapped): New function.
(find_partition_start): New function, partly broken out from
linux_find_partition and grub_util_biosdisk_get_grub_dev but with
device-mapper support added.
(linux_find_partition): Use find_partition_start.
(convert_system_partition_to_system_disk): Add `st' argument.
Support Linux /dev/mapper/* devices if device-mapper support is
available; only DM-RAID devices are understood at present.
(find_system_device): Add `st' argument. Pass it to
convert_system_partition_to_system_disk.
(grub_util_biosdisk_get_grub_dev): Pass stat result to
find_system_device and convert_system_partition_to_system_disk. Use
find_partition_start.
* util/misc.c (make_system_path_relative_to_its_root): Change the work
around for handling "/" to the correct fix. Fix a memory leak. Use
xstrdup instead of strdup.
* kern/device.c (grub_device_iterate): Allocate new part_ent
structure based on sizeof (*p) rather than sizeof (p->next), to
account for structure padding.
* util/grub-probe.c (probe_raid_level): Return -1 immediately if
disk is NULL, which might happen for LVM physical volumes with no
LVM signature.
