[RFC PATCH V2 13/18] vfio/pci: Make vfio_pci_set_irqs_ioctl() available

[Reinette Chatre]

vfio_pci_set_irqs_ioctl() is now a generic entrypoint that can
be configured to support different interrupt management backend.
Not limited to PCI devices it can be exported for use by
other virtual device drivers.
