This patch fixes bug #7555 and adds add/remove screen support for RENDER.
Previously, Xdmx was not able to attach and detach screens at runtime when the
RENDER extension was enabled. With this patch it can.
Thank you for your time,

fix bug, add addremovescreen support
James, now that this bug is blocking the release bug, it will be addressed
before the 7.2 release. From my initial scan though your patch, it looks good
but I'd like to review it in more detail.
Patch cleaned up and checked into master and server-1.2-branch (for 7.2 release).
