[libvirt] [PATCH v2] qemu: sound: Support intel 'ich6' model

In QEMU, the card itself is a PCI device, but it requires a codec
(either -device hda-output or -device hda-duplex) to actually output
sound. We set up an hda-duplex codec by default: I think it's important
that a simple <sound model='ich6'/> sets up a useful codec, to have
consistent behavior with all other sound cards.
This is basically Dan's proposal of
<sound model='ich6'>
<codec type='output' slot='0'/>
<codec type='duplex' slot='3'/>
</sound>
without the codec bits implemented.
The important thing is to keep a consistent API here, we don't want some
<sound> models to require tweaking codecs but not others. Steps I see to
accomplishing this when someone gets around to it:
- every <sound> device has a <codec type='default'/> (unless codecs are
manually specified)
- <codec type='none'/> is required to specify 'no codecs'
- new audio settings like mic=on|off could then be exposed in
<sound> or <codec> in a consistent manner for all sound models
