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]
In this case, `parse_url()` is called with the `PHP_URL_PATH` as `$component`. This will return `null` in the majority of cases, as – exсept for subdirectory-based sites – `home_url()` returns a URL without the trailing slash, like `http://example.org`.
The return value of `parse_url()` was subsequently passed to `trim()`, leading to a `trim(): Passing null to parameter #1 ($string) of type string is deprecated` notice on PHP 8.1.
Fixed by adjusting the logic flow to:
* Only pass the return value of `parse_url()` to follow-on functions if it makes sense, i.e. if it isn't `null`, nor an empty string.
* Preventing calls to `preg_replace()` and `trim()` further down in the function logic flow, when `preg_replace()`/`trim()` would have nothing to do anyhow.

This fixes a "Deprecated: Automatic conversion of false to array is deprecated" warning on PHP 8.1.
In `wp_schedule_event()`, the cron info array is retrieved via a call to `_get_cron_array()`, but as the documentation (correctly) states, the return type of that function is `array|false`, where `false` is returned for a virgin site, with no cron jobs scheduled yet.
However, no type check is done on the return value, and the `wp_schedule_event()` function just blindly continues by assigning a value to a subkey of the `$crons` "array".
Fixed by adding validation for the returned value from `_get_cron_array()` and initializing an empty array if `false` was returned.

In this case, `parse_url()` is called with the `PHP_URL_PATH` as `$component`, but the returned value is subsequently checked against `false`.
In other words, this condition would previously always result in `true` and would lead to `null` potentially being passed to the PHP native `pathinfo()` function which expects a string.
On PHP 8.1, this would result in a test failure with a `pathinfo(): Passing null to parameter #1 ($path) of type string is deprecated` error.

The PHPUnit Polyfills are, since [51559], a required dependency for the WP test suite and, by extension, for plugin/theme integration test suites which are based on and use (parts of) the WP core test suite.
However, plugin/theme integration test suites may not use a full WordPress installation.
This commit:
* Removes the presumption that a full WP install, including `vendor` directory, will be available when the test `bootstrap.php` file is run.
* Makes the loading of the PHPUnit Polyfills autoload file more flexible by:
* Checking if the autoload class contained within the autoload file is already available before attempting to load the file.[[BR]]
This allows for plugin/theme integration test suites to load the `phpunitpolyfills-autoload.php` file from any location, as long as it is loaded before the WP core test `bootstrap.php` file is run.
* Allowing for the path to an arbitrary installation location for the PHPUnit Polyfills to be passed as a constant.[[BR]]
As long as the provided location is a valid file path and the `phpunitpolyfills-autoload.php` file exists in the provided location, that file will be loaded.[[BR]]
The constant can be declared in a plugin/theme integration test suite native test bootstrap file, or in the `wp-tests-config.php` file, or even in a `phpunit.xml[.dist]` file via `<php><const name="WP_TESTS_PHPUNIT_POLYFILLS_PATH" value="path/to/yoast/phpunit-polyfills"/></php>`.
* Adds a version check for the PHPUnit Polyfills to prevent a mismatch between the version of the package expected by WordPress and the version used by plugins/themes.[[BR]]
The version this checks for should be in line with the minimum version requirement for the PHPUnit Polyfills as declared in the `composer.json` file.[[BR]]
This version number should only be updated when new features added in later PHPUnit Polyfills releases are actually used in the WP core test suite.
* Adds appropriate error messages for every possible error condition.
* Upgrades the PHPUnit Polyfills to version 1.0.1, which now includes a version constant.

A general security rule is "Sanitize when you save, escape when you echo", and for the most part WordPress has well-named functions like `sanitize_email()` and others, with `esc_url_raw()` being a single exception that does not follow the naming.

Previously, the original "404" template key was lost when "Default template" is merged into the available templates array, as the `array_merge()` function renumbers numeric keys. Later, when we merge templates on the client side, this caused duplicate "404" templates to appear in the dropdown.
By replacing the `array_merge()` call with `array_replace()`, we make sure to keep the original numeric keys.

PHP 8.1 is expected to be released at the end of November 2021.
Enabling the tests to run in CI on PHP 8.1 allows us to get WordPress ready in time.
As an interim measure, while working through the PHP 8.1 issues, separate conditional steps are added to run the tests on PHP 8.1 with the `continue-on-error` option. That allows the test builds to show as "successful" if all non-PHP 8.1 test runs pass.

Since PHP 8.1, the `strftime()` and `gmstrftime()` functions are deprecated:
> The `strftime()` and `gmstrftime()` functions exhibit similar issues as `strptime()`, in that the formats they support, as well as their behavior, is platform-dependent. Unlike `strptime()`, these functions are available on Windows, though with a different feature set than on Linux. Musl-based distributions like Alpine do not support timezone-related format specifiers correctly. These functions are also locale-based, and as such may exhibit thread-safety issues.
>
> `date()` or `DateTime::format()` provide portable alternatives, and `IntlDateFormatter::format()` provides a more sophisticated, localization-aware alternative.
Reference: [https://wiki.php.net/rfc/deprecations_php_8_1#strftime_and_gmstrftime PHP RFC: Deprecations for PHP 8.1: strftime() and gmstrftime()]
> The `strftime()` and `gmstrftime()` functions have been deprecated in favor of
> `date()/DateTime::format()` (for locale-independent formatting) or
> `IntlDateFormatter::format()` (for locale-dependent formatting).
Reference: [1cf4fb739f/UPGRADING (L379-L381) PHP 8.1 Upgrade Notes].
Aside from one instance in SimplePie, the `strftime()` and `gmstrftime()` functions are only used within the test suite of WordPress to create formatted timestamps.
As the function is used in test code, this leads to test warnings like this on PHP 8.1:
{{{
Deprecated: Function strftime() is deprecated in path/to/tests/phpunit/tests/canonical/postStatus.php on line 37
}}}
These calls can all be safely converted to use a pattern along the lines of:
{{{#!php
<?php
date_format( date_create( 'time phrase or timestamp' ), $format )
}}}

Since PHP 8.1, `readonly` is a reserved keyword and cannot be used as a function name.
In order to avoid PHP parser errors, the `readonly()` function was extracted to a separate file and is now only included conditionally on PHP < 8.1.
This commit also:
* Moves the tests for the `__checked_selected_helper()` function and all the related functions to their own file.
* Switches to named data providers. This makes the output when using the `--testdox` option more descriptive and is helpful when trying to debug which data set from a data provider failed the test.

Prior to PHP 8.1, the default error handling mode was `MYSQLI_REPORT_OFF`. An error in the extension, database, query, or the database connection returned `false` and emitted a PHP warning:
{{{
$mysqli = new mysqli("localhost", "non-existing-user", "", "");
Warning: mysqli::__construct(): (HY000/2002): No connection could be made because the target machine actively refused it in ... on line ...
}}}
From PHP 8.1 and later, the default error mode is set to `MYSQLI_REPORT_ERROR|MYSQLI_REPORT_STRICT`. An error in the extension, database, query, or the database connection throws an exception:
{{{
$mysqli = new mysqli("localhost", "non-existing-user", "", "");
Fatal error: Uncaught mysqli_sql_exception: Connection refused in ...:...
}}}
WordPress has its own error reporting and gracefully handles the database errors by inspecting the error codes. Setting the MySQLi error reporting to off avoids fatal errors due to uncaught exceptions and maintains the current behavior.

Now that the tests can run PHPUnit cross-version and Composer will be used to install the test suite in CI, we could switch out the local copies of the [https://github.com/johnkary/phpunit-speedtrap PHPUnit speedtrap] package in favor of using the Composer package, which would prevent us having to make the WP local copies of the class compatible with later PHPUnit versions.
The SpeedTrap test listener was introduced to identify slow tests and take action on these to make them faster.
In practice, however, no notable action was ever taken based on the output of the test listener in all the years it was in place.
With that in mind, it was decided to remove the SpeedTrap test listeners without replacement.
If – at a future date – contributors would want to take action to speed up slow tests anyway, they can:
* Either add the package to their local install and use the output they receive locally to identify slow tests.
* Or use the PHPUnit native `@small` annotations in combination with the PHPUnit `PHP_Invoker` package as described in the PHPUnit documentation to [https://phpunit.readthedocs.io/en/stable/risky-tests.html#test-execution-timeout run tests with time limits].

Most of the aliasing in this `compat.php` file is redundant as PHPUnit 5.7.21+ contains a forward compatibility layer for these classes anyway (= PHPUnit provides both the namespaced and underscore named versions of these classes in PHPUnit 5.7.21+).
All the same, the file and the aliases are left in place for the time being, as plugins/themes using the WP test suite as the basis for their integration tests may rely on it, though WP itself should not really need it anymore, save for maybe one or two classes.

> When using this TestCase, if an individual test, or another TestCase which extends this TestCase, needs to overload any of the "fixture" methods, it should do so by using a snake_case variant of the original fixture method name, i.e. `set_up_before_class()`, `set_up()`, `assert_pre_conditions()`, `assert_post_conditions()`, `tear_down()`, and `tear_down_after_class()`.
>
> The snake_case methods will automatically be called by PHPUnit.
>
> > IMPORTANT: The snake_case methods should not call the PHPUnit parent, i.e. do not use `parent::setUp()` from within an overloaded `set_up()` method. If necessary, DO call `parent::set_up()`.

This commit:
* Lets the `PHPUnit_Adapter_TestCase` extend the `Yoast\PHPUnitPolyfills\TestCases\TestCase`, which makes this solution for the `void` return type available to the WordPress test suite.
* Removes the individual import and trait `use` statements for the Polyfill traits. These are no longer necessary as the `Yoast\PHPUnitPolyfills\TestCases\TestCase` already includes those.
Follow-up to [51559-51566].
