Oops, looks like this is a doomed feature. With this change in, a domain
configured with

    <graphics type='spice' autoport='yes'/>

fails to start with error: unsupported configuration: spice TLS port set in
XML configuration, but TLS is disabled in qemu.conf

Apparently tlsPort may be both -1 and 0 depending on autoport value.
