whyisjake 7448ce4839 Formatting: Prevent wp_slash from returning non-strings as strings.
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.

Fixes #42195, #24106.

whyisjake 919729508c Formatting: Improve the docblock for `sanitize_title()`.
Since sanitize title is largely used for html attributes, or post slugs, make note that accents will be removed and that the string will be limited to alphanumeric characters, underscores, and dashes.

Fixes #33756.

Sergey Biryukov 40c389c95e Docs: Standardize on "Returning a value from the filter" vs. "Passing a value to the filter".
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.

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()`.

Sergey Biryukov 6a039a5731 Code Modernisation: Introduce the spread operator in `wp-includes/formatting.php`.
Rather than relying `func_get_args()` to retrieve arbitrary function arguments, we can now use the spread operator to assign them directly to a variable.

Props jrf.

Aaron Jorbin dd3ad3ac51 GENERAL: Remove magic quote functions
The path to magic quote sanity took a fun and exciting turn: PHP core removed it and WordPress updated the minimum version.

For the formally external pclzip, the code is commented out to make investigating easier and in case we ever need to merge upstream (if that still exists) changes.

Props ayeshrajans, jrf, jorbin.
See #47783.
Fixes #18322.
