Sometimes, `DB_CHARSET` will be set to `utf8mb4`, even if the current setup doesn't support `utf8mb4`. After [38442], this can cause significant character set failures, causing the connection to fall back to `latin1`.
Instead of doing this, we now check that the connection supports `utf8mb4` before trying to use it, and fall back to `utf8` when we need to.
Fixes#37982 for trunk.

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.

The Customizer and Theme Installer open in full overlays that need to receive
focus. Also, keyboard navigation should be constrained within the overlays. Using
CSS `visibility` to hide all the content except the overlays, makes them the only
available and focusable content and allows browsers to handle focus natively.

Additionally, update the `$message` parameter description in the DocBlock for `wp_die()` to make it explicitly clear messages derived from a passed `WP_Error` object will only be evaluated if not performing an Ajax or XML-RPC request (as both default handlers completely ignore `WP_Error` object messages).

`wp_get_network()` was converted into a wrapper for `get_network()` in 4.6.0 and can now be deprecated.
This moves `wp_get_network()` to the bottom of `ms-load.php` as `ms-deprecated.php` is not available early enough.

* Eliminates the server mutating the a `WP_Error`'s `$error_data` to merge-in a `$from_server` flag (since it may not be an array to begin with). Instead it defers to the client to add a `fromServer` param on any `Notification` instances created from server-sent errors.
* Ensures that notifications will be re-rendered if a notification's `message` changes but the `data` and `type` remain the same.
* Adds explicit support for the `Notification` class to have a `setting` property, ensuring that the property is set whereas previously it was dropped.

After [38364], the inclusion of `class-wp-locale.php` was changed from a `require_once()` to a `require()`. This caused problems for anything that called `load_text_domain_early()` prior to the `require()` but didn't bail, as it was now being `require()`-ed a second time.
With the use of `require_once()`, it doesn't really matter where it's loaded, so it has been moved next to the related `l10n.php` load.
