Alexandre Courbot 6f8f396312 virtio: vhost-user: introduce VhostUserDevice trait ... Most of our VhostUserBackends require an Executor to be constructed, which interferes with our wish to jail them: we want to create the VhostUserBackend before the child process gets forked, but the forking process would render the Executor invalid in the child. Work around this issue by introducing a VhostUserDevice trait which is supposed to include all the device state without its runtime. Once the child process is forked, the device can be converted into a VhostUserBackend using its into_backend() method. This new trait is illustrated using the Console device.
