It was accidentally lost when factoring out __glXDRIdoReleaseTexImage, so this
is a regression fix and should probably be backported to server-1.5-branch.
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.
Under the terms of version 1.1, "once Covered Code has been published
under a particular version of the License, Recipient may, for the
duration of the License, continue to use it under the terms of that
version, or choose to use such Covered Code under the terms of any
subsequent version published by SGI."
FreeB 2.0 license refers to "dates of first publication". They are here

As always, this code has not been tested for conformance with the OpenGL
specification. OpenGL conformance testing is available from
http://khronos.org/ and is required for use of the OpenGL logo in
product advertising and promotion.
- Redo damage naming for more consistency.
- Call post submission functions only where appropriate.
- EXA can now live without it's odd damage workarounds.
GLX is enabled by default, but the current swrast behaviour causes X
to abort with fatal error if the swrast dri library dlopen fails.
Handle the case where the swrast library is not present, and do not
register the GLX extension unless at least one screen has a usable
GL provider.
