[libvirt] [RFC PATCH 2/4] Extend the domain internal structure to manage dependency devices



A new field has been added in the internal domain definition
(virDomainDeviceDef), in order to store the list of dependencies a domain
refers to.

The informations stored about one dependency are:
    - the absolute path of the XML description
    - the name of the domain

These informations are needed to propagate different signals across the
dependency relation.
