These are not all the changes, sorry for that.
It seems I don't know how to correctly re-send the patch.

> Changes to correctly initialize the sRGB capability attribute and
> transfer it between XServer and the client. Modifications include
> extension string, transferring visual config attribs and fbconfig
> attribs. Also, attribute is initialized in the modules which do not
> really use it (xquartz and xwin).
> This version advertises both ARB and EXT strings, and initializes
> the capability to default value of FALSE.
