Ensure logged out users are redirected to the media file when attachment pages are inactive. This removes the read_post capability check from the canonical redirects as anonymous users lack the permission.
This was previously committed in [57310] before being reverted in [57318]. This update includes a fix to cover instances where revealing a URL could be considered a data leak and greatly expands the unit tests to ensure that this is covered along with many other instances.

WordPress creates attachment pages by default for every attachment uploaded. On the vast majority of sites, these attachment pages don't contain any meaningful information. They do however exist, get indexed by search engines, and sometimes even rank in search results, leading to bad results for users and site owners.
This commit introduces a `wp_attachment_pages_enabled` database option to control the attachment pages behavior:
* On existing sites, the option is set to `1` on upgrade, so that attachment pages continue to work as is.
* For new sites, the option is set to to `0` by default, which means attachment pages are redirected to the attachment URL.
* Sites that want to enable or disable the attachment pages can set the option to `1` or `0`, respectively.

WordPress core includes a polyfill for `str_contains()` on PHP < 8.0 as of WordPress 5.9.

Add check to `redirect_canonical()` to ensure private posts only redirect for logged in users.
Modifies the `read_post` mata capability to user `get_post_status()` rather than the post's `post_status` property to allow attachments to redirect based on the inherited post status.
Introduces `wp_force_ugly_post_permalink()` to unify the check to determine if an ugly link should be displayed in each of the functions used for determining permalinks: `get_permalink()`, `get_post_permalink()`, `_get_page_link()` and `get_attachment_link()`.
Improves logic of `get_attachment_link()` to validate parent post and resolution of inherited post status. This is an incomplete fix of #52373 to prevent the function returning links resulting in a file not found error. Required to unblock this ticket.

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()`.

This avoids displaying duplicate content of the home page under different URLs with appended page numbers.
This change only affects the `<!--nextpage-->` pagination (`page` query variable) and not the regular multiple posts pagination (`paged` query variable).
The posts page does not support the `<!--nextpage-->` pagination, so requests for invalid page numbers should be redirected to the page permalink, applying the logic previously implemented for single posts or pages.

Previously, `wp_favicon_request()` was introduced in [13205] to avoid a performance hit of serving a full 404 page on every favicon request.
While working as intended, that implementation did not provide a way for theme or plugin authors to manage the behavior of favicon requests.
This changeset implements the following logic (only applied if WordPress is installed in the root directory):
* If there is a Site Icon set in Customizer, redirect `/favicon.ico` requests to that icon.
* Otherwise, use the WordPress logo as a default icon.
* If a physical `/favicon.ico` file exists, do nothing, let the server handle the request.
Handling `/favicon.ico` is now more consistent with handling `/robots.txt` requests.
New functions and hooks:
* Introduce `is_favicon()` conditional tag to complement `is_robots()`.
* Introduce `do_favicon` action to complement `do_robots` and use it in template loader.
* Introduce `do_favicon()` function, hooked to the above action by default, to complement `do_robots()`.
* Introduce `do_faviconico` action to complement `do_robotstxt`, for plugins to override the default behavior.
* Mark `wp_favicon_request()` as deprecated in favor of `do_favicon()`.
