Message:

PDM, Devices, FE, Main: allow size hints without notification for initial hints.
bugref:9482: FE/Qt and Additions/WINNT: move away from -adjust size if...-
This change allows size hints/monitor information to be set in a machine
without generating an IRQ notification, for the purpose of setting the
initial monitor information. It also uses the function for that purpose.
