Abhishek Bhardwaj 1de3b5aef8 vhost_user: Modify signature of send_ack_message
send_ack_message used to take a module local Result as a parameter. It
doesn't make sense for other modules to use this. This change makes the
method take a bool instead of the aforementioned Result.

BUG=b:194136484
TEST=Compile.

vHost

A pure rust library for vhost-user. This is a fork of rust-vmm/vhost.

vhost Architecture

The vhost-user protocol aims to implement vhost backend drivers in userspace, which complements the ioctl interface used to control the vhost implementation in the Linux kernel. It implements the control plane needed to establish virtqueue sharing with a user space process on the same host. It uses communication over a Unix domain socket to share file descriptors in the ancillary data of the message.

The protocol defines two sides of the communication, master and slave. Master is the application that shares its virtqueues, slave is the consumer of the virtqueues. Master and slave can be either a client (i.e. connecting) or server (listening) in the socket communication.
