Upgrade GLX Public License 1.0 to FreeB 2.0.

According to the press release:

    Previous SGI contributions to the free and open source community
    are now available under the new license. These contributions
    include the SGI® OpenGL® Sample Implementation, the GLX™ API and
    other GLX extensions.

    [...]

    "SGI has been one of the most ardent commercial supporters of free
    and open source software, so it was important to us that we continue
    to support the free software development community by releasing our
    earlier OpenGL-related contributions under this new license," said
    Steve Neuner, director of Linux, SGI. "This license ensures that all
    existing user communities will benefit, and their work can proceed
    unimpeded. Both Mesa and the X.org Project can continue to utilize
    this code in free software distributions of GNU/Linux. Now more than
    ever, software previously released by SGI under earlier GLX and SGI
    Free Software License B is free."

"The GLX API" is here read to include the original GLX source release
from:

http://www.sgi.com/products/software/opensource/glx/download.html
ftp://ftp.sgi.com/sgi/opengl/glx/glx1_2.1.tgz

which includes glxext.c as included in XFree86, from which our copies
in glx/ and hw/dmx/glxProxy/ are derived.
