This change allows for external clients to supply a suggested filename via a `Content-Disposition` response header. This filename is processed through `sanitize_file_name()` to ensure it is allowable (on the server, MIME's, etc...) and `validate_file()` to prevent directory traversal.
If the suggested filename fails the above processing/checks, that suggestion is discarded and the standard temporary filename (generated by WordPress) is used.
If no `Content-Disposition` header is found in the response headers, the standard temporary filename continues to be used as per normal.
Included in this change are 6 additional PHPUnit tests with 9 assertions. These tests confirm that valid filename values are correctly saved, and invalid filename values are correctly rejected.

This replaces the `copy_dir()` usage in `WP_Upgrader::install_package()` and aims to avoid PHP timeout issues when installing or updating large plugins on slower systems like Vagrant or the WP Docker test environment.
The new function attempts a native PHP `rename()` function first and falls back to the previous `copy_dir()`.

As per the PHP manual:
> If the `component` parameter is omitted, an associative array is returned.
> If the `component` parameter is specified, `parse_url()` returns a string (or an int, in the case of `PHP_URL_PORT`) instead of an array. If the requested component doesn't exist within the given URL, `null` will be returned.
Reference: [https://www.php.net/manual/en/function.parse-url.php#refsect1-function.parse-url-returnvalues PHP Manual: parse_url(): Return Values]
This commit adds three unit tests for `download_url()`:
* The first test is "girl-scouting" to make sure that the code up to the point where the error is expected is tested.
* The second test exposed a PHP 8.1 `basename(): Passing null to parameter #1 ($path) of type string is deprecated` error due to the call to `parse_url()` returning `null` when the component requested does not exist in the passed URL.
* The output of the call to `parse_url()` stored in the `$url_path` variable is used in more places in the function logic. The third test exposes a second PHP 8.1 deprecation notice, this time for `substr(): Passing null to parameter #1 ($string) of type string is deprecated`.
This commit also removes duplicate `parse_url()` calls. Neither `$url` nor `$url_filename` are changed between when they are first received/defined and when they are re-used, so there is no need to repeat the function calls.

Instead of one cache entry for all upload folders for a site on multisite, this now caches for each folder and invalidates that cache based on context. In multisite, this should speed up `get_dirsize` calls since older directories that are much less likely to change will no longer have the size recalculated.

Using the canonical function name for PHP functions is strongly recommended, as aliases may be deprecated or removed without (much) warning.
This replaces all uses of the following:
* `join()` with `implode()`
* `sizeof()` with `count()`
* `is_writeable()` with `is_writable()`
* `doubleval()` with a `(float)` cast

When files are copied into place, check whether opcode invalidation is available and attempt to invalidate to avoid unintended behavior or fatal errors from themes, plugins, or core.
Introduces `wp_opcache_invalidate()` to allow safe invalidation of PHP files from opcode cache, and a filter, `wp_opcache_invalidate_file` to override the behavior.
Replaces the existing calls to `opcache_invalidate()` in the plugin and theme editors to use the new function.

For a number of years, most of the WordPress error messages have been prefixed with "Error:". However, these messages appear in a context where it's already clear an error occurred. Whether it's an error, a warning, or any other classification, that's not so relevant for users. The content of the message is the relevant part. The "Error:" prefix doesn't add great value while it does add unnecessary complexity for the message readability.
Also, revises some of these messages to improve clarity and removes HTML from translatable strings.

This change introduces a new Composer script, `compat` that will scan the codebase for (detectable) potential PHP compatibility issues using the `PHP_CodeSniffer` and a custom ruleset based off of the `PHPCompayibilityWP` ruleset (`phpcompat.xml.dist`).
The command will be run as a separate job within each Travis build. While many compatibility issues and false positives have already been corrected in this commit and other Trac tickets, there are still some remaining. For that reason, the job is allowed to fail while the remainder of the potential compatibility issues are investigated and addressed. After those are resolved, the job should be set as required to pass to help prevent new compatibility issues from being introduced.

* 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!

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.

This fixes several bugs in the signature verification code:
Disables signature checks on certain incompatible PHP versions that cause math errors when opcache is enabled;
Prevents a spurious URL and subsequent error when downloading a zip file with query arguments;
Prevents errors triggered by third-party upgrade scripts as per #46615;
Disables signature tests for Plugins, Themes, and Translations, leaving only core updates.
At the 5.2 release the API servers will only provide signatures for core update packages, which is why messages are suppressed for plugins and other package types. Signatures for those other items will become available later.

Previously, only `a` and `br` tags were allowed in the `value` table cell for each field included in the HTML file generated when a user is exporting their personal data. Instead of relying on a hardcoded list of allowed tags, the `wp_kses()` call in `wp_privacy_generate_personal_data_export_group_html()` will now fallback to the default list of allowed tags (which includes `i`, `strong`, `em`, and other basic HTML formatting tags).
Also, a new context of `personal_data_export` will now be passed to the `wp_kses()` call. As a result, the list of HTML tags and attributes allowed in the export file can now be filtered using the `wp_kses_allowed_html` filter and checking for the `personal_data_export` context.

In order to get the best result when running `phpcbf` across the codebase, there are some manual tweaks we need to make.
These fall into three categories:
- Fixing incorrectly indented code which has flow-on effects when auto-fixing.
- Tweaking the layout of inline PHP inside HTML tags.
- Moving more complex inline PHP inside HTML tags, to execute earlier.

Previously, personal data exports were stored in `wp-content/uploads/exports`, which is generic enough that it's likely there are existing folders with that name, either created by plugins or manually by administrators. If that folder were reused by Core, then `wp_privacy_delete_old_export_files()` would delete all of the existing files inside it, which is almost certainly not what the site owner wants or expects.
To avoid that, the folder is being renamed to include a specific reference to Core, and a more verbose description of its purpose. With those factored in, it's very unlikely that there will be any conflicts with existing folders.
The `wp_privacy_exports_dir()` and `wp_privacy_exports_url()` functions were introduced to provide a canonical source for the location, and the `wp_privacy_exports_dir` and `wp_privacy_exports_url` filters were introduced to allow plugins to customize it.

Whenever an admin initiates a download or email of a personal data export, a fresh copy of the file is generated. Previously, a new filename was used each time, which could lead to situations where a URL that was emailed to a data subject is broken.
