Marcel Apfelbaum 3ef9622182 machine: Conversion of QEMUMachineInitArgs to MachineState
Total removal of QEMUMachineInitArgs struct. QEMUMachineInitArgs's fields
are copied into MachineState. Removed duplicated fields from MachineState.

All the other changes are only mechanical refactoring, no semantic changes.
