    std::posix::io::open/1 now returns IO_fd instead of a bare integer

    Fix: make IO_fd not copyable
    Which copy of IO_fd should own the underlying file descriptor? What to
    do about owning copy going out of scope before the non-owning copies?
    Just refuse to copy IO_fd values and be done with it.

    Fix an ancient bug
    Arguments passed to functions were always copied instead of being moved
    due to inverted condition the VM was using to determine when to move and
    when to copy.
    I am *astonished* that it took so long to detect. No less amazing is
    that the first non-copyable type (IO_fd) was introduced only recently,
    several years after the project started.
