spdx: The BSD-2-Clause-NetBSD identifier is obsolete, drop -NetBSD

The SPDX folks have obsoleted the BSD-2-Clause-NetBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

makefs: #define Apple Partition bits

NetBSD defines these in sys/bootblock.h, which we don't have. Add local
defintions in cd9660_eltorito.c (as OpenBSD did) to reduce diffs between
the three makefs implementations.

makefs: correct El Torito bood record

The boot catalog pointer is a DWord, but we previously populated it via
cd9660_bothendian_dword which overwrote four unused bytes following it.
See El Torito 1.0 (1995) Figure 7 for details.

makefs: connect cd9660 El Torito EFI boot image system type

Sponsored by: The FreeBSD Foundation

Synchronise with NetBSD's version of EFI handling for El Torito images.

When I implemented my EFI support I failed to check if the upstream version
of makefs in NetBSD had done the same. Override my version with theirs to
make it easier to stay in sync with them in the future.

Allow makefs to properly tag UEFI El Torito boot images. Use them in amd64 ISOs.

UEFI booting requires an EFI System Partition (ESP). On most storage devices
this will be in a specific partition type. To allow booting from CD/ISO
filesystems, UEFI will look for an ESP in the form of a FAT filesystem image
embedded in the image. Historically FreeBSD has added one of these to its
amd64 ISO images but marked it as simply another i386 boot image. Luckily for
us most UEFI implementations are rather forgiving and work this out for us.

This change adds the ability to mark a boot image as being a UEFI image. It
also modifies our ISO generation to use this marking for the UEFI image we
embed.

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

- Write the ISO9660 descriptor after the apm partition entries.
- Fill the needed pmPartStatus flags. At least the OpenBIOS
implementation relies on these flags.

This commit fixes the panic seen on OS-X when inserting a FreeBSD/ppc disc.
Additionally OpenBIOS recognizes the partition where the boot code is located.
This lets us load a FreeBSD/ppc PowerMac kernel inside qemu.

Spelling fixes for usr.sbin/

Sync makefs(8) ISO 9660 support with NetBSD:
o cd9960 -> cd9660
o Move inclusion of sys/endian.h from cd9660_eltorito.c to cd9660.h
since actual user is not cd9660_eltorito.c but iso.h and
cd9660_eltorito.h.

Actually, include order/place of sys/endian.h doesn't matter on
netbsd since it is always included by sys/types.h but it's not
true on other system. This should fix cross build breakage on
freebsd introduced by rev. 1.16 of cd9660_eltorito.c.
Problem reported and fix suggested on twitter.
o Fix fd leaks in error cases. Found by cppcheck.
o RRIP RE length should be 4, not 0
o Apply fixes for PR bin/44114 (makefs(8) -t cd9660 -o rockridge creates
corrupted cd9660fs), iso9660_rrip.c part:
- cd9660_rrip_finalize_node() should check rr_real_parent in node->parent,
not in node itself in RRIP_PL case
- cd9660_rrip_initialize_node() should update only node passed as arg
so handle RRIP_PL in DOTDOT case

Fixes malformed dotdot entries in deep (more than 8 level) directories
moved into .rr_moved dir.

Should be pulled up to netbsd-5.
(no official ISO has such deep dirs, but cobalt restorecd is affected)

Add analogs to the -chrp-boot and -prep-boot options to mkisofs.

Simplify this code somewhat by only writing a 512-byte-sector APM map.
All firmwares can read it, we need to write one anyway for old OF
versions, and if a 512-byte one is present, OS X ignores the 2048-byte one
in favor of it.

Fix boot on old machines (e.g. blue and white G3s) by synthesizing a
512-byte sector map instead unused space in the first 2048-byte sector.

Add support for synthesizing an APM partition map to map Mac PowerPC
bootstrap partitions from the ISO9660 boot catalog. This preserves OS X's
ability to mount the CD, while allowing us a way to provide HFS-ified
bootstrap code for Open Firmware.

Sync with the latest version from NetBSD. It notably addds ISO9660 support.
