Two long-standing server bugs

I know at least some of that is false; I've done a build-and-reinstall
of the world, including X, many times since 2009 (I didn't even _have_
this hardware in 2009, and a self-hosted rebuild is one of the first
things I do on new hardware).  And I know I did a rebuild in the last
few days, in order to get those two fixes!

Perhaps the NetBSD build machinery isn't updating whatever that is
based on or something.

I can also supply copies of the source in question.  But, really, if
dix/dispatch.c looks similar enough for those patches to apply, then
the bugs are probably present; ProcCreateCursor has changed little
between X11R4 and the X11R7 I was working with, so, unless someone
suddenly started doing drastic rototills, it is probably still pretty
much the same.

That's one reason I wrote that test program I mentioned.
