Revisions: optimize performance when post has large number of revisions.

Browse Source 
Improve speed and reduce the memory footprint when loading posts with many revisions.

* Use a direct query in `wp_get_post_autosave` to avoid loading all revisions.
* Query for IDs vs full objects in `register_and_do_post_meta_boxes`.
