* Fully convert to pkginstall framework by properly using OWN_DIRS*
to manage required directories during package installation and
deinstallation.
* Drop the need to explicitly set PREFIX in the package Makefiles. We
now install into ${LOCALBASE} like all other pkgsrc packages and use
symlinks and file copies to put the right files into ${IMDICTDIR}.
* Change default dependency relationship in sj3-lib/buildlink3.mk to a
build dependency since it the package only installs headers and a
static library archive.
* Move some important setup instructions from the DESCR file to MESSAGE
files so that the admin will see them at package installation.
* Rewrite the sj3 rc.d script so that all necessary directories are
created before the daemon is started.
* Miscellaneous touch ups to the DESCR and MESSAGE files.
Bump the PKGREVISIONs on the sj3* packages.
