[libvirt PATCH 10/18] conf: rename and improve virDomainDefFindAudioForSound

[Daniel P. Berrangé <berrange@xxxxxxxxxx>]

The virDomainDefFindAudioForSound only takes a virDomainSoundDefPtr as
its arg, but we want to use the same functionality for VNC graphics.
In addition if audio ID is zero, then we want to return the first
available audio backend.
