    src: add native URL class

    Adds a URL native class for use within the node.js c/c++
    code. This is primarily intended to be used by the eventual
    ES6 modules implementation but can be used generally wherever
    URL parsing within the c/c++ may be necessary.

    ```c
    URL url1("http://example.org");
    URL url2("foo", "http://example.org/bar");
    URL url3("baz", &url2);
    ```

    While we're at it, reduce reliance on macros to simplify impl.
