`-m32' to CFLAGS.

linking.
* conf/i386-pc.rmk (COMMON_CFLAGS): Add `-m32'.

* include/grub/types.h (grub_host_addr_t, grub_host_off_t)
(grub_host_size_t, grub_host_ssize_t): New types.
(grub_addr_t, grub_off_t, grub_size_t, grub_ssize_t): Make type
dependant of `GRUB_CPU_SIZEOF_VOID_P' instead on
`GRUB_HOST_SIZEOF_VOID_P'.
* include/grub/kernel.h (struct grub_module_header): Type of
member offset changed to `grub_host_off_t'. Type of member size
changed to `grub_host_size_t'.
(struct grub_module_info): Type of member offset changed to
`grub_host_off_t'. Type of member size changed to
`grub_host_size_t'.
* include/grub/normal.h (grub_halt_init): New prototype.
(grub_halt_fini): Likewise.
(grub_reboot_init): Likewise.
(grub_reboot_fini): Likewise.
* util/grub-emu.c: Include signal.h.
(main_env): New global variable.
(grub_machine_init): Ignore SIGINT. Otherwise grub-emu cannot
catch C-c.
(grub_machine_fini): New function.
(main): Call grub_halt_init and grub_reboot_init before
grub_main, and grub_reboot_fini and grub_halt_fini after it.
Call setjmp with MAIN_ENV to go back afterwards.
Call grub_machine_fini right before return.
* include/grub/util/misc.h: Include setjmp.h.
(main_env): New prototype.
* include/grub/kernel.h (grub_machine_fini): New prototype.
* include/grub/i386/pc/biosdisk.h (grub_biosdisk_fini): Likewise.

* util/i386/pc/misc.c: New file.
* conf/i386-pc.rmk (grub_emu_SOURCES): Added
util/i386/pc/misc.c, commands/i386/pc/halt.c and
commands/i386/pc/reboot.c.
All symbols prefixed with PUPA_ and pupa_ are renamed to GRUB_
and grub_, respectively. Because the conversion is trivial and
mechanical, I omit the details here. Please refer to the CVS
if you need more information.
* util/i386/pc/pupa-setup.c (setup): Convert the endianness of
the length of a blocklist correctly.
* util/i386/pc/biosdisk.c (pupa_util_biosdisk_open) [__linux__]:
Use ioctl only if the OS file is a block device.
(pupa_util_biosdisk_open): Don't use ST.ST_BLOCKS, because it is
not very useful for normal files.
* kern/main.c (pupa_set_root_dev): New function.
(pupa_load_normal_mode): Likewise.
(pupa_main): Call those above.
* include/pupa/types.h (pupa_swap_bytes16): Cast the result to
pupa_uint16_t.
