[PATCH v4 0/6] virtio: cleanup vhost-user-generic and reduce c&p

["Alex Bennée" <alex.bennee@linaro.org>]

A lot of our vhost-user stubs are large chunks of boilerplate that do
(mostly) the same thing. This series continues the cleanups by
splitting the vhost-user-base and vhost-user-generic implementations.
After adding a new vq_size property the rng, gpio and i2c vhost-user
devices become simple specialisations of the common base defining the
ID, number of queues and potentially the config handling.

I've also added Manos' vhost-user-sound while I was at it.

Changes
-------

I've dropped the F_TRANSPORT work from this series to keep this small
and ready to merge. The changes for F_TRANSPORT are a bit more
invasive and still need a bit of debugging but I wanted to get this
stuff merged now.

  virtio: split into vhost-user-base and vhost-user-device
  hw/virtio: derive vhost-user-rng from vhost-user-base
  hw/virtio: derive vhost-user-gpio from vhost-user-base
  hw/virtio: derive vhost-user-i2c from vhost-user-base
  docs/system: add a basic enumeration of vhost-user devices

Manos Pitsidianakis (1):
  hw/virtio: add vhost-user-snd and virtio-snd-pci devices
