[RFC PATCH 1/4] Add XML description of the new dependency device

[Valentin BOUSSON <v.bousson@xxxxxxxxxxxxxxxxxxxxxx>]

The RNG structure is modified in order a user can instantiate a domain with a
new kind of device. By adding the device sub-tag <domaindependency>, the user
can link to another XML file, describing the domain to depend on.

For example, if a master domains specify in its XML description :
<devices>
    ..
    <domaindependency> ~/slave_domain.xml </domaindependency>
    ...
</devices>

Then, the slave domain (described by the file slave_domain.xml) will be loaded
in the meantime.

The filepath must be absolute, because all the operations are done by the
libvirt daemon.
