* Decouple connection objects from the server (#2535)
- Making progress towards being able to use the connection objects on the client side.
* Wait for input writer to complete before calling OnConnectionClosed (#2566)
* Wait for the ConnectionClosed token to stop tracking connections (#2574)
- The prior strategy of waiting for the pipe completed callbacks doesn't work
because blocks are returned to the memory pool after the callbacks are fired.
* Consistently handle connection resets (#2547)
* Provide better connection abort exceptions and logs

- Most of the shared code is in the HttpProtocol class (former Frame)
- Virtual calls handle protocol-specific things
- Move the ProcessRequestsAsync loop to HttpProtocol
- Implement HTTP/1.x request processing in Http1Connection and HTTP/2
in Http2Stream, with Http1Connection<T> and Http2Stream<T> subclassing
those classes in order to handle the generic HttpContext parameter
- Split MessageBody into Http1MessageBody and Http2MessageBody,
with MessageBody containing shared member variables and methods
