mesa: Remove GL_MESA_resize_buffers

Commit bab755a made the implementation a no-op, and it was only ever
enabled by software rasterizers.

v2: Move the spec into docs/specs/OLD since it's now obsolete
    (squashed patch from Andreas Boll)

+    Mesa 2.2 or later is required.
+
+Overview
+
+    Mesa is often used as a client library with no integration with
+    the computer's window system (an X server, for example).  And since
+    Mesa does not have an event loop nor window system callbacks, it
+    cannot properly respond to window system events.  In particular,
+    Mesa cannot automatically detect when a window has been resized.
+
+    Mesa's glViewport command queries the current window size and updates
+    its internal data structors accordingly.  This normally works fine
+    since most applications call glViewport in response to window size
+    changes.
+
+    In some situations, however, the application may not call glViewport
+    when a window size changes but would still like Mesa to adjust to
+    the new window size.  This extension exports a new function to solve
+    this problem.
+
+New Procedures and Functions
+
+    void glResizeBuffersMESA( void )
+
+New Tokens
+
+    none
+
+Additions to the OpenGL Specification (no particular section)
+
+    The glResizeBuffersMESA command may be called when the client
+    determines that a window has been resized.  Calling
+    glResizeBuffersMESA causes Mesa to query the current window size
+    and adjust its internal data structures.  This may include
+    reallocating depth, stencil, alpha and accumulation buffers.
+
+Additions to the AGL/GLX/WGL Specifications
+
+    None
+
+Errors
+
+    INVALID_OPERATION is generated if glResizeBuffersMESA is called between
+    Begin and End.
+
+New State
+
+    None.
+
+New Implementation Dependent State
+
+    None.
