Allow supports => false to be passed to register_post_type() to disable the default title and editor.

An empty array may also disable all default features in the future.
Do not rely on this behavior: always specify title and editor if you want them.

Fold Privacy Settings into Reading Settings, moving blog_public (search engine/robots) to options-reading and removing options-privacy.

When blog_public only has two values (as judged by whether the blog_privacy_selector action is used), convert from radio buttons to a checkbox, and rename from 'Site Visibility' to a more specific 'Search Engine Visibility'.

The text and implementation may change a bit. see #16416.
