The current implementation seems ready to be promoted to the
main workspace since the device supports test coverage have been
increased and the basic functionality is implemented.
Cargo.lock files both in main and staging workspaces are updated.
Support for VIRTIO_CONSOLE_F_SIZE and VIRTIO_CONSOLE_F_EMERG_WRITE
is still missing.
