Subject: Create a struct for X11 state

Will be used for common data between X11 VOs. The main reasons for
making it a separate struct rather than extra fields in the main VO
struct are that some field definitions need X headers and that the code
keeps basic X state such as the display connection over opening and
closing of individual VOs.
