v3 because I committed some whitespace only changes in v2. Sorry.

Motivation for this:

After being annoyed for too long with the crackling QEMU produces, I decided
to dive in and try to fix this. 

This has already been tested by several people, please see the corresponding
Reddit-thread:

https://www.reddit.com/r/VFIO/comments/74vokw/improved_pulse_audio_driver_for_qemu/

I presented this to the list a few days ago, but it was in too rough a state,
so I cleaned it up and wrote better commit messages.

This is still missing proper handling for VMState-migration, which I will need a bit of assistance with.
