[libvirt] [PATCH v2 04/14] qemuBuildInterfaceCommandLine: Move vhostuser handling a bit further
The idea is to have function that does some checking of the
arguments at its beginning and then have one big switch for all
the interface types it supports. Each one of them generating the
corresponding part of the command line.
