Ensure that soft updates are not enabled by default when using mdmfs(8)

When soft updates began being enabled by default that change carried

that they are only enabled in mdmfs(8) when requested with the -U flag.

Add search of LOCALBASE/share/calendar for calendars supplied by a port.

Calendar files in LOCALBASE override similarily named ones in the base
system. This could easily be changed if the base system calendars should
have precedence, but it could lead to a violation of POLA since then the
port's files were ignored unless those in base have been deleted.

There was no definition of _PATH_LOCALBASE in paths.h, but verbatim uses
of /usr/local existed for _PATH_DEFPATH. Use _PATH_LOCALBASE here to ease
a consistent modification of this prefix.

include: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

libkvm: support access to vmm guest memory, allow writes to fwmem and vmm

This change consists of two parts:
- allow libkvm to recognize /dev/vmm/* character devices as devices that
provide access to the physical memory of a system (similarly to /dev/fwmem*)
- allow libkvm to recognize that /dev/vmm/* and /dev/fwmem* devices provide
access to the physical memory of live remote systems and, thus, the memory
is writable

As a result, it should be possible to run commands like
$ kgdb -w /path/to/kernel /dev/fwmem0.0
$ kgdb /path/to/kernel /dev/vmm/guest

Add sbin and /usr/local directories to _PATH_DEFPATH.

Set _PATH_DEFPATH to
/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin. This is the
path in the default class in the default /etc/login.conf,
excluding ~/bin which would not be expanded properly in a string
constant.

For normal logins, _PATH_DEFPATH is overridden by /etc/login.conf,
~/.login_conf or shell startup files. _PATH_DEFPATH is still used as a
default by execlp(), execvp(), posix_spawnp() and sh if PATH is not set, and
by cron. Especially the latter is a common trap (most recently in PR
204813).

- Add vnode-backed swap space specification support. This is enabled when
device names "md" or "md[0-9]*" and a "file" option are specified in
/etc/fstab like this:

md none swap sw,file=/swap.bin 0 0

- Add GBDE/GELI encrypted swap space specification support, which
rc.d/encswap supported. The /etc/fstab lines are like the following:

/dev/ada1p1.bde none swap sw 0 0
/dev/ada1p2.eli none swap sw 0 0

.eli devices accepts aalgo, ealgo, keylen, and sectorsize as options.

swapctl(8) can understand an encrypted device in the command line
like this:

# swapctl -a /dev/ada2p1.bde

- "-L" flag is added to support "late" option to defer swapon until
rc.d/mountlate runs.

- rc.d script change:

rc.d/encswap -> removed
rc.d/addswap -> just display a warning message if $swapfile is defined
rc.d/swap1 -> renamed to rc.d/swap
rc.d/swaplate -> newly added to support "late" option

These changes alleviate a race condition between device creation/removal
and swapon/swapoff.

Finally nuke auth.conf, nine years after it was deprecated. The only
thing it was still used for was to set the "global default" password
hash. Since the stock auth.conf contained nothing but comments, the
global default was actually the first algorithm in crypt(3)'s list,
which happens to be DES; I take the fact that nobody noticed as proof
that it was not used outside of crypt(3).

The only other use in our tree was in the Kerberos support code in
in tinyware's passwd(1). I removed that code in an earlier commit;
it would not have compiled anyway, as it only supported Kerberos IV.

The auth_getval() function is now a stub that always returns NULL,
which has the same effect as a functional auth_getval() with an
empty auth.conf.

Add the BSD-licensed Citrus iconv to the base system with default off
setting. It can be built by setting the WITH_ICONV knob. While this
knob is unset, the library part, the binaries, the header file and
the metadata files will not be built or installed so it makes no impact
on the system if left turned off.

This work is based on the iconv implementation in NetBSD but a great
number of improvements and feature additions have been included:

- Some utilities have been added. There is a conversion table generator,
which can compare conversion tables to reference data generated by
GNU libiconv. This helps ensuring conversion compatibility.
- UTF-16 surrogate support and some endianness issues have been fixed.
- The rather chaotic Makefiles to build metadata have been refactored
and cleaned up, now it is easy to read and it is also easier to add
support for new encodings.
- A bunch of new encodings and encoding aliases have been added.
- Support for 1->2, 1->3 and 1->4 mappings, which is needed for
transliterating with flying accents as GNU does, like "u.
- Lots of warnings have been fixed, the major part of the code is
now WARNS=6 clean.
- New section 1 and section 5 manual pages have been added.
- Some GNU-specific calls have been implemented:
iconvlist(), iconvctl(), iconv_canonicalize(), iconv_open_into()
- Support for GNU's //IGNORE suffix has been added.
- The "-" argument for stdin is now recognized in iconv(1) as per POSIX.
- The Big5 conversion module has been fixed.
- The iconv.h header files is supposed to be compatible with the
GNU version, i.e. sources should build with base iconv.h and
GNU libiconv. It also includes a macro magic to deal with the
char ** and const char ** incompatibility.
- GNU compatibility: "" or "char" means the current local
encoding in use
- Various cleanups and style(9) fixes.
