(pupa_util_biosdisk_get_pupa_dev): Use stat instead of lstat.
* fs/fat.c (pupa_fat_read_data): Shift 4 instead of 12 when the
FAT size is 12. The previous value was merely wrong.
* kern/main.c (pupa_main): Don't split the starting message from
newlines.
* kern/term.c (pupa_putchar): Put CR after LF instead of before
LF, because BIOS goes crazy about character attributes in this
case.
* include/i386/pc/util/biosdisk.h: New file.
* util/i386/pc/biosdisk.c: Likewise.
* util/i386/pc/pupa-setup.c: Likewise.
* Makefile.in (INCLUDE_DISTFILES): Added
include/pupa/i386/pc/util/biosdisk.h.
(UTIL_DISTFILES): Added biosdisk.c and pupa-setup.c under the
directory util/i386/pc.
(install-local): Added a rule for sbin_UTILITIES.
(uninstall): Likewise.

[PUPA_UTIL] (pupa_fat_fini): Likewise.
* fs/fat.c [PUPA_UTIL] (pupa_fat_init): Defined. Maybe a better
way should be implemented.
[PUPA_UTIL] (pupa_fat_fini): Likewise.
* disk/i386/pc/biosdisk.c (pupa_biosdisk_call_hook): Increase
the size of NAME for safety.
(pupa_biosdisk_iterate): Search hard disks to 0x90 instead of
0x88.
