[libvirt] [PATCH 3/3] Move virEmitXMLWarning into xml.h

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

The virEmitXMLWarning function should always have been in
the xml.[hc] files, and should use virXML as its name
prefix

* src/util/util.c, src/util/util.h: Remove virEmitXMLWarning
* src/util/xml.c, src/util/xml.h: Add virXMLEmitWarning
