55cd633c37 Customize: Add additional filters to Customizer to prevent JSON corruption.
This solution extends the wp_insert_post_data filter to pass in addition to the slashed/sanitized/processed data, and the slashed/sanitized/unprocessed data, to also pass the initial slashed/unsanitized/unprocessed data which was passed into wp_insert_post(). This then allows plugins to have complete control over how sanitization is performed based on the post type.

47ed56f38f Code Modernization: Replace dirname( __FILE__ ) calls with __DIR__ magic constant.
This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.

This commit also includes:

* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
 * `wp-admin/admin-header.php`
 * `wp-admin/admin-footer.php`
 * `wp-includes/version.php`

583e49d95f Customize: Formally deprecate unused Customizer classes.
The `WP_Customize_New_Menu_Control` and `WP_Customize_New_Menu_Section` PHP classes and `wp.customize.Menus.NewMenuControl` JS class were deprecated in 4.9 through [42034] with the intention of removing them in 5.0. Since more time has passed than originally intended, this change leaves `WP_Customize_New_Menu_Control` and `WP_Customize_New_Menu_Section` to prevent any potential backwards compatibility issues, and formally deprecates them. The `wp.customize.Menus.NewMenuControl` JS class is removed.

3cf6276ed0 Code Modernization: Remove JSON extension workarounds for PHP < 5.6.
The PHP native JSON extension has been bundled and compiled with PHP by default since version 5.2.0. Because the minimum version of PHP required by WordPress is now 5.6.20 (see #46594 and [45058]), JSON extension related polyfills and backwards compatibility code can now be removed.

This change removes code that supported JSON related functionality on older versions of PHP. This includes (but is not limited to) checks that `json_last_error()` exists, checking and setting the `JSON_UNESCAPED_SLASHES` and `JSON_PRETTY_PRINT` constants if not previously defined, and deprecating the `_wp_json_prepare_data()` function (which was 100% workaround code).

16b8d91baa I18N: Improve translator comments.
* Add missing translator comments.
* Fix placement of some translator comments. Translator comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools. The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translator comments.

Includes minor code layout fixes.

Polyglots, rejoice! All WordPress core files now have translator comments for all strings with placeholders!

71cf332e65 Replace usages of basename() with wp_basename() in order to support multibyte filenames
This is focused on the pieces of code that touch media files and the tests that support them. `basename` isn't multibyte compatible out of the box. See http://php.net/basename and https://bugs.php.net/bug.php?id=62119.

See #43170.

d9a1f99d9c Customize: Remove wp_targeted_link_rel pre-save filter from change-sets.
The pre-save filters added to links in [43732] could invalidate JSON data when saving Customizer change-sets.

This removes the filters when saving and publishing change-sets.

d8f4a04232 Customizer: Improve browser compatibility of the preview iframe.
When `home` and `siteurl` are different, the customizer preview iframe will be blank in Chrome and Safari, due to their `X-Frame-Options` implementation quirks.

Changing this to `SAMEORIGIN` and adding the `frame-ancestors` Content Security Policy gives the correct behaviour.

Props fullyint.

1422d8ffd9 Customize: Safeguard a check on the customize_validate_{$setting_id} filter value to ensure it is a WP_Error.
While the filter is documented to only support a `WP_Error`, it has been a common practice to return true in a validation function if no errors have occurred. This was already caught when the same filter was executed in `WP_Customize_Setting`, it was however missing in `WP_Customize_Manager::validate_setting_values()`.

Fixes #44809.
