[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.

After [34561], `wp_list_comments()` no longer passed all of a post's comments
to `Walker_Comments`. As a result, calls to `get_comment_link()` occurring
inside the comment loop had insufficient context to determine the proper
'cpage' value to use when generating comment permalinks. This, in turn, caused
comment permalinks to behave erratically.
The current changeset addresses the problem as follows:
* `get_comment_link()` now accepts a 'cpage' parameter. When present, 'cpage' will be used to build the comment permalink - no automatic calculation will take place.
* When called within the main loop, `wp_list_comments()` calculates the proper 'cpage' value for comments in the loop, and passes it down to `get_comment_link()`.
* `cpage` and `comment-page-x` query vars are generally required in comment permalinks (see #34068), but an exception is made when 'default_comment_page=oldest': the bare post permalink will always be the same as `cpage=1`, so `cpage` is excluded in this case.

[34561] "fixed" the problem of newest-first comments showing fewer than
'per_page' comments on the post permalink when the total number of comments
was not divisible by 'per_page'. See #29462. But this fix caused numerous
other problems. First, comment pages reported by `get_page_of_comment()`
(which expects comment pages to be filled oldest-first) were no longer correct.
Second, and more seriously, the new logic caused comments to be shifted
between pages, making their permalinks non-permanent.
The current changeset reverts the changed behavior. In order to preserve the
performance improvements introduced in [34561], an additional query must be
performed when 'default_comments_page=newest' and 'cpage=0' (ie, you're viewing
the post permalink). A nice side effect of this revert is that we no longer
need the hacks required to determine proper comment pagination, introduced in
[34561].

Lazy-loading logic is moved to a method on `WP_Query`. This makes it possible
for comment feeds to take advantage of metadata lazyloading, in addition to
comments loaded via `comments_template()`.
This new technique parallels the termmeta lazyloading technique introduced in

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.

[34268] introduced cache priming for commentmeta, enabled by default. To
ensure performance on single post pages - where commentmeta is most likely
to cause performance issues - we disable up-front cache-priming. Instead, we
prime commentmeta caches for all comments in the loop the first time
`get_comment_meta()` is called on the page.

Screen Reader text improves the user experience for screen reader users. It provides additional context for links, document forms and other pieces of a page that may exist visually, but are lost when looking only at the html of a site. This does change the output of comments_popup_link if you don't pass in values for $zero, $one, $more or $none. Theme authors can and should style <code>.screen-reader-text</code> in ways that are recommended in the above article to hide it visually.

`comments_template()` is used by most themes to display a post's comments. It
shows all comments that have been approved, and also shows all pending comments
by the current visitor (as determined by the comment cookies). However, the
comments API previously had no way of querying for "all comments that are
either approved, or are unapproved but written by foo@example.com". The
workaround was a direct SQL query: uncached, not subject to the same filters as
other comment queries, and just generally icky.
The new `include_unapproved` parameter for `WP_Comment_Query` accepts an array
of user IDs or email addresses. Pending comments associated with users in this
array will be included in query results, regardless of the value of the 'status'
parameter. In `comments_template()`, we leap from direct SQL queries to
`get_comments()` plus `include_unapproved', striving to put right what once
went wrong.
