virtio 1.0 support for virtio-pci isn't ready yet.
Therefore, this patchset doesn't make any functional changes.
Instead, this simply refactors virtio-pci, splitting legacy
device support code out to a separate file: virtio_pci_legacy.c
For virtio 1.0, all that's left is to add virtio_pci_modern.c
supporting
get_features
finalize_features
get (config)
set (config)
get_status
set_status
reset
setup_vq
del_vq
probe
remove
Most notably, tricky MSI-X vector probing logic stays
in common file: virtio_pci.c. version-specific only has
to code setup/del functions for individual vqs.
Note: this is on top of "virtio 1.0 enhancements"
that I sent earlier.
