Subject: [PATCH] vfio: move eventfd support code for VFIO_PCI to a separate
 file

The virqfd functionality that is used by VFIO_PCI to implement interrupt
masking and unmasking via an eventfd, is generic enough and can be reused
by another driver. Move it to a separate file in order to allow the code
to be shared.
