[PATCH 31/37] virDomainNetDefParseXML: Refactor parsing of <virtualport>

[Peter Krempa]

Base whether virtualport is supported for a given interface on a new
variable named 'virtualport_flags' which also configures the parser for
the virtualports subelement and fill it in the appropriate interface
type branches.
