The descendant query in `WP_Comment_Query::fill_descendants()` uses the clauses
of the main `get_comment_ids()` query as a basis, discarding the `parent`,
`parent__in`, and `parent__not_in` clauses. As implemented in WP 4.4 [34546],
the WHERE clause was assembled in such a way that any modifications applied
using the `comments_clauses` filter were not inherited by `fill_descendants()`.
This resulted in descendant queries that did not always properly filter
results, and sometimes contained syntax errors.
The current changeset fixes the problem by using the post-filter WHERE clause
as the basis for the `fill_descendants()` query. This change requires a new
approach for eliminating the unneeded parent-related clauses: instead of
eliminating values in an associative array, we must use regular expressions.

[36157] fixed a bug whereby `wp_list_comments()` would not properly recognize
custom pagination arguments. See #35175. However, it inadvertently introduced
a bug that caused any `$comments` array explicitly passed to the function to be
ignored, when that array was accompanied by pagination arguments that differ
from those in `$wp_query`. We address this bug by moving the logic introduced
in [36157] inside a block that only fires when no `$comments` array has been
provided to the function.

In order to calculate comment pagination when newest comments are displayed
first, `comments_template()` must perform a separate query to determine the
total number of paginating comments available on a post. See [34729], #8071,
pagination calculation - can be defined as a top-level comment, or a comment
with `parent=0`. However, when comment threading is disabled, yet comments
exist in the database that have parents, all comments - even those with a
parent - are "paginating". (This typically happens when comments threading was
once enabled, but has since been turned off.) As such, the total-paginating-
comments query should only be limited to top-level comments when
'thread_comments' is disabled.

Added hardcoded maxlength attributes on the author, author_email, author_url, and comment_field input markup. These can be modified via the comment_form_defaults filter. Added logic in wp_handle_comment_submission() to return a WP_Error when the comment_author, comment_author_url, or comment_content values exceed the max length of their columns. Introduces wp_get_comment_column_max_length() which returns the max column length for a given column name, and is filterable. Unit tests included for the error conditions in wp_handle_comment_submission()

`array_slice()` must be told to preserve keys when the query results exceed the

The introduction of negative search terms in 4.4 [34934] introduced the
possibility that the ORDER BY clause of a search query could be assembled in
such a way as to create invalid syntax. The current changeset fixes this by
ensuring that the ORDER BY clause corresponding to the search terms is
excluded when it would otherwise be empty.

When hierarchical=true, `WP_Comment_Query` will always fetch comments according
to the comment hierarchy, even if 'thread_comments' is disabled for the site.
This can cause problems when comment threading is disabled after threaded
comments have been recorded on the site; comments will no longer be returned in
a strictly chronological order.
We address the issue by refraining from querying hierarchically when comment
threading is disabled.
