TYPO3 Core

The bootstrap functionality for resolving the RequestHandler
based on the request object added by the PSR-7 change.

The Bootstrap::run() method is now renamed to ->configure()
which does not call resolveRequest() anymore. Instead
resolveRequest() is called explicitly at a later point inside
every Application instance.

This way, the Application instance decides what kind of
Request object should be instantiated and hands it to
the Bootstrap, which in return resolves the RequestHandler.

The original RequestHandlerInterface is now moved to the Http/ namespace, and a RequestHandlerInterface for the
Console application has been introduced for handling.
