<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>General: Restore (un-deprecate) the `sanitize_url()` function.
A general security rule is "Sanitize when you save, escape when you echo", and for the most part WordPress has well-named functions like `sanitize_email()` and others, with `esc_url_raw()` being a single exception that does not follow the naming.
This commit restores the previously deprecated `sanitize_url()` function as a valid alias of `esc_url_raw()`.
This better aligns with the naming with other `sanitize_*()` functions:
* `sanitize_bookmark()`
* `sanitize_bookmark_field()`
* `sanitize_category()`
* `sanitize_category_field()`
* `sanitize_comment_cookies()`
* `sanitize_email()`
* `sanitize_file_name()`
* `sanitize_hex_color()`
* `sanitize_hex_color_no_hash()`
* `sanitize_html_class()`
* `sanitize_key()`
* `sanitize_meta()`
* `sanitize_mime_type()`
* `sanitize_option()`
* `sanitize_post()`
* `sanitize_post_field()`
* `sanitize_sql_orderby()`
* `sanitize_term()`
* `sanitize_term_field()`
* `sanitize_text_field()`
* `sanitize_textarea_field()`
* `sanitize_title()`
* `sanitize_title_for_query()`
* `sanitize_title_with_dashes()`
* `sanitize_trackback_urls()`
* `sanitize_user()`
* `sanitize_user_field()`
