 *
 * - user_cancel_block = disable the account, but keep contents.
 * - user_cancel_block_unpublish = disable the account and unpublish contents.
 * - user_cancel_reassign = delete account but move content to anonymous
 *
 * For 'user_cancel_block', this hook does nothing.
 *
 * For 'user_cancel_block_unpublish', this hook clears the sharing grants
 * for all folders owned by the user.
 *
 * For 'user_cancel_reassign', this hook changes the ownership of all
 * of the user's folders to be anonymous.  The user is also removed from
 * shared access to any other content.
 *
 * Modules may add cancelation methods, but this hook ignores them.
