Mk/*: Build with a clean environment

Both our make and gmake use the MAKEFLAGS environment variable but the
values aren't compatible and the latest version of gmake complains about
that.  To rule out that any environment variable can cause problems like
this, add a new command SETENVI=/usr/bin/env -i that clears the
environment, and use it to run upstream build systems with a clean
environment.

Introduce a new variable WRK_ENV that contains the environment to use
with SETENVI in all targets that run upstream build commands.  Variables
that are common between CONFIGURE_ENV and MAKE_ENV could be moved to
WRK_ENV but for now it just contains a minimal environment:

HOME=${WRKDIR}: Fixes USES=elixir ports that were using the user's HOME.

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.

Approved by:		portmgr (tcberner)

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.

Add USES=xorg USES=gl, ports categories g

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

Change USE_GL to become USES=gl.

Change USE_GL to become USES=gl.  You still need to specify USE_GL as well,
to specify which gl components you need, such as egl glesv2 glut glu glw gl.
Only specifying USE_GL is supported for now, to ease in transition.  It is
however deprecated, and will be removed eventually.
Specifying USES=gl without USE_GL is an error.
USE_GL=yes is also deprecated, but supported for now.  It implies USE_GL=glu.

Fix fallout from this change.

The goal of this project is to add Cell Shading capabilities to the Quake III
engine with Real-time performance.

In order to provide such feature we have decided to use Kuwahara filter.
Kuwahara filter is a noise-reduction filter that preserves edges.

It uses four subquadrants to calculate the mean and variance and chooses the
mean value for the region with the smallest variance.

To increase the hand-painted effect we have decided to apply a simple blur
filter to reduce hard-edges on textures and increase the flatness effect.

To produce the cell shading effect we use no graphics card shaders, so our
implementation could run with almost any gfx card. The edge effect is produced
by painting backface polygons with a thick wireframe without textures and
repaint all the scene, but this time, with textures.

We have also implemented a different algorithm (we call it White Texture),
which uses white textures. It looks like this and this, you can set the
console variable r_celshadalgo to 2, and load another map, or run using the
appropiate link that came with the release.
