Git tree:

This is based on Michael's pci tree.

The basic steps of the conversion (which I forgot to include in the
cover letter):
 * PC_COMPAT_* cleanup, so all follow the same nesting pattern
 * Make MachineClass.compat_props a linked list
 * Mechanical conversion of current code to QOM (like the previous RFC I sent)
 * Elimination of *machine_options() functions
 * Moving global variables to PCMachineClass
 * Common pc_machine_init() function, with a compat_func hook
 * Some piix/q35 duplication elimination, just as a proof of concept of how
   we can proceed
