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.
