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.

graphics/mesa-libs: Bump reverse deps for libglvnd

Per discussion with bapt on helping pkg handle the changing of these
deps and avoiding impossible upgrade senarios.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories m

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

multimedia/libva{,-intel-driver}: clean up

- Add BUILD_DEPENDS to intel driver for wl_drm_interface fix
- Rewrite gettid() to make it easier to maintain
- Update description from upstream
- Drop unused v4l_compat dependency
- Drop unused USES=alias as <alloca.h> is gone
- Drop libGL dependency as intel driver uses libEGL via dlopen on Wayland
- Drop --program-prefix after vainfo moved to libva-utils
- Drop fmake workaround as USES=gmake is used
- Drop -ldl workaround for FreeBSD < 11.2
- Drop RTLD_NODELETE workaround for FreeBSD < 8.0
- Drop GLX_GLXEXT_VERSION workaround for Mesa < 7.8.1
- Drop Created by as the port diverged a lot (even more with Meson)
- Hint intel driver isn't actively developed (but still maintained)
- Clarify libdrm dependency

Make libva and it's drivers install modules in the standard location
PREFIX/lib/dri.

This is the same location where other ports(mesa) install drivers,
so that everything works out of the box.

- Remove STRIP option. The STRIP variable needs special handling
  from bsd.port.mk. Using it as an option breaks DEBUG build and
  prevents installation of stripped binaries.
- Bump PORTREVISION due to change in installed binaries (stripped
