Message:

Move deprecated functions to deprecated.php. Deprecate get_the_attachment_link() for wp_get_attachment_link(), get_attachment_icon_src() for wp_get_attachment_image_src(),
get_attachment_icon() and get_attachment_innerHTML() for wp_get_attachment_image(), get_link() for get_bookmark(). Add missing deprecated version numbers. Add inline documentation to pluggable functions that are deprecated. See #11388
