Log message:
Remove redundant NO_CHECKSUM and EXTRACT_ONLY definitions.

Log message:
Mark as meta-package.

Log message:
Add DESTDIR support.

Log message:
* If PLIST_SRC is explicitly set to an empty value in a package Makefile,
  then automatically generate a PLIST that says "${PKGNAME} has no files".

* If PLIST_SRC and GENERATE_PLIST are not set in a package Makefile,
  and no PLIST files exist, then fail during the package build with
  PKG_FAIL_REASON.

* Remove "intentionally empty" PLISTs again.

Now, the easy way to say that a package installs no files is to just
add the following to the package Makefile:

	PLIST_SRC=	# empty

Log message:
Re-add "intentionally empty" PLISTs for meta-packages and other packages
that directly manipulate empty PLISTs.

Modify plist/plist.mk so that if the PLIST files are missing and no
GENERATE_PLIST is defined, then the package fails to build.

Log message:
Remove empty PLISTs from pkgsrc since revision 1.33 of plist/plist.mk
can handle packages having no PLIST files.

Log message:
Split out deinstall portions of INSTALL scripts into DEINSTALL scripts.
This avoids the need for a confusing line of the form:

	DEINSTALL_TEMPLATE+=	path/to/INSTALL

in the package Makefile, and actually removes the need to specify it
altogether since by convention, the existence of the DEINSTALL script
is enough to add it to DEINSTALL_TEMPLATE.

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.
