[PATCH xserver 07/13] glx: Use __glXInitExtensionEnableBits in all backends

On xquartz this enables SGI_make_current_read, which is a mostly
harmless lie as CGL doesn't implement it, as well as SGIX_pbuffer, which
is fine because no pbuffer-enabled configs are created.

On xwin this enables SGIX_pbuffer and ARB_multisample in all cases.
Again this is harmless if the backend doesn't support the features,
since no fbconfigs will be created to expose them.

It also adds SGIX_visual_select_group to both xquartz and xwin.
Amusingly, both were filling in the appropriate field in the fbconfig
already.
