installboot(8): fix up markup

Don't overuse .Sy - when everything is highlighted, nothing is.  Use
.Ic for options &c to get correct PostScript output (both are bold in
plain text).

Use Aq Ar inside .Pa, as both Pa and Ar are rendered as underscored
text in plain text output, and the distinction is lost.

Don't set examples in bold, but give them .Pp space around - they are
much easier to read this way.

PR/57909: Jan-Benedict Glaw: Don't include (build) timestamp when doing a
reproducible build
fix usage string, improve error handling.
add missing chunk for repro-build. fix gcc warnings.
avoid stringop truncation, fix copyright string to prevent assembler warnings.

Fix build as a tool (Jan-Benedict Glaw)

Fix integer overflow of strtol(3) for "loadpoint" address on ILP32 hosts.

This strtol(3) was introduced in rev 1.12 for PR/57909 after netbsd-10,
but it returns LONG_MAX (0x7FFFFFFF) for 0xFFF00000 on ILP32 hosts and
the wrong loadpoint causes "NOT ENOUGH MEMORY" error by the BOOTROMs
on loading uboot.lif on (at least) my 9000/360 and 9000/425t.

Misc cosmetic changes for mostly readability.
- KNF and add some newlines per blocks
- define and use proper bintobcd() macro
- make local functions and variables static

The same uboot.lif binaries are generated.

Rename ${PROGAOUT} -> ${PROGELF} to reflect reality.
Use proper signedness for the LIF file system data structures.

Ancient 4.3BSD used short and int for location, file size, file type,
and addresses etc. but all of them should be unsigned.

Also rename several variables and add comments for readability.
The LIF file system info can be found in "The HPDir Project" page:
https://www.hp9845.net/9845/projects/hpdir/
The same uboot.lif binaries are generated.

Add a preliminary CD boot support to uboot for preparation of PR/54455.
Briefly tested on mame, but not enalbed yet.

Recognize SCSI CD-ROM devices as a booted device properly.

Necessary for PR port-hp300/54455, to boot an md root root RAMDISK

kernel from CD-ROM without "WARNING: can't find match for bootdev:"
prompt.

Sync with src/sys/arch/hp300/stand/mkboot/volhdr.h rev 1.6.
https://mail-index.netbsd.org/source-changes/2024/05/07/msg151195.html

Use proper signedness for the LIF file system data structures.
mkboot should use this MI <sys/bootblock.h> and volhdr.h should
be removed soon.

Use MI <sys/bootblock.h> to refer LIF filesystem structures.
This should have been done when LIF definitions were initially added
to <sys/bootblock.h> for MI installboot(8).

Enable SUPPORT_CD on uboot.

Make cd9660_util.c usable in userland tools like installboot(8).

This was partially done for src/distrib/cdrom/macppc_installboot,
but more strict prototypes are necessary for native binary builds.

Install cd9660 related system headers for tools installboot(8) builds.

Reorder function prototypes per source files.

Add cd9660 support to search a bootloader file in the target file system.

Also add CD boot support for hp300, using a bootloader file in cd9660 fs.
This is a tool's part to close PR/54455.

HP 9000/300 machines read LIF directory entry allocated after
the LIF volume header at the top of the boot disk during bootstrap,
and a bootstrap file must be contiguously allocated on the disk
due to limitation of the LIF specification.

Current NetBSD/hp300's bootloader is larger than ~80KB so we have
to prepare a special 'boot' partition for FFS (that has only 8KB (ffsv1)
or 32KB (ffsv2) spaces) disks to put such a large bootloader.

On the other hand, on ISO9660 fs all files are allocated contiguously
so we can specify a bootloader file in the target ISO9660 directly
in the LIF directory entry.

Note we can simply use the existing "append" option to create bootable
CD ISO for hp300, but it looks some emulators (at leaset MAME) reject
such non-standard ISO files, i.e. with an appended bootloader file at
the end of the image.

Put a RAMDISK kernel and SYS_UBOOT into hp300 installcd to make it bootable.

This should finally close PR/54455.

Fix tools build errors on Cygwin.

Appease warnings on building tools/installboot on Cygwin.

Invert the flag bits to control module loading: rename
LOADMODULES->NOMODULES and READBOOTCONF->NOBOOTCONF.
This way, the default value (0) wired into old bootxx_* and installed
to file systems remains valid and we avoid problems on partial updates.

On i386/amd64, define two flag bits in the boot parameters which control
whether modules are loaded and whether boot.cfg is evaluated, and
set both to "off" per default in the PXE bootloader.
Extend "installboot" to toggle the bits.
This way, pxeboot works with existing dhcp server setups (and as
described in the manpage) out of the box. Also, boot.cfg reading
involves a stat() call which is horribly inefficient with the
TFTP pseudo file system.

A boot block on alpha is always little endian, so read and store values
in little endian via le64toh() and htole64() in ALPHA_BOOT_BLOCK_CKSUM().
Fixes installboot(8) (and future endian-aware disklabel(8)) for alpha
on big endian machines.

_NETBSD_SOURCE, which is incompatible with the tool build.

Pullup rev 1.27 (requested by dsl in ticket #198)

Add offset of old i386 mbr bootsel structure.

Add offset of old i386 mbr bootsel structure.

#include <sys/cdefs.h> to get the definition of __packed.
(Some files which include this file may not have done that.)

Use __packed instead __attribute__((__packed__))

Move mbr_bootsel from offset 404 to offset 400 in struct mbr_sector to
leave 4 bytes for the Windows NT Drive Serial Number (DSN) at 440-443
(as mbr_sector.mbr_dsn).

Ensure that all the MBR & PBR code reserves space for mbr_sector.mbr_dsn.

Leave the bootsel magic number at 444-445 as mbr_sector.mbr_bootsel_magic
(instead of mbr_sector.mbr_bootsel.mbrbs_magic), but use 0xb5e1 (MBR_BS_MAGIC)
instead of 0xaa55 (MBR_MAGIC) to indicate that this change has occurred.

Rework MBR_BS_NEWMBR to mean "mbr_bootsel has moved to 400".

Modify fdisk(8) to automatically relocate the mbr_bootsel from 404 to 400
if mbr_bootsel_magic is the old value (0xaa55), and unset MBR_BS_NEWMBR
to flag that new mbr_bootsel code must be used if updating the MBR.


These changes fixes a problem where Windows 2000 or Windows XP would corrupt
the last 3 bytes + NUL of MBR partition 3's bootsel name if the bootsel name
was 5 characters long, replacing bytes 6-9 with the DSN.
Also, by explicitly reserving the space for the DSN we prevent problems in the
future if non bootsel MBR or PBR code had other information at bytes 440-443.

Add a short key translation map for the boot code.
Usage:
	cp = strchr(bp->bp_keymap, c);
	if (cp != 0 && cp[1] != 0)
		c = cp[1];

Add some notes about the layout of the master/partition/floppy boot record.

Be consistent with "#define<tab>" in previous change.

Add hp300 LIF definitions

move structs nextstep_disklabel/cpu_partition and appendant #defines
to sys/sys/bootblock.h

use uint8_t instead of char for bp_password[]

Make X86_BOOT_MAGIC_* available when ASSEMBLER defined.

Overhaul MBR handling (part 1):

<sys/bootblock.h>:
    *	Added definitions for the Master Boot Record (MBR) used by
	a variety of systems (primarily i386), including the format
	of the BIOS Parameter Block (BPB).
	This information was cribbed from a variety of sources
	including <sys/disklabel_mbr.h> which this is a superset of.

	As part of this, some data structure elements and #defines
	were renamed to be more "namespace friendly" and consistent
	with other bootblocks and MBR documentation.
	Update all uses of the old names to the new names.

<sys/disklabel_mbr.h>:
    *	Deprecated in favor of <sys/bootblock.h> (the latter is more
	"host tool" friendly).

amd64 & i386:
    *	Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
	be consistent with the naming convention of the msdosfs tools.

    *	Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
	and it's confusing to have two functionally equivalent bootblocks,
	especially given that "ufs" has multiple meanings (it could be
	a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).

    *	Rework pbr.S (the first sector of bootxx_*):
	    +	Ensure that BPB (bytes 11..89) and the partition table
		(bytes 446..509) do not contain code.
	    +	Add support for booting from FAT partitions if BOOT_FROM_FAT
		is defined.  (Only set for bootxx_msdos).
	    +	Remove "dummy" partition 3; if people want to installboot(8)
		these to the start of the disk they can use fdisk(8) to
		create a real MBR partition table...
	    +	Compile with TERSE_ERROR so it fits because of the above.
		Whilst this is less user friendly, I feel it's important
		to have a valid partition table and BPB in the MBR/PBR.

    *	Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
	with other platforms.

    *	Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
    	we can boot off FAT partitions.

    *	Crank version of /usr/mdec/boot to 3.1, and fix some of the other
	entries in the version file.

installboot(8) (i386):
    *	Read the existing MBR of the filesystem and retain the BIOS
    	Parameter Block (BPB) in bytes 11..89 and the MBR partition
	table in bytes 446..509.  (Previously installboot(8) would
	trash those two sections of the MBR.)

mbrlabel(8):
    *	Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
	to map the MBR partition type to the NetBSD disklabel type.


Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).

Replace BP_* with I386_BP_FLAGS_*, for consistency with other stuff in
<sys/bootblock.h>
(CONSDEV_ should be converted as well, but that's more intrusive...)

Include <sys/stdint.h> if _STANDALONE (instead of <stdint.h>).
