Log message:
Remove gnome-libs from pkgsrc. All its dependencies were already removed.

Log message:
libXt is needed for depending packages.

Log message:
Modular Xorg support.

Log message:
Mechanically replace all includes of buildlink3.mk of the following
packages with the modular Xorg equivalent. Those are falling back
to the old location by default, so this commmit doesn't change
dependencies.

graphics/xpm ==> x11/libXpm
fonts/Xft2 ==> x11/libXft
x11/Xfixes ==> x11/libXfixes
x11/xcursor ==> x11/libXcursor
x11/Xrender ==> x11/libXrender
x11/Xrandr ==> libXrandr

Log message:
Change the format of BUILDLINK_ORDER to contain depth information as well,
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

For example, "make show-buildlink3" in fonts/Xft2 displays:

	zlib
	fontconfig
	    iconv
	    zlib
	    freetype2
	    expat
	freetype2
	Xrender
	    renderproto

Log message:
Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.

Log message:
Removed the superfluous "quotes" and 'quotes' from variables that don't
need them, for example RESTRICTED and SUBST_MESSAGE.*.

Log message:
Bump BUILDLINK_ABI_DEPENDS.png and PKGREVISION for png-1.2.9nb2 update.

Log message:
Strip ${PKGLOCALEDIR} from PLISTs of packages that already obey
PKGLOCALEDIR and which install their locale files directly under
${PREFIX}/${PKGLOCALEDIR} and sort the PLIST file entries.  From now
on, pkgsrc/mk/plist/plist-locale.awk will automatically handle
transforming the PLIST to refer to the correct locale directory.

Log message:
BUILD_USE_MSGFMT and USE_MSGFMT_PLURALS are obsolete.  Replace with
USE_TOOLS+=msgfmt.
