The goals of this series is to provide more flexibility to external
backends to implement their specific vhost-user request handling
without having to patch vhost-user library.

First patch implements a new API for external backend to advertize
its specific protocol features to vhost-user master.

Second patch ensures a request not handled by the vhost-user library
but by the external backend only will not be treated as an error or
make the vhost lib to crash.

Changes in RFC v2:
==================
 - Fix build & git message
 - Add new enum for not handled messages & remove skip_master (Ilya)

Maxime Coquelin (2):
  vhost: add API to set protocol features flags
  vhost: support requests only handled by external backend
