wp_new_comment() WP 1.0

Adds a new comment to the database.

Filters new comment to ensure that the fields are sanitized and valid before inserting comment into database. Calls 'comment_post' action with comment ID and whether comment is approved by WordPress. Also has 'preprocess_comment' filter for processing the comment data before the function handles it.

We use REMOTE_ADDR here directly. If you are behind a proxy, you should ensure that it is properly set, such as in wp-config.php, for your environment.

See https://core.trac.wordpress.org/ticket/9235
