Feature: #92984 - PSR-7 Request available in Frontend ContentObjects 

Description 

The main Request object of a web-based PHP process is now handed into all ContentObjects and ContentObjectRenderer classes.

In addition, any kind of "userFunc" methods initiated from ContentObjectRenderer , basically all custom Frontend PHP code, now receives the request object that was handed in as third method argument.

The ContentObjectRenderer API now has a getRequest() method.

Example:

page.10 = USER
page.10.userFunc = MyVendor\MyPackage\Frontend\MyClass->myMethod

<?php

namespace MyVendor\MyPackage\Frontend;

class MyClass
{

    public function myMethod(string $content, array $configuration, ServerRequestInterface $request)
    {
        $myValue = $request->getQueryParams()['myGetParameter'];
        $normalizedParams = $request->getAttribute('normalizedParams');
    }
}

This functionality should be used in PHP code related to Frontend code instead of the superglobal variables like $_GET / $_POST / $_SERVER , or TYPO3s API methods GeneralUtility::_GP() and GeneralUtility::getIndpEnv() .

Impact 

Any kind of custom Content Object in PHP code can now access the PSR-7 Request object to fetch information about the current request, making TYPO3 Frontend aware of PSR-7 standardized request objects.
