Title: qemu: 2.0.0 -> 2.1.0

Additionally, add support for more external features as well as more
sound system types.

This has been built locally and run under libvirt but not tested using the nixos test suite. If someone could run the VM tests to make sure everything works that would be helpful as I am limited on computing resources at the moment.
