[Libvir] [PATCH] remove useless tests before xmlFree

I've just fixed a bug in my useless-if-detecting script, committed in gnulib. Using that new script with today's change adding xmlFree to the list exposed a bunch of useless tests. This first change set removes those tests. Below it is a separate patch that updates gnulib-related files, including that script and vc-list-files. I verified that with these changes "make distcheck" passes. If no one objects, I'll push these in about 12 hours. remove useless tests before xmlFree * src/qemu_conf.c (qemudParseDiskXML, qemudParseInterfaceXML): (qemudParseInputXML, qemudParseDhcpRangesXML): * src/remote_internal.c (doRemoteOpen): * src/storage_conf.c (virStoragePoolDefParseDoc): * src/xm_internal.c (xenXMParseXMLDisk, xenXMParseXMLVif): (xenXMParseXMLToConfig, xenXMAttachInterface): * src/xml.c (virDomainParseXMLDiskDesc, virDomainParseXMLIfDesc): (virDomainXMLDevID): Signed-off-by: Jim Meyering <meyering(a)redhat.com&gt;
