Convert to use the features framework.

Log message:
Convert packages that test and use USE_INET6 to use the options framework
and to support the "inet6" option instead.

Remaining usage of USE_INET6 was solely for the benefit of the scripts
that generate the README.html files.  Replace:

	BUILD_DEFS+=	USE_INET6
with
	BUILD_DEFS+=	IPV6_READY

and teach the README-generation tools to look for that instead.

This nukes USE_INET6 from pkgsrc proper.  We leave a tiny bit of code
to continue to support USE_INET6 for pkgsrc-wip until it has been nuked
from there as well.

Log message:
Convert all libnbcompat/buildlink3.mk references to inplace.mk.

Log message:
Make it easier to build and install packages "unprivileged", where
the owner of all installed files is a non-root user.  This change
affects most packages that require special users or groups by making
them use the specified unprivileged user and group instead.

(1) Add two new variables PKG_GROUPS_VARS and PKG_USERS_VARS to
    unprivileged.mk.  These two variables are lists of other bmake
    variables that define package-specific users and groups.  Packages
    that have user-settable variables for users and groups, e.g. apache
    and APACHE_{USER,GROUP}, courier-mta and COURIER_{USER,GROUP},
    etc., should list these variables in PKG_USERS_VARS and PKG_GROUPS_VARS
    so that unprivileged.mk can know to set them to ${UNPRIVILEGED_USER}
    and ${UNPRIVILEGED_GROUP}.

(2) Modify packages to use PKG_GROUPS_VARS and PKG_USERS_VARS.

Log message:
added support for IRIX 5

Log message:
Modify packages that set PKG_USERS and PKG_GROUPS to follow the new
syntax as specified in pkgsrc/mk/install/bsd.pkginstall.mk:1.47.

Log message:
Added appropriate TEST_TARGET.

Log message:
Modify the pkginstall framework so that it manages all aspects of
INSTALL/DEINSTALL script creation within pkgsrc.

If an INSTALL or DEINSTALL script is found in the package directory,
it is automatically used as a template for the pkginstall-generated
scripts.  If instead, they should be used simply as the full scripts,
then the package Makefile should set INSTALL_SRC or DEINSTALL_SRC
explicitly, e.g.:

	INSTALL_SRC=	${PKGDIR}/INSTALL
	DEINSTALL_SRC=	# emtpy

As part of the restructuring of the pkginstall framework internals,
we now *always* generate temporary INSTALL or DEINSTALL scripts.  By
comparing these temporary scripts with minimal INSTALL/DEINSTALL
scripts formed from only the base templates, we determine whether or
not the INSTALL/DEINSTALL scripts are actually needed by the package
(see the generate-install-scripts target in bsd.pkginstall.mk).

In addition, more variables in the framework have been made private.
The *_EXTRA_TMPL variables have been renamed to *_TEMPLATE, which are
more sensible names given the very few exported variables in this
framework.  The only public variables relating to the templates are:

	INSTALL_SRC		INSTALL_TEMPLATE
	DEINSTALL_SRC		DEINSTALL_TEMPLATE
				HEADER_TEMPLATE

The packages in pkgsrc have been modified to reflect the changes in
the pkginstall framework.

Log message:
Recursive revision bump / recommended bump for gettext ABI change.

Log message:
Remove USE_PKGINSTALL from pkgsrc now that mk/install/pkginstall.mk
automatically detects whether we want the pkginstall machinery to be
used by the package Makefile.
