Re: [libvirt] [PATCH] util: Prepare URI formatting for libxml2 >= 2.9.2

Since commit 8eb55d782a2b9afacc7938694891cc6fad7b42a5 libxml2 removes two slashes from the URI when there is no server part. This is fixed with beb7281055dbf0ed4d041022a67c6c5cfd126f25, but only if the calling application calls xmlSaveUri() on URI that xmlURIParse() parsed. And that is not the case in virURIFormat(). virURIFormat() accepts virURIPtr that can be created without parsing it and we do that when we format network storage paths for gluster for example. Even though virStorageSourceParseBackingURI() uses virURIParse(), it throws that data structure right away. Since we want to format URIs as URIs and not absolute URIs or opaque URIs (see RFC 3986), we can specify that with a special hack thanks to commit beb7281055dbf0ed4d041022a67c6c5cfd126f25, by setting port to -1. This fixes qemuxml2argvtest test where the disk-drive-network-gluster case was failing.
