Proof-of-Concept port of vhost-user-input written in Rust

• Device creates a UNIX socket to listen on
• vhost-user-input successfully launches a VhostUserDaemon and implements VhostUserInputBackend
• Can also be identified through QEMU
  • QEMU is able to ping the features() and protocol_features() methods
  • QEMU is successfully able to invoke get_config() and set_config() methods on the vhost-user-input device
  • Following the above, execution fails due to: qemu-kvm: Received bad msg size
    • most likely due to either invalid VirtioInputConfig default values
    • or due to how the structs are converted to a slice through std::slice::as_raw_parts
