Further performance improvements about genhttp HOT 3 CLOSED

In Kestrel we have the Transport first (unencrypted) and then SSL on top as a Middleware via SslDuplexPipe. They create an SslStream from this pipe so we can re-use our logic with authentication I guess. Have to dig into this but this seems promising.

First benchmarks show that this is even a little bit slower but yet comparable to the traditional, way easier approach - so it seems that the implementation of the .NET framework already runs I/O asynchronously or we are missing something else that limits the performance.

Will close this for now, #488 will probably bring the JSON test on par with ASP.NET.
