Sebastien Boeuf cebfa3cd78 lib: Implement VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS 
Relying on latest vhost version, this commit implements
VHOST_USER_GET_MAX_MEM_SLOTS, VHOST_USER_ADD_MEM_REG and
VHOST_USER_REM_MEM_REG commands from the protocol feature
VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS.

VHOST_USER_GET_MAX_MEM_SLOTS provides the maximum amount of memory
slots that can be supported by the vhost-user backend.

VHOST_USER_ADD_MEM_REG lets the frontend provide a new memory region
that must be mapped by the backend.

VHOST_USER_REM_MEM_REG lets the frontend request for the removal of an
existing memory region that must be unmapped by the backend.

vhost-user-backend

Design

This crate provides convenient abstractions for implementing vhost-user device server backends:

  • A vhost-user backend trait (VhostUserBackend)
  • A public API for the backend to interact with (VhostUserDaemon)
  • An structure including virtio queue related elements (Vring)
  • A worker for receiving queue events and forwarding them to the backend.

Usage

Users of this create are expected to implement the VhostUserBackend trait and to initialize the execution context by instantiating VhostUserDaemon and calling to its start method.
