include: add version_compare helper function
Backported from X.org: commit 0df871cf34ee5f1a85586206027de9b02fb364ec Author: Robert Ancell <robert.ancell@canonical.com> Date: Thu May 22 10:43:52 2014 +1200 Fix overflow checking extension versions The easiest way to check for the version of an extension is to send the maximum possible version numbers in the QueryVersion request. The X server overflows on these as it assumes you will send a reasonable version number.

Switch the few users of manual version switching over to the new function.
