[libvirt] [PATCHv5 1/9] smartcard: add XML support for <smartcard> device

[Jiri Denemark]

> Assuming a hypervisor that supports multiple smartcard devices in the
> guest, this would be a valid XML description:
> 
> <devices>
>   <smartcard mode='host'/>
>   <smartcard mode='host-certificates'>
>     <certificate>/path/to/cert1</certificate>
>     <certificate>/path/to/cert2</certificate>
>     <certificate>/path/to/cert3</certificate>
>   </smartcard>
>   <smartcard mode='passthrough' type='tcp'>
>     <source mode='bind' host='127.0.0.1' service='2001'/>
>     <protocol type='raw'/>
>   </smartcard>
> </devices>
> 
> (As of this commit, the qemu hypervisor will be the first
> implementation, but it only supports one smartcard.)

Same as previously acked v4, except for memory amount in test XMLs.

ACK
