There were a few pitfalls with the way this was previously implemented
because --geometry implicitly depended on --auto-window-resize being
enabled to operate in a few cases. Instead, let's change the logic a bit
so that instead we choose whether or not to reuse the old rc (i.e. don't
resize) and use the wh_valid and xy_valid fields within the m_geometry
struct instead of using x11->geometry_change. This fixes several edge
cases involving setting the position with --geometry when using
--auto-window-resize=no.
