f869197b76 virtio: assert and ERRLOG for virtio-user dynamic mem allocations
We do not support dynamic memory allocation with the virtio-user
library - it results in SET_MEM_TABLE vhost messages for every
change which is not supported by the vhost target.

Add '-s 256' to vhost fuzz script, to ensure it does not
violate the new restriction.

This is a follow-on patch for issue #2596.

84ac072e2c lib/virtio: eliminate virtio_user_backend_ops
The `vhost_user` socket transport APIs are already in the
same source file, so just call the function directly.

No code logic changes in this commit.

4e6e7eafef lib/virtio: merge vhost_user.c and virtio_user.c into one source file
Similar with NVMe device driver, here `virtio` is a specification
abstraction library, `pci` and `vhost_user` are transports layer,
here we merge vhost_user.c and virtio_user.c into one new source
file `virtio_vhost_user.c` so that to make code more clear.

No logic change, just code movement in this commit.
