7c60a660f1 Code Modernization: Correct the check for negative post IDs in WP_Query::parse_query() to work as expected on PHP 8.
PHP 8 changes the way string to number comparisons are performed: https://wiki.php.net/rfc/string_to_number_comparison

In particular, checking if an empty string is less than zero in PHP 8 evaluates to `true`, not `false`.

For `WP_Query`, this resulted in unintentionally returning a 404 error for most of front-end requests, instead of the relevant content.

By explicitly casting the value to `int`, we make sure to compare both values as numbers, rather than a string and a number.

Follow-up to [38288].

Props trepmal.

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()`.

05fa2363ab Posts: Avoid the use of globals in get_the_content() and related functions.
This changeset introduces `$post` parameters to `get_the_content()` and
`wp_trim_excerpt()`. When a `$post` object is passed to one of these functions,
the functions will operate on the data from that object, rather than from the
post globals (`$authordata`, `$page`, etc). This ensures that the functions work
in a predictable manner when used outside of the regular post loop.

The global-mismatch problem is surfaced in cases where `get_the_excerpt()` is
called outside of the post loop, on posts that don't have a defined excerpt. In
these cases, the post globals - used to generate a fallback excerpt - may refer
to the incorrect object, resulting in PHP notices or other unpredictable
behavior. See #36934 for a related issue.

Props spacedmonkey, kraftbj, Shital Patel.
Fixes #42814.

5950f27205 Query: Standardize treatment of 'orderby' values post__in, post_parent__in, and post_name__in.
Ordering by `post__in` was introduced in [21776], but the code assumed that
`post__in` would be a comma-separated string listing post IDs. When an array
of post IDs was passed to the `post__in` query var, 'orderby=post__in' was
not respected. This changeset changes this behavior by handling
'orderby=post__in' in the same way as most other values of 'orderby',
which ensures that arrays as well as strings can be properly parsed.

The same treatment is given to the similar `post_name__in` and
`post_parent__in` options of 'orderby', so that most query generation for
orderby clauses happens in the same place, instead of in special cases.

A slight change in the resulting SQL (related to the whitespace around
parentheses and commas) necessitates a change to an existing REST API test
that does a string comparison against the SQL query.
