This is the second version of this patch.
The first version was part of a patch series on VFIO AP IRQ.

The goal of this patch is to standardize the device-driver interface
for the VFIO_AP ap_matrix_device to satisfy user-land tools working on
hot-plug (UDEV/LIBVIRT).

Christian Borntraeger reported libvirt looping when a matrix device
was available before the libvirt start.

Marc Hartmayer debugged this and circumvented this in libvirt:
