[Xcb] [PATCH] xfixes: Update to version 5

[Neil Roberts]

Hi,

Here is a patch to update the XFixes support to version 5.

The main incentive to add this is that currently when using Mesa via
EGL, the platform driver will call XFixesQueryVersion with the latest
version that libxcb supports, which is currently 4. That resets the
value that the server thinks the client can support. If the
application then tries to use pointer barriers it will get an X error.

Regards,
- Neil

This adds the two new functions in XFixes version 5 for handling
pointer barriers.
