`$request` and `$query` parameter bags could be hard to get for a newcommer, who's used to `$_POST` and `$_GET` variables. Some people claim naming makes no sense (see #9671).

For consistency I documented all public properties.

Just as the title say, there was a kernel.event_listener string hardcoded in an error message although everywhere else in this class it is stored in the `$listenerTag` property.

[Process] Add support SAPI cli-server

As of PHP 5.4.0, the CLI SAPI provides a built-in web server.
```php
PHP_SAPI == 'cli-server'
```
PHP can be used portable without installation on PC. For example, the [assembly](http://windows.php.net/download/) does not require installation in the system on Windows. In this case `PHP_BINARY` contains the path to the PHP executor, and all the other search methods will not return result.

In #9792 RegisterListenersPass was moved from HttpKernel to EventDispatcher. Since FrameworkBundle uses that class the dependency needs to be rises to 2.5.
