The code below looks good, but I don't think we should define macros
prefixed with WL_ since that'd be something wayland might do.
I just sent a patch (CC:ed you on it) that makes scanner.c generate
these for us, just sa we do with events. If we don't go with generating
the _SINCE_VERSION macros for requests, then you should probably prefix
them in some way.
