* src/qemu_conf.c: fix serial/telnet to use "server" option
        rather than "listen"

        * tests/qemuxml2argvdata/qemuxml2argv-serial-tcp-telnet.args:
        fix the test case too

* tests/qemuxml2argvtest.c (testCompareXMLToArgvFiles): Adjust the
code that creates "actual" output, so that it too produces a
newline-terminated buffer.
* tests/qemuxml2argvdata/*.args: Append a newline to each, via:
for i in $(find|grep '\.args$'); do echo >> $i;done
