I wonder why go from QEMUMachine* to QemuMachine*? I don't spot a name
clash, and keeping QEMU like we use PCI or USB would make the correct
spelling clearer.

Cleaning up that trailing white line is good. Might it make sense to
move the new line to above null-machine.o though?

My preference would be to just use machine_ prefix.

No-op functions could be left out here and added once needed.
