Add SHA512 digests for distfiles for x11 category

Problems found locating distfiles:

        Package py-qt4: missing distfile PyQt-mac-gpl-4.11.1.tar.gz

        Package xview-lib: missing distfile xview3.2p1-X11R6.tar.gz

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
Remove pkgviews: don't set PKG_INSTALLATION_TYPES in Makefiles.

Log message:
Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
Drop imake-check logic from X11 components' builtin.mk.
Always use xorg-cf-files and imake from pkgsrc, replacing xpkgwedge.
Always install man pages, not cat pages when using imake.
Unify the various imake PLIST variables in preparation for dropping.
Adjust xbattbar for the new expectations.

Log message:
Remove @dirrm entries from PLISTs

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Merge cube-native-xorg, so that pkgsrc-current can be used with the native
X.Org found in NetBSD-current.

Thanks a lot to all who helped, especially Matthias Scheler who did
repeated tests on Mac OS X and older versions of NetBSD to make sure the
support for those platforms wouldn't be broken (or at least, not fatally,
as I would still expect a few hiccups here and there, because there is
only so much one can test in such limited time).

On the infrastructure side, this branch brings pkgconfig-builtin.mk, in
order to write very easily new builtin.mk files.  It can actually handle
more than just pkgconfig files, but it will provide a version if it finds
such a file.  x11.builtin.mk has also been made more useful and now all
existing (and future!) native-X11-related builtin.mk files should include
it.

Log message:
The package supports installation to DESTDIR.

Whitespace cleanup, courtesy of pkglint.
Patch provided by Sergey Svishchev in private mail.

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
