The new lifecycle patches in xen-unstable added 3 new operations which can
be performed on domains - new, start and delete.  libvirt has had no-op
stub implementations of these APIs for a while & thus we'd enable their
use for Xen 3.0.4 builds. The new APIs are not currently exposed via the
existing SEXPR protocol, and since the new Xen-API protocol is unsupported
tech-preview for 3.0.4 we don't want to re-write against that just yet.

Thus the attached patch adds the 3 neccessary bindings for the SEXPR protocol
to allow the lifecycle functionality to be invoked. It also allows the 'state'
parameter to be specified when listing domains, so we can explicitly request
inactive domains if we know we're running against a 3.0.4 era XenD
