When a QDev instance is realized, qdev_get_machine() ends up called. In the next commit, qdev_get_machine() will require a "machine" container to be always present. To satisfy this QOM containers design, Implement qdev_create_fake_machine() which creates a fake "machine" container for user emulation. On system emulation, qemu_create_machine() is called from qemu_init(). For user emulation, since the TCG accelerator always calls tcg_init_machine(), we use it to hook our fake machine creation.
