[Libvir] Patch to attach/detach virtual devices on a running domain

[michel.ponceau at bull.net]

This patch adds to Libvirt-0.1.8 the two functions described in my 
preceding mail. It has been tested in our Bull environment.

        Objet : Proposal for virtual devices described in XML

Proposal modified after comments from Daniel P. Berrange:

/* Create a virtual device attachment to backend */
int virDomainAttachDevice(virDomainPtr domain, char *xml);
/* Destroy a virtual device attachment to backend */
int virDomainDetachDevice(virDomainPtr domain, char *xml);
/* @domain: pointer to domain object
* @xml: pointer to XML description of one device
* Returns 0 in case of success, -1 in case of failure. */

The XML is in same form as the part of domain description for a single 
device, either <disk.../disk> or <interface.../interface>.
In Detach function, the device is identified by its target name for 
"disk", and its MAC address for "interface". When the MAC address has not 
been assigned by Libvirt user at device creation, it must be retrieved 
from Xen using virDomainGetXMLDesc function.
