Rector the Contao\Session class

[aschempp]

Deprecated since Contao: 4.0

Before:

\Contao\Session::getInstance()->get('foo');
\Contao\Session::getInstance()->set('foo', 'bar');
\Contao\Session::getInstance()->remove('foo');
\Contao\Session::getInstance()->getData();
\Contao\Session::getInstance()->setData($foo);

After:

// $sesionBag would need to be an inline call I guess
$sessionBag = \System::getContainer()->get('request_stack')->getSession()->getBag(
    \Contao\System::getContainer()->get('contao.routing.scope_matcher')->isBackendRequest(
        \Contao\System::getContainer()->get('request_stack')->getCurrentRequest() ?? \Symfony\Component\HttpFoundation\Request::create('')
    ) ? 'contao_backend' : (
        \Contao\System::getContainer()->get('contao.routing.scope_matcher')->isFrontendRequest(
            \Contao\System::getContainer()->get('request_stack')->getCurrentRequest() ?? \Symfony\Component\HttpFoundation\Request::create('')
        ) ? 'contao_frontend' : 'attributes'
    )
);

$sessionBag->get('foo');

$sessionBag->set('foo', 'bar');

$sessionBag->remove('foo');

$sessionBag->all();

$sessionBag->replace($foo);

Additional information:

If $key if referer, popupReferer or CURRENT_ID, the access should be to $session->get(...) instead of the session bag. Not sure if that's really worth it though.
