[libvirt] [PATCH 05/12] parallels: reimplement functions, which change domain state

Thu Oct 23 15:58:09 UTC 2014
Change domain state using parallels SDK functions instead of
prlctl command.
We don't need to send events and update domains in
privconn->domains list in these functions anymore, because
it's done in prlsdkEventsHandler. Each time we do something
with domain, parallels server sends an event,
prlsdkEventsHandler is called and we update cached state
accordingly
