please test patches to make Xos_r.h generated based on configure

[Jeremy C. Reed]

Please see my ticket at https://bugs.freedesktop.org/show_bug.cgi?id=9027

Can you please test these two patches found there for x11proto? And report 
back to me (and let me know your platform too).

Before using patch move Xos_r.h to Xos_r.h.in.

To test fully you may need to build and use some stuff that uses this 
too.

This gets rid of the XUSE_MTSAFE_*API settings to use autoconf instead.

This is from NetBSD pkgsrc and is not from me. But I'd like to get this 
committed officially.

Or do you have any comments for this?

Thank you,

Jeremy C. Reed
