Sergey Biryukov 89e665383f KSES: Display a notice if any of the required globals are not set.
When using the `CUSTOM_TAGS` constant, these global variables should be set to arrays:

* `$allowedposttags`
* `$allowedtags`
* `$allowedentitynames`
* `$allowedxmlentitynames`

This commit aims to improve developer experience by displaying a more helpful message to explain a PHP fatal error further in the code if any of these globals are either not set or not an array.

Note Using `CUSTOM_TAGS` is not recommended and should be considered deprecated. The `wp_kses_allowed_html` filter is more powerful and supplies context.

Sergey Biryukov 21eb7900b3 Docs: Clarify the `$allowed_protocols` default value in various KSES functions.
Add a note that the parameter is optional and defaults to the result of `wp_allowed_protocols()`.

This affects:
* `wp_kses()`
* `filter_block_content()`
* `filter_block_kses()`
* `filter_block_kses_value()`

Includes synchronizing the `$allowed_html` parameter description for consistency.

Sergey Biryukov 9ba0095255 KSES: Allow assigning values to CSS variables.
The `safecss_filter_attr()` function allows using custom CSS variables like `color: var(--color)`. However, it did not allow assigning values to CSS variables like `--color: #F00`, which is common in Global Styles and Gutenberg.

This commit adds support for assigning values to CSS variables, so that the function can be used consistently in Global Styles and the future Style Engine in Gutenberg.

`<ruby>` element and its friends are used to attach annotation text onto a piece of text. This is especially commonly used in Japanese content, but it can also been seen in content of other languages like Chinese.

The set of elements to enable such functionality consists of `<ruby>`, `<rt>`, and `<rp>` in the [https://html.spec.whatwg.org/multipage/text-level-semantics.html#the-ruby-element HTML Standard], while some browsers (like Firefox) additionally support `<rb>` and `<rtc>` for more advanced formatting, which are not yet included in the official HTML spec, but can be found in a [https://www.w3.org/TR/html-ruby-extensions/ W3C extension].

Gary Pendergast 2c3205bb84 KSES: Add options for restricting tags based upon their attributes.
This change adds two now attribute-related config options to KSES:
- An array of allowed values can be defined for attributes. If the attribute value doesn't fall into the list, the attribute will be removed from the tag.
- Attributes can be marked as required. If a required attribute is not present, KSES will remove all attributes from the tag. As KSES doesn't match opening and closing tags, it's not possible to safely remove the tag itself, the safest fallback is to strip all attributes from the tag, instead.

Included with this change is an implementation of these options, allowing the `<object>` tag to be stored in posts, but only when it has a `type` attribute set to `application/pdf`.

desrosj 4b60af1a6a General: Remove “whitelist” and “blacklist” in favor of more clear and inclusive language.
“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.

Adam Silverstein 810e9c3c2b Formatting: new filter `safecss_filter_attr_allow_css` on css parts.
Enables developers to determine whether a section of CSS should be allowed or discarded. By default, the value will be false if the part contains \ ( & } = or comments. Returning true allows the CSS part to be included in the output.

Replaces the `safe_style_disallowed_chars` filter introduced in r47891.

Props azaozz.

Pascal Birchler 609dd1d14f Sitemaps: Add XML sitemaps functionality to WordPress.
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()`.
