commit a878815969063bef256295edd5dfb65cc22e51f3

    examples: support no content-length in http-client.js
    
    Adjust the code path where we read the HTTP content, demonstrating
    `Gio.OutputStream.splice()` which can handle the case where there is no
    `content-length` header in an HTTP response.
    
    fixes #498
