matt335672 689269dcde Fixes some problems with monitor hotplug 
This fixes some monitor hotplug issues with non-GFX codepaths.

1) The server_version_message() was working on an out-of-date
   copy of the client_info. As a result, the X server and the
   window manager did not agree on the number of windows
2) As a result of 1), a memory leak was found in the VNC module.
