b0038c85f1 Sitemaps: Prevent incorrect redirection of paged sitemap requests.
Update `redirect_canonical()` to account for custom pagination and URL format used by sitemaps in order to follow standard practices.

Introduce the function `get_sitemap_url()` to simplify getting the index and provider URLs as needed.

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.

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()`.

5b046976cc Canonical: Redirect paged requests for a static page assigned as the "Posts page".
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.

d858656023 Bootstrap/Load: Make handling the /favicon.ico requests more flexible.
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()`.

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.

0ddbc2c99f Improve category check in redirect_canonical() when permastruct contains category slug.
[37262] changed a check in `redirect_canonical()` so that it checked
categories in the object cache rather than querying the database. However,
the check was based on the identity of `WP_Term` objects, which in
certain cases can be augmented by the main WP query routine, causing
failures of the `in_array()` check. This caused unnecessary redirects
for URLs where `is_single()` is true, but the URL is different from the
post permalink, such as the `embed` endpoint.

`has_term()` also checks the cache, but does not sufer from this bug.

a027edc277 Comments: The year is 2003. Permalinks are a new thing and everyone's using Blogger. It's a time when opening a modal window in JavaScript to view a section of a website is not a completely weird thing, although many users get annoyed by it. b2 has recently become WordPress, and with it comes a bunch of functionality that will become stale over the next decade, remnants of simpler times.
Twelve years later, after no fewer than three themes have intentionally implemented popup comments in their functionality, before being abandoned for at least the last six years, we've reached a time where we can put this era behind us. A time when we can remove comment popup functionality from WordPress.

If this breaks the internet, I'll eat my hat.

3eab09a694 Don't force comment pagination.
[34561] instituted the policy of forcing pagination for comments. This strategy
was intended to avert problems when 'page_comments' is set to 0 - as it is by
default - and the number of comments on a given post rises into the hundreds or
thousands. By forcing pagination in all cases, we ensured that WordPress would
not time out by processing unwieldy numbers of comments on a given pageload.

The strategy proves problematic, however, because comment permalinks are
generated using the page of the comment. Forcing pagination for posts that
were not previously paginated would change the URL of all comments that do not
appear on the default comment page.

This changeset reintroduces the 'page_comments' setting and its corresponding
checkbox on Settings > Discussion. A number of tests, which were written after
[34561], are modified to work now that 'page_comments' will, once again, be
disabled by default.

18d6b3c8dc Force comment pagination on single posts.
Previously, the 'page_comments' toggle allowed users to disable comment
pagination. This toggle was only superficial, however. Even with
'page_comments' turned on, `comments_template()` loaded all of a post's
comments into memory, and passed them to `wp_list_comments()` and
`Walker_Comment`, the latter of which produced markup for only the
current page of comments. In other words, it was possible to enable
'page_comments', thereby showing only a subset of a post's comments on a given
page, but all comments continued to be loaded in the background. This technique
scaled poorly. Posts with hundreds or thousands of comments would load slowly,
or not at all, even when the 'comments_per_page' setting was set to a
reasonable number.

Recent changesets have addressed this problem through more efficient tree-
walking, better descendant caching, and more selective queries for top-level
post comments. The current changeset completes the project by addressing the
root issue: that loading a post causes all of its comments to be loaded too.

Here's the breakdown:

* Comment pagination is now forced. Setting 'page_comments' to false leads to evil things when you have many comments. If you want to avoid pagination, set 'comments_per_page' to something high.
* The 'page_comments' setting has been expunged from options-discussion.php, and from places in the codebase where it was referenced. For plugins relying on 'page_comments', we now force the value to `true` with a `pre_option` filter.
* `comments_template()` now queries for an appropriately small number of comments. Usually, this means the `comments_per_page` value.
* To preserve the current (odd) behavior for comment pagination links, some unholy hacks have been inserted into `comments_template()`. The ugliness is insulated in this function for backward compatibility and to minimize collateral damage. A side-effect is that, for certain settings of 'default_comments_page', up to 2x the value of `comments_per_page` might be fetched at a time.
* In support of these changes, a `$format` parameter has been added to `WP_Comment::get_children()`. This param allows you to request a flattened array of comment children, suitable for feeding into `Walker_Comment`.
* `WP_Query` loops are now informed about total available comment counts and comment pages by the `WP_Comment_Query` (`found_comments`, `max_num_pages`), instead of by `Walker_Comment`.

Aside from radical performance improvements in the case of a post with many
comments, this changeset fixes a bug that caused the first page of comments to
be partial (`found_comments` % `comments_per_page`), rather than the last, as
you'd expect.
