/**
 * This function is responsible for generating a comment reply form.
 * There are several cases that have to be handled, including:
 *   - replies to comments
 *   - replies to nodes
 *   - attempts to reply to nodes that can no longer accept comments
 *   - respecting access permissions ('access comments', 'post comments', etc.)
 *
 * The node or comment that is being replied to must appear above the comment
 * form to provide the user context while authoring the comment.
 *
 * @param $node
 *   Every comment belongs to a node. This is that node.
 *
 * @param $pid
 *   Some comments are replies to other comments. In those cases, $pid is the parent
 *   comment's cid.
 *
 * @return array
 *   An associative array containing:
 *   - An array for rendering the node or parent comment.
 *     - comment_node: If the comment is a reply to the node.
 *     - comment_parent: If the comment is a reply to another comment.
 *   - comment_form: The comment form as a renderable array.
