vhost: vhost_user.c code cleanup
This patchesries introduces a set of code redesigns in vhost_user.c.
The goal is to unify and simplify vhost-user message handling. The
patches do not intend to make any functional changes.
v3 changes:
- rebased on top of git://dpdk.org/next/dpdk-next-virtio dead0602
- introduce VH_RESULT_FATAL (Maxime Coquelin)
- vhost_user_set_features return VH_RESULT_FATAL on failure.
This allows keeping the propagate error logic (Ilya Maximets)
- fixed vhost_user_set_vring_kick and vhost_user_set_protocol_features
return VH_RESULT_ERR upon failure
- fixed missing break in case VH_RESULT_ERR (Ilya Maximets)
- fixed a type on the description of 2/5 patch (Maxime Coquelin)
v2 changes:
- Fix the comments by Tiwei Bie
- Keep the old behavior
- Fall through when the callback returns VH_RESULT_ERR
- Fall through if the request is out of range
