This patches introduces two new messages VHOST_USER_GET_INFLIGHT_FD
and VHOST_USER_SET_INFLIGHT_FD to support transferring a shared
buffer between qemu and backend. This shared buffer is used to process
inflight I/O when backend reconnect
Now It can both support split and packed ring. The example code show
how these APIs work and the test has passed.
