spdx: The BSD-2-Clause-NetBSD identifier is obsolete, drop -NetBSD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: use unsigned and %u for rock_ridge_move_count

For diff reduction against NetBSD's makefs. Based on NetBSD git mirror
commit 00991aee8248.

With this change our makefs cd9660 support should be in sync up to
NetBSD commit bdae6c9dc792 ("makefs(8): Nix trailing whitespace.").

makefs: remove unused cd9660 options

Makefs defined "follow-symlinks" and "help" options, but they did
nothing. Remove them.

makefs: remove CD9660MAXPATH #define

It was used only in constructing the host path that contains file
content, which is not related to anything CD9660-specific. PATH_MAX is
the appropriate limit. See OpenBSD commit 299d8950f319.

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.

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)
