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.

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()`.

Gary Pendergast 1947e4424a KSES: Allow `url()` to be used in inline CSS.
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.

Merges [43781] from the 5.0 branch to core.

Gary Pendergast 56c162fbc9 Coding Standards: Upgrade WPCS to 1.0.0
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.

Fixes #44600.
