    intel: Advertise multisample DRI2 configs on gen >= 6

    This turns on window system MSAA.

    This patch changes the id of many GLX visuals and configs, but that
    couldn't be prevented. I attempted to preserve the id's of extant configs
    by appending the multisample configs to the end of the extant ones. But
    somewhere, perhaps in the X server, the configs are reordered with
    multisample configs interspersed among the singlesample ones.

Reproduce steps:
----------------
1. start X
2. ./bin/glean -r /tmp/logicOp -o -v -v -v -t +logicOp

The bug is in glean, not Mesa. Patch submitted to piglit list:

    glean: Skip multisample configs
    
    Many tests do not adjust their expectations for mutlisampling and hence
    incorrectly fail.
