Per the [https://make.wordpress.org/core/handbook/best-practices/spelling/ spelling] and [https://make.wordpress.org/docs/style-guide/language-grammar/word-choice/ word choice] documentation guidelines, American (US) spelling should be preferred.

1d0e1397fd Code Modernization: Fix parameter name mismatches for parent/child classes in WP_Image_Editor::save().
Renames the first parameter in `WP_Image_Editor_GD::save()` to match the parent's method signature.
Why? PHP 8 introduces the ability to pass named arguments to function/method calls. This means the child and parent method signatures (i.e. parameter names) need to match.

Adds @since to clearly specify why the change happened.

Adds parameter descriptions to parent and both child classes. 

Follow-up to [22094], [22619], [30681].

a8d8f22f4e Media: Support Stream Wrappers In WP_Image_Editor_Imagick
Since `WP_Image_Editor`'s introduction, stream wrappers have functioned in `WP_Image_Editor_GD`, but haven't been properly supported in `WP_Image_Editor_Imagick`.

- Detects stream wrappers and uses `file_put_contents()` along with `Imagick::read/getImageBlob()` for handling when necessary.
- Introduces private method, `WP_Image_Editor_Imagick::write_image` to handle detection and proper saving.
- Introduces `WP_Test_Stream` class for testing stream wrappers, along with new tests for Imagick's stream handling and a stream filename test.

Adds requirement for `Imagick::readImageBlob()`, available in Imagick >= 2.0.0, which aligns with the current requirement of Imagick >= 2.2.0.

9cdd649768 Media: Work around use-cropbox bug in Ghostscript 8.70
Wraps `Imagick::readImage()` for PDFs with exception handling, trying again without `use-cropbox` if this fails.

Introduces `WP_Image_Editor_Imagick::pdf_load_source()`.

Works around a known issue in Ghostscript 8.70 (fixed in 8.71) that results in a stack underflow.
While it only affects this version, it remains a common version found on hosts, and prevented some PDF thumbnails from being generated.

4b60af1a6a General: Remove “whitelist” and “blacklist” in favor of more clear and inclusive language.
“The WordPress open source community cares about diversity. We strive to maintain a welcoming environment where everyone can feel included.”

With this commit, all occurrences of “whitelist” and “blacklist” (with the single exception of the `$new_whitelist_options` global variable) are removed. A new ticket has been opened to explore renaming the `$new_whitelist_options` variable (#50434).

Changing to more specific names or rewording sentences containing these terms not only makes the code more inclusive, but also helps provide clarity. These terms are often ambiguous. What is being blocked or allowed is not always immediately clear. This can make it more difficult for non-native English speakers to read through the codebase.

Words matter. If one contributor feels more welcome because these terms are removed, this was worth the effort.

abcbee954f Coding Standards: Fix instances of WordPress.PHP.NoSilencedErrors.Discouraged.
Noteable changes:
- The `magic_quotes_runtime` and `magic_quotes_sybase` settings were removed in PHP 5.4, so no longer need to be set.
- Some functions that use external libraries can generate errors that can't be tested for, so are globally allowed to silence errors.
- Quite a few functions would cause errors if `safe_mode` was set. This setting was removed in PHP 5.4.
- Only a handful of `header()` calls needed corresponding `headers_sent()` checks for unit tests to pass, but more may need to be added as the nightlies builds are tested.

05302bd054 Save progress of intermediate image creation after upload. First run.
- Introduces `wp_get_missing_image_subsizes()` and `wp_update_image_subsizes()` to generate image sub-sizes that are missing or were not created after the upload.
- Adds a way to display errors that happened while creating sub-sizes.
- Introduces `wp_create_image_subsizes()` intended for use after an image was uploaded. It saves/updates the image metadata immediately after each sub-size is created. This fixes the (long standing) problem when some of the sub-size image files were created but there was a timeout or an error and the metadata was not saved. Until now such uploads were considered "failed" which usually resulted in the user trying to upload the same image again, creating even more "orphan" image files.

Note that the patch also includes some unrelated WPCS fixes.

0860bb2771 Docs: Remove @access notations from method DocBlocks in wp-includes/* classes.
Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

454acad22e Media: Reset Exif orientation after rotate in WP_Image_Editor_Imagick.
Due to inconsistencies in the way browsers handle Exif orientation data,
if a user manually rotates an image within WordPress, set the Exif orientation to
the default (1) so that the image displays with the same rotation/flip in every browser.

e12d3813f0 Media: Allow override of PDF setup for multiple pages or DPI.
After [39187], WordPress started loading only the first page of a PDF.

This is appropriate for performance, but made it impossible to
write plugins that read other pages without overriding `load()`.

Introduces `WP_Image_Editor_Imagick->pdf_setup()`, to allow an override
to change WordPress' rendering DPI defaults or which pages are loaded.

Fixes #38832. See #38522, #31050.

a8e304ec8e Media: Add support for rendering PDF thumbnails.
When support for PDFs is available, on upload,
render 'Thumbnail', 'Medium', 'Large', and 'Full' sizes of
the first page, and save them in attachment meta.

Use these renders within Add Media, Media Gallery and List views,
Attachment Details, Post/Attachment Edit screens, and Attachment pages.

Support available by default via Imagick -> ImageMagick -> Ghostscript,
but can be provided by any `WP_Image_Editor` that supports PDFs.

aa561e67a1 Bootstrap: Enhance core's memory limit handling.
* 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.
