Tiwei Bie 4d0cf552d3 vhost-user: introduce shared vhost-user state
When multi queue is enabled e.g. for a virtio-net device,
each queue pair will have a vhost_dev, and the only thing
shared between vhost devs currently is the chardev. This
patch introduces a vhost-user state structure which will
be shared by all vhost devs of the same virtio device.

Gonglei 5da73dabe8 cryptodev: add vhost support
Impliment the vhost-crypto's funtions, such as startup,
stop and notification etc. Introduce an enum
QCryptoCryptoDevBackendOptionsType in order to
identify the cryptodev vhost backend is vhost-user
or vhost-kernel-module (If exist).

At this point, the cryptdoev-vhost-user works.
