Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.

There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.

The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.

One more small cleanup, forgotten yesterday. Reported by:	lwhsu

Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories x

Add USES=xorg and USES=gl to ports in categories starting with 'x'
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.

Bump PORTREVISION for ports depending on the canonical version of GCC as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3 to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Prepare for powerpc-on-clang by deleting hard-coded tests for architecture as a stand-in for "are we running on gcc".

In some cases we only need to specifically test for "are we on the ancient
base gcc", e.g, the usage of 'pragma'.

While here, in some cases turn off SSE functions more specifically based
on ARCH, and turn off -mtune=generic everywhere.  These are part of a
larger work in progress; these commits are for ports that would have
been touched by the the powerpc-on-clang test regardless.

New port: x11/xsettingsd

xsettingsd is a daemon that implements the XSETTINGS specification.

It is intended to be small, fast, and minimally dependent on other
libraries.  It can serve as an alternative to gnome-settings-daemon
for users who are not using the GNOME desktop environment but who
still run GTK+ applications and want to configure things such as
themes, font antialiasing/hinting, and UI sound effects.
