glvis@3.3: new package (#7166)

* glvis@3.3: new package

* mesa-glu: now provides 'glu' (GL Utility library)

* openglu: add package, provides glu

* [GLVis] Use MakefilePackage as base. Add 'develop' version.

Small tweaks in the makefile arguments.

* [GLVis] Locate the X11, GL and GLU libraries within their respective
prefixes. Set the C compiler in the makefile arguments.

* [GLVis] Fix a bug: the same variable was used for two different things.

* [libx11] Add the libs property

* [OpenGL] Add the libs property

* [OpenGLU] Add the libs property

* [GLVis] Use the libs properties of libx11, opengl, and openglu

+    #
+    # The following procedure should be used to verify security when a
+    # new version is added:
+    #
+    # 1. Verify that no checksums on old versions have changed.
+    #
+    # 2. Verify that the shortened URL for the new version is listed at:
+    #    http://glvis.org/download/
+    #
+    # 3. Use http://getlinkinfo.com or similar to verify that the
+    #    underling download link for the latest version comes has the
+    #    prefix: http://glvis.github.io/releases
+    #
+    # If this quick verification procedure fails, additional discussion
+    # will be required to verify the new version.
