rust: iterator bindings to C code

In this changeset, still made of Rust code only,
we expose the Rust iterator for instantiation and
consumption from C code.

The idea is that both the index and index_get_parents()
will be passed from the C extension, hence avoiding a hard
link dependency to parsers.so, so that the crate can
still be built and tested independently.

On the other hand, parsers.so will use the symbols
defined in this changeset.

    out.write(data + end)
    out.flush()

    """Simple wrapper around dispatch.dispatch()

    Prints command and result value, but does not handle quoting.
    """
    printb(b"running: %s" % (cmd,))
    req = dispatch.request(cmd.split())
