[libvirt] [PATCH 1/2 v3] Fix virDomainChrDefParseTargetXML() to parse the target port if available

[Michal Novotny]

Hi,
this is the patch to fix the virDomainChrDefParseTargetXML() functionality
to parse the target port from XML if available. This is necessary for
multiple serial port support which is the second part of this patch.
