Introduce infrastructure support for SMF.

SMF is the Service Management Facility, the default init system in
Solaris and derivatives since version 10.  This adds "smf" to the list
of supported INIT_SYSTEM types, and makes it the default init system on
platforms where it is available.

Packages can introduce SMF support by providing a manifest file, by
default located in ${FILESDIR}/smf/manifest.xml but manifests under
${WRKSRC} can be used too if the package source includes one.

SMF method scripts are supported too if required, using SMF_METHODS in a
similar manner to RCD_SCRIPTS.

Many parts of the SMF infrastructure are configurable, see mk/smf.mk for
the full details.

#
# Infrastructure support for the Service Management Facility (SMF).  This
# file will be sourced and used if INIT_SYSTEM is set to "smf".
#
# User-settable variables:
#
# SMF_PREFIX
#	This is the global FMRI prefix that will be used in SMF.  The
#	default is "pkgsrc", so the general URI will be of the form
#	"svc:/pkgsrc/<package>:<instance>".
#
# Package-settable variables:
#
# SMF_SRCDIR
#	The source directory containing manifest and method files.  This
#	defaults to ${FILESDIR}/smf and can be set to a location under
#	${WRKSRC} if necessary (i.e. the source includes SMF files).
#
# SMF_NAME
#	This sets the service name part of the FMRI, and defaults to the
#	lower-case string of PKGBASE.
#
# SMF_MANIFEST
#	The name of the XML file under SMF_SRCDIR which is to be used as
#	this package's manifest.  The default name is "manifest.xml"
#
# SMF_INSTANCES
#	The list of instances this manifest provides.  Manifests support
#	multiple instances, the default is a single "default" instance.
#
# SMF_METHODS
#	A list of SMF method scripts available under SMF_SRCDIR with
#	".sh" extensions to be generated and installed.
#
# SMF_METHOD_SRC.<method>
#	Allows you to override the source file name for a particular
#	method, if it does not follow the standard <method>.sh naming.
#
# SMF_METHOD_SHELL
#	The default shell to use in method scripts.

This package has SMF support.  You may use svcadm(1M) to 'enable', 'disable'
or 'restart' services.  To enable the instance(s) for this package, run:

EOF

		cat <<EOF
	/usr/sbin/svcadm enable svc:/@SMF_PREFIX@/@SMF_NAME@:${svc}
EOF

Use svcs(1) to check on service status.  See smf(5) for more information.
