[libvirt] [PATCH 8/8] Set the current client identity during API call dispatch

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; When dispatching an RPC API call, setup the current identity to hold the identity of the network client associated with the RPC message being dispatched. The setting is thread-local, so only affects the API call in this thread Signed-off-by: Daniel P.
