The trunk and this feature branch are now and synced.
For starters, [27050] is rad. This just cleans up some extra new lines that were littered about, updates *some* of the inline docs (needs more), moves `wp.media.controller.ImageDetails` closer to its parent class, and de-dupes some code in `media-template.php`.

See #24409.

Update the versions of several `devDependencies` in `package.json`. `grunt-cssjanus` has been updated to `0.2.2`, we no longer need the fork. Run `npm install` to receive updates for `node_modules` in the project root.

Props yoavf, TobiasBg.

In `wpdb::db_connect()`, allow the loading of a custom database error template - this is already allowed in `dead_db()`.

In `dead_db()`, move the call to `wp_load_translations_early()` before the inclusion of the `db-error.php` file to allow translation in both locations before the template is loaded.

Props sbruner, kovshenin.
Fixes #25703.

`get_comment()`, `wp_get_post_revision()`, and `get_term()` all used to return by reference. Because of this, `$null` was set to `null` so the return value would be a variable where applicable. This has not been necessary since [21792], so the `$null`s have been removed.

Props toszcze.
Fixes #24768.

Let the video shortcode accept a YouTube URL as the value of its `src` attribute, as MediaElement.js supports Chromeless YouTube videos by using a pseudo-mime-type `video/youtube`. 

HTTP and HTTPS www, non-www, and short url fronts are supported:
http://www.youtube.com/watch 
https://www.youtube.com/watch
http://youtube.com/watch
https://youtube.com/watch
http://youtu.be

Remove `$force` argument from `WP_Object_Cache::delete()`. From @nacin: "This was for internal-use-only, I don't think _deprecated_argument() is needed, but let's put a comment somewhere just so we know we'd have to be careful if we ever want to add a third argument here later."

`$force` argument has been removed, and docs were updated.

Fixes #22478.
