[PATCH] xfree86: Move definition of xf86OptionPtr into separate header file

The pile of spaghettis that is the xfree86 include dependencies make it
rather hard to have a single typedef somewhere that's not interfering with
everything else or drags in a whole bunch of other includes.

Move the xf86OptionRec and GenericListRec declarations into a separate
header.

I found compiler errors on RHEL yesterday because of this patch:
http://lists.freedesktop.org/archives/xorg-devel/2011-August/024353.html
it introduces a few duplicate typedefs that gcc 4.6 will cope with without
warnings but cause compiler errors. Given that the xfree86 includes are 
a bit hard to handle, this was the simplest way of fixing them. I'll squash
this in with the above patch before requesting the pull on it.
