[PATCH v9 00/11] virtio: cleanup vhost-user-generic and reduce c&p + vhost-user-input

[Alex Bennée]

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 and Leo's vhost-user-input
stubs which are based on the same base.

Changes
-------

v9
  - re-base and fix conflicts
  - add Leo's vhost-user-input series

v8
  - scrubbed errant Message-Id

v7
  - various review comments
  - move to async teardown (fixes CI failure)

v6
  - re-base to current master
  - make vhost-user-device abstract
  - mention abstractness in docs

v5
  - addressing comments and tags
  - improved the docs

v4
  - dropped the F_TRANSPORT work for another series
  - added vhost-user-sound
