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.

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()`.

`wp_kses_bad_protocol()` makes sure to validate that uri attributes don’t contain invalid/or not allowed protocols. While this works fine in most cases, there’s a risk that by using the colon html5 named entity, one is able to bypass this function.

Adds support for `flex`, `grid` and `column` layout techniques to the list of CSS attributes considered safe for inline CSS. The `\` character and CSS functions, eg `minmax()` are not yet supported.
Extends support of `border` properties to include `border-radius` and individual `background` properties to include all those implicitly supported by the shorthand attribute.

This commit introduces the `wp_kses_uri_attributes` function and filter. The function centralizes the list of attributes, in order to prevent inconsistency, and the filter provides a way for plugins to customize the attributes.

The cover image block uses the `url()` function in its inline CSS, to show the cover image. KSES didn't allow this, causing the block to not save correctly for Author and Contributor users. As KSES does already check each attribute name against an allowed list, we're able to add an extra check for certain attributes to be able to use the `url()` function, too.

WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.
This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script.
- Auto-fixable coding standards issues will now cause Travis failures.

We have a handful of super long regexen that are written over multiple lines, as a collection of strings concatenated together. Each string is indented appropriately for the regex, but PHPCS doesn't recognised this, so defaults to removing the extra whitespace.
Disabling the `Squiz.Strings.ConcatenationSpacing.PaddingFound` rule for these blocks stops the extra whitespace from being removed.

The WPCS `WordPress.WhiteSpace.PrecisionAlignment` rule throws warnings for a bunch of code that will likely cause issues for `wpcbf`. Fixing these manually beforehand gives us better auto-fixed results later.

This function was originally introduced to fix an XSS attack in Netscape 4, which never affected any other browsers, or later versions of Netscape.
I'm willing to go out on a limb, and say that we've officially dropped security support for Netscape 4.

Known functions, classes, and methods are now auto-linked in Code Reference pages following #meta1483.
Note: Hook references are still linked via inline `@see` tags due to the unlikelihood of reliably matching for known hooks based on a RegEx pattern.
