[PATCH 6/7] virDomainNetDefFormat: Simplify @sourceAttrBuf handling for some types of VIR_DOMAIN_NET

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

For VIR_DOMAIN_NET_TYPE_{SERVER,CLIENT,MCAST,UDP} we need to put
(optionally) 'address' attribute and 'port' attributes of
<source/> element. But the way we currently do that is
particularly verbose. It can be shortened using
virBufferEscapeString().
