The patch prepares backend.rs and connection.rs to be platform independent by - depending on base instead on sys_util - using base::Event over sys_util::EventFd - replacing RawFd usage with RawDescriptor and derivatives To keep the noise low, the patch - aliases structs/traits (Event as EventFd) - does not rename variables (say from fd to rd). Note: With this patch the crate/files are not completely platform independent.

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