glw: Remove GLw source.

libGLw is an old OpenGL widget library with optional Motif support.
It almost never changes and very few people actually still care about
it, so we've decided to ship it separately.

The new home for libGLw is: git://git.freedesktop.org/mesa/glw/

-This directory contains the source code for SGI's OpenGL Xt/Motif widgets,
-slightly modified by Jeroen van der Zijp to work better with Mesa.
-
-To compile the widget code (producing lib/libGLw.a) cd to the widgets/
-directory and type 'make <config>' where <config> is the system configuration
-you used to compile Mesa (like 'make linux').  This hasn't been tested on
-many systems so let us know if you have trouble.
-
-If you want to make a Linux ELF shared lib instead of the non-shared .a
-file see the notes in the Makefile.
-
-If you want to build with Motif support, edit Makefile.X11, looking
-for the "Motif" information.
-
-The SGI copyright is as follows.
