[Qemu-devel] [PATCH v4 11/33] pc: Register machine classes directly instead of using QEMUMachine

[Eduardo Habkost <ehabkost@redhat.com>]

This is a (mostly) blind and mechanical conversion of the PC QEMUMachine
definitions to corresponding class registration code.

Existing duplication and unnecessary complexity on macro/function reuse
is being kept, to keep the conversion simple to review. The complexity
and duplication will be gradually removed by the next patches.

Changes v1 -> v2:
 * Remove unused PC_DEFAULT_MACHINE_OPTIONS macro leftover
 * Use machine_class_register_global_props_array()
 * Rebase on top of Michael's pci tree
 * Eliminate qemu_register_pc_machine(), as it is not needed anymore
Changes v2 -> v3:
 * Make static TypeInfo structs const
