GLX: Add a function to change a clients vendor list.
Add a new function, GlxServerExports::setClientScreenVendor, which will change the vendor that handles GLX requests for a screen, but only for requests from a specific client. v2: Increment the GLXVND minor version number. v3: Note the GLXVND version requirement for setClientScreenVendor.
