Removes contents for sections and panels from being logically nested (in the DOM) in order to eliminate many issues related to using `margin-top` hacks. The element containing the link to expand the content element for panels and sections is now a sibling element to its content element: the content is removed from being nested at initialization. The content element is now available in a `contentContainer` property whereas the head element (containing the link to open the construct) is in a `headContainer` property. The existing `container` property is now a jQuery collection that contains both of these elements. Since the head element is no longer in an ancestor element to the `content` element, the `aria-owns` property is now used to maintain the relationship between the `headContainer` and the `contentContainer`. These changes are also accompanied by an improvement to the animation performance for the sliding panes.

Bulk action filtering was introduced in 3.1, but only to remove default bulk actions, not add new ones.
Bulk actions can now be registered for all admin list table dropdowns via the `bulk_actions-{get_current_screen()->id}` filter. Handling custom bulk actions can be performed in the corresponding and newly introduced `handle_bulk_actions-${get_current_screen()->id}` filter.

In rare circumstances, for example buttons with icons and no visible text,
`user-select: none;` may trigger a bug that happens only when using Safari and
VoiceOver and doesn't allow focusable elements to receive focus correctly.
Worth reminding `user-select: none;` is a non-standard property and should be
used with care especially now that `::selection` is almost universally supported.

If there are no pages when the customizer is opened, the `static_front_page` section will be hidden. As soon as a page is created in the customizer session, the `static_front_page` section will be revealed. Previously the section would not be registered if there were no pages. Page stubs created via nav menus will appear in the `dropdown-pages` controls for `page_for_posts` and `page_on_front`, and such page stubs will thus cause the `static_front_page` section to appear. Plugins that facilitate page creation in the customizer by filtering `get_pages` will also cause the section to appear.

Post Passwords are incredibly inflexible. One Password per site at a time and other limitations that can't really be changed without a backwards compatibility break. This adds the ability for sites to change the password behavior such as doing per post passwords or allowing multiple passwords to be set in a browser. The possibilities are YUGE.
Additionally, it allows for a behavior other than returning a html form when a password is needed. This is important for non website use cases (such as in a restful API).

[38592] changed the behaviour of `wpautop()` , so it's nice to change `autop()` to match.
Interestingly, this change isn't necessary for the functionality to work - #4857 didn't affect content that had been run through `autop()` at some point, as `autop()` would add a single line break before block elements, then `wpautop()` would later add a second line break, making it work correctly.

The most useful function this introduces is `get_theme_file_uri()`, which returns the URL to the specified file in the child theme if it exists, and falls back to the URL to the specified file in the parent theme. This allows parent themes to reference files (including enqueuing CSS and JavaScript files) that can be overridden by the child theme simply by existing.
This change also introduces `get_theme_file_path()`, which is the file path equivalent of `get_theme_file_uri()`.
Finally, `get_parent_theme_file_uri()` and `get_parent_theme_file_path()` are also introduced, which allow a theme to specifically reference a file URL or file path in the parent theme. These can be used as replacements for `get_template_directory_uri()` and `get_template_directory()` respectively, for consistency.

Filters and actions have been the basis of WordPress' plugin functionality since time immemorial, they've always been a reliable method for acting upon the current state of WordPress, and will continue to be so.
Over the years, however, edge cases have cropped up. Particularly when it comes to recursively executing hooks, or a hook adding and removing itself, the existing implementation struggled to keep up with more complex use cases.
And so, we introduce `WP_Hook`. By changing `$wp_filter` from an array of arrays, to an array of objects, we reduce the complexity of the hook handling code, as the processing code (see `::apply_filters()`) only needs to be aware of itself, rather than the state of all hooks. At the same time, we're able te handle more complex use cases, as the object can more easily keep track of its own state than an array ever could.

Adds an `item_spacing` option to the arguments array for the functions `wp_nav_menu()`, `wp_list_pages()`, and `wp_page_menu()`. `item_spacing` is a boolean accepting either `preserve` or `discard`.
Previously, certain CSS choices could result in a site's layout changing if `wp_nav_menu()` fell back to the default `wp_list_pages()` due to differences in the whitespace within the HTML. The new argument ensures a function outputs consistant HTML while maintaining backward compatibility.
