This addresses a regression in [47808], which caused excerpts to be generated from post content if an empty string is passed, but not for other values considered empty, e.g. `null` or `false`.

There are two pieces in here:
1) The update to change blacklist to blocklist is moved to disallowed_list. "Block" has a meaning in our code, and there could be ambiguity between this code and code related to blocks.
2) This improves backwards compatibility for code that was accessing the now deprecated code.

If a bool/float/int is passed into wp_slash it will be coerced into a string.
This changes the behavior to only slash strings. At the same time, handles recursion a little nicer by calling array_map for arrays.

The filter is the callback function added with `add_filter()`, therefore the hook passes a value to the filter, and the filter returns a value to change its behaviour.
The documentation is referring to the latter.

“The WordPress open source community cares about diversity. We strive to maintain a welcoming environment where everyone can feel included.”
With this commit, all occurrences of “whitelist” and “blacklist” (with the single exception of the `$new_whitelist_options` global variable) are removed. A new ticket has been opened to explore renaming the `$new_whitelist_options` variable (#50434).
Changing to more specific names or rewording sentences containing these terms not only makes the code more inclusive, but also helps provide clarity. These terms are often ambiguous. What is being blocked or allowed is not always immediately clear. This can make it more difficult for non-native English speakers to read through the codebase.
Words matter. If one contributor feels more welcome because these terms are removed, this was worth the effort.

While web crawlers are able to discover pages from links within the site and from other sites, XML sitemaps supplement this approach by allowing crawlers to quickly and comprehensively identify all URLs included in the sitemap and learn other signals about those URLs using the associated metadata.
See https://make.wordpress.org/core/2020/06/10/merge-announcement-extensible-core-sitemaps/ for more details.
This feature exposes the sitemap index via `/wp-sitemap.xml` and exposes a variety of new filters and hooks for developers to modify the behavior. Users can disable sitemaps completely by turning off search engine visibility in WordPress admin.
This change also introduces a new `esc_xml()` function to escape strings for output in XML, as well as XML support to `wp_kses_normalize_entities()`.

Introduce `make_clickable_rel` filter for the `rel` value that is added to URL matches converted to links.
This is a follow-up to [46349], which added the `rel="nofollow ugc"` attribute to existing `<a>` tags in comments via `wp_rel_ugc()`.
UGC stands for User Generated Content, and the `ugc` attribute value is recommended for links within user generated content, such as comments and forum posts.

When a theme declares HTML5 support for script and styles via `add_theme_support( 'html5', array( 'script', 'style' ) )`, the `type="text/javascript"` and `type="text/css"` attributes are omitted.
These attributes are unnecessary in HTML5 and cause warnings in the W3C Markup Validation Service.
