/**
 * parseUrl
 * Parses the input url.
 *
 * **Note**: This *throws* if invalid urls are provided.
 *
 * @name parseUrl
 * @function
 * @param {String} url The input url.
 * @param {Boolean|Object} normalize Whether to normalize the url or not.
 *                         Default is `false`. If `true`, the url will
 *                         be normalized. If an object, it will be the
 *                         options object sent to [`normalize-url`](https://github.com/sindresorhus/normalize-url).
 *
 *                         For SSH urls, normalize won't work.
 *
 * @return {Object} An object containing the following fields:
 *
 *    - `protocols` (Array): An array with the url protocols (usually it has one element).
 *    - `protocol` (String): The first protocol, `"ssh"` (if the url is a ssh url) or `"file"`.
 *    - `port` (null|Number): The domain port.
 *    - `resource` (String): The url domain (including subdomains).
 *    - `user` (String): The authentication user (usually for ssh urls).
 *    - `pathname` (String): The url pathname.
 *    - `hash` (String): The url hash.
 *    - `search` (String): The url querystring value.
 *    - `href` (String): The input url.
 *    - `query` (Object): The url querystring, parsed as object.
 *    - `parse_failed` (Boolean): Whether the parsing failed or not.
