[libvirt] [PATCHv3 0/3] S390: Finish support for native CCW bus



Originally, QEMU did not implement a native I/O bus for s390.
The initial implementation had a machine type 's390-virtio'
featuring a fully paravirtualized I/O system with an artificial
bus type 'virtio-s390'.
This bus had a number of short-comings, like the need for a
non-standard device discovery mechanism, a limited number
of devices, limited hotplugging capabilites and the lack
of persistent device addresses.
To resolve these issues a new machine type 's390-ccw-virtio' 
has been recently added to QEMU which implementa the native
s390 CCW I/O bus.
Guests with arch='s390x' and machine='s390-ccw-virtio' can
now be defined with up to 262144 virtio devices.

This series adds the support for the s390-ccw-virtio
machine type and the CCW bus to libvirt. 

V2 Changes
 - use an attribute triple cssid, ssid, schid instead of devno
   to better represent the libvirt CCW address structure
 - rebase to current upstream, mainly address qemuCapsXXX rename

V3 Changes
 - skip already acked patches 1/5 and 2/5
 - revert machine-based capabilities
 - use machine definition from domain object
