Bug Description:
---------------------
When run the case wincopy, it will return a message: this program requires either GLX 1.3 or GLX_SGI_make_current_read. With EXA, it runs well. I checked the glxinfo of them and find with UXA there is no support of GLX_SGI_make_current_read in glx extension. The diff file is in attachment. 

Reproduce steps:
----------------
1.enable UXA
2.xinit&
3. run xdemo/wincopy.

    dri2: Enable GLX_SGI_make_current_read when the DRI driver supports it.
    
    This matches idr's 82f150d73cc9a7d8eaf7241a51b03af05bcec159 for DRI1.

Thanks Gordon. With the newest code, it now has GLX_SGI_make_current_read support now. Verified with:
