[xlib] Make xlib_display_t private and rename xlib_screen_info_t
The issue Joonas was trying to solve was the unwanted inclusion of the inlines via cairo-freelist-private.h. Unwittingly he included cairoint.h from cairo-xlib-private.h instead, a far more heinous crime as that causes the boilerplate to try to use the hidden, private symbols. Instead we resolve this issue by making the cairo_xlib_display_t structure private to cairo-xlib-display.c and provide functions to manipulate the abstract data type. Whilst in the vicinity, we rename cairo_xlib_screen_info_t to cairo_xlib_screen_t for consistency and cleanliness.
