Code review comment for ~hui.wang/pulseaudio/+git/pulseaudio:ubuntu-xenial

Sorry for the delay, I was on vacation.

It appears during that time someone made a little mess of the pulseaudio packages in ubuntu-xenial. I've fixed that up now, but you'll need to merge my changes from git branch ubuntu-xenial and then resubmit this proposal for ubuntu-xenial.

P.S. The branch for artful is 'ubuntu-artful'.
