The following XML:
<serial type='udp'>
<source mode='connect' service='9999'/>
</serial>
is accepted by domain_conf.c but maps to the qemu command line:
-chardev udp,host=127.0.0.1,port=2222,localaddr=(null),localport=(null)
qemu can cope with everything omitting except the connection port, which
seems to also be the intent of domain_conf validation, so let's not
generate bogus command lines for that case.
Additionally, tweak the qemu cli parsing to handle omitted host parameters
for -serial udp
