First added in [37588] and later modified in [38224], the idea was to ensure that filters/actions added before `advance-cache.php` would not disappear if `advance-cache.php` overloaded the filters/actions with code such as `$wp_filter = array()`. This is an edge case and one that there is no documented case of existing.
This restores the behavior from WordPress 4.5 and before. It is strongly encouraged that developers using `advance-cache.php` to use the Plugins API that is available before the loading of `advance-cache.php` rather than directly interacting with any of the globals.

[37588] added methods to backup the plugin globals, for ensuring that advanced cache drop-ins don't overwrite hooks that've been added earlier in the load process.
The method for restoring the plugin globals wasn't compatible with the implementation of `WP_Hook` in #17817. `WP_Hook` implements `ArrayAccess`, so `_restore_plugin_globals()` was treating it as an array, and inadvertantly overwriting the `WP_Hook` object with a plain array.
To avoid having to re-write this code as part of #17817, we now use `add_filter()` to restore any hooks that were added by cache drop-ins, which `WP_Hook` correctly supports.

[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.
Props cmillerdev.

Requests has its own cookie object in form of `Requests_Cookie`. Therefore we have to convert `WP_Http_Cookie` objects to `Requests_Cookie`.

* `preconnect` will be potentially pretty heavy on the CDN. With the Unicode 9.0 emoji update, almost all browsers will trigger the `preconnect`.
* `preconnect` only opens one connection, but `s.w.org` is HTTP/1.1, so the browser will use the preconnected connection for the first emoji, then it has to open new connections for subsequent emoji.
Also use the same URL as we use for the `emoji_svg_url` filter. This will print the hint for the correct CDN in case someone uses a custom CDN.

When `IMAGE_EDIT_OVERWRITE` is set to true, edited image files are
supposed to be deleted when an image is restored to the original.
However, when an image was edited more than once, and then restored,

Prior to the introduction of `WP_Term_Query`, the 'orderby' clause
passed to the 'terms_clauses' filter was prefixed by `ORDER BY`. After
`WP_Term_Query`, this was not the case; `ORDER BY` was added after the
filter. As such, plugins filtering 'terms_clauses' and returning an
'orderby' clause beginning with `ORDER BY` resulted in invalid syntax
when `WP_Term_Query` prepended a second `ORDER BY` keyword to
the clause.
This changeset rearranges the way the 'orderby' clause is built so that
it will be passed to 'terms_clauses' in the previous format.

Registration is now based solely on object type, which allows the code around this to be simplified significantly.
In the process of making this adjustment:
* `register_meta()`, `unregister_meta_key()`, `get_registered_metadata()`, and `registered_meta_key_exists()` no longer return `WP_Error` objects.
* The recently introduced `wp_object_type_exists()` function and the restriction on object type has been removed.
Note: No guarantee of uniqueness is made across object subtypes. Registered meta keys should be uniquely prefixed to avoid conflict.

When `$size` is passed to `image_get_intermediate_size()` as an array of width
and height values and an exact image size matching those values isn't available,
the function loops through the available attachment sizes and returns the
smallest image larger than the requested dimensions with the same aspect ratio.
The aspect ratio check is skipped for the 'thumbnail' size to provide a fallback
for small sizes when no other image option is available. This resulted in a poor
selection when the size requested was smaller than the 'thumbnail' dimensions
but a larger size matching the requested ratio existed.
This refactors the internals of `image_get_intermediate_size()` to ensure the
'thumbnail' size is only returned as a fallback to small sizes once all other
options have been considered, and makes the control flow easier to follow.
This also introduces a new helper function, `wp_image_matches_ratio()` for
testing whether the aspect ratios of two sets of dimensions match. This function
is also now used in `wp_calculate_image_srcset()` during the selection process.

Previously, `wp_mail()` implemented Reply-To as a generic header, using
PHPMailer's `addCustomHeader()`. As such, the email address portion of
the header was being incorrectly encoded when the name portion
contained UTF-8 characters. Switching to PHPMailer's more specific
`addReplyTo()` method fixes the issue.
For greater readability, the handling of all address-related headers
(To, CC, BCC, Reply-To) has been standardized.

When using `register_meta()` with the function signature from 4.5 and earlier, the `auth_{$type}_meta_{$key}` and `sanitize_{$type}_meta_{$key}` filters are used. Any calls to `register_meta()` expecting this behavior should continue to work. The new filters, which take advantage of object subtypes, should not be added unless the proper `$args` array is passed.

* Don't lower memory limit if the current limit is greater than `WP_MAX_MEMORY_LIMIT`.
* Set `WP_MEMORY_LIMIT` and `WP_MAX_MEMORY_LIMIT` to current limit if the `memory_limit` setting can't be changed at runtime.
* Use `wp_convert_hr_to_bytes()` when parsing the value of the `memory_limit` setting because it can be a shorthand or an integer value.
* Introduce `wp_raise_memory_limit( $context )` to raise the PHP memory limit for memory intensive processes. This DRYs up some logic and includes the existing `admin_memory_limit` and `image_memory_limit` filters. The function can also be used for custom contexts, the `{$context}_memory_limit` filter allows to customize the limit.
* Introduce `wp_is_ini_value_changeable( $setting )` to determine whether a PHP ini value is changeable at runtime.
* Remove a `function_exists( 'memory_get_usage' )` check. Since PHP 5.2.1 support for memory limit is always enabled.

When enabled, the switch would override the theme's pseudo-plural `'% Comments'` string with a correct form of `_n( '%s Comment', '%s Comments', $number )`.
Historically, `comments_popup_link()` and `get_comments_number_text()` did not support plural forms and used a pseudo-plural style instead, so some locales were forced to come up with workarounds to display the number of comments in their language correctly.
This change should make those functions more i18n-friendly.
