Remove the isdn sets from syspkg, now that they have no user left.

Remove dhclient from the base system.

Discussed here:
https://mail-index.netbsd.org/tech-userlevel/2018/06/21/msg011233.html

branches: 1.11.46;
Remove tn3270 from sets

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

branches: 1.9.18;
add missing locale syspkg stuffs.

Remove some more krb4 remnants.

remove sushi

Add missing NetBSD ID tags

Add a Catalan libc message catalog file (plus everything else needed to
track the file). Closes my own PR lib/19498.

add Slovak (sk_SK) locale support.

branches: 1.3.2;
Separate various parts of sushi(8) from the *-sysutil-* packages into new
*-sushi-* packages.

refine i18n stuffs.
- add libc/citrus directory.
this directory contains the common stuffs not only for locale
but also other facilities relating to i18n (e.g. iconv).
- To keep the binary compatibility for the ctype modules easily,
the interface between libc and the modules is simplified.
- For the future integrated extension, module pool is renamed
from "/usr/lib/runemodule" to "/usr/lib/i18n".
In the future, this directory will contain the modules for "iconv",
"collation", etc.
- some cosmetic changes.
- Bug fix for runetype.h; __attribute__((__packed__)) is placed at
the wrong position and it is invalid unintentionally.
But, the all members of the structures seem well-aligned. Thus,
this bug causes no problem, hopefully.

HEADS UP:
- /usr/lib/rumemodule is obsoleted. If you use the multibyte locales,
you need to install /usr/lib/i18n/* from sys/lib/i18n_module .
- The binary compatibility of /usr/share/locale/*/LC_CTYPE is probably kept.
Perhaps, the bug fix about __packed__ mentioned above breaks the
compatibility... Be careful especially on 64bit platforms.

Import NetBSD System Package (syspkg) sypport for the base, comp, etc, games,
man, misc, and text sets (i.e. all non-X11 sets).

This support currently allows two make(1) targets to be executed from
src/distrib/syspkg/sets:

a.) `make register' will register the existing system as packages.
This willl allow the version of software on the current system
to be queried with

PKG_DBDIR=/var/db/syspkg pkg_info

and individual packages to be deleted with

PKG_DBDIR=/var/db/syspkg pkg_delete <pkgname>

b.) `make package' will create binary packages from the existing
system (or from the contents of ${DESTDIR}, if ${DESTDIR} is
set). These packages can be taken to another system, and
installed with

PKG_DBDIR=/var/db/syspkg pkg_add <pkgname>

to update or install specific packages.

The need to explicitly specify the syspkg PKG_DBDIR will be replaced with a
flag for the various pkg tools in the next few days.
