Add necessary handling code for the new s390 CCW address type to
virDomainDeviceInfo. Further, introduce memory management, XML
parsing, output formatting and range validation for the new
virDomainDeviceCCWAddress type.
Signed-off-by: Viktor Mihajlovski <mihajlov@xxxxxxxxxxxxxxxxxx>
---
V2 Changes
- adapted virDomainDeviceCCWAddressParseXML to handle the new
set of CCW address attributes
V4 Changes
- replace attribute 'schid' with 'devno', same for CCW address
