@brief Connects to the X server.
@param displayname: The name of the display.
@param screenp: A pointer to a preferred screen number.
@return A newly allocated xcb_connection_t structure.
Connects to the X server specified by @p displayname. If @p
displayname is @c NULL, uses the value of the DISPLAY environment
variable. If a particular screen on that server is preferred, the
int pointed to by @p screenp (if not @c NULL) will be set to that
screen; otherwise the screen will be set to 0.
Always returns a non-NULL pointer to a xcb_connection_t, even on failure.
Callers need to use xcb_connection_has_error() to check for failure.
When finished, use xcb_disconnect() to close the connection and free
the structure.
