[libvirt] [PATCH for-4.0 v3 1/2] virtio: Helper for registering virtio device types



Introduce a helper for registering different flavours of virtio
devices.  Convert code to use the helper, but keep only the
existing generic types.  Transitional and non-transitional device
types will be added by another patch.

Acked-by: Andrea Bolognani <abologna redhat com>
Signed-off-by: Eduardo Habkost <ehabkost redhat com>
---
Changes v2 -> v3:
* Split into two separate patches (type registration helper
  and introduction of new types)
* Rewrote comments describing each flavour
* Rewrote virtio_pci_types_register() completely:
  * Replaced magic generation of type names with explicit fields in
    VirtioPCIDeviceTypeInfo
  * Removed modern_only field (won't be used anymore)
  * Don't register a separate base type unless it's required by
    the caller
