wire: remove FrameParser interface, expose FrameParser struct (#4284) 
Instead, expose the FrameParser struct. This allows us to embed it
directly into the connection struct, avoiding a pointer indirection.

send out the CONNECTION_REFUSED error when refusing a connection (#4250) 
So far, we used Connection.destroy, which destroys a connection without
sending out a CONNECTION_CLOSE frame. This is useful (for example) when
receiving a stateless reset, but it's not what we want when the server
refuses an incoming connection. In this case, we want to send out a
packet with a CONNECTION_CLOSE frame to inform the client that the
connection attempt is being rejected.

remove shutdown method on the Connection (#4249) 
There's no need to have a dedicated shutdown method, as the use case
(shutting down an outgoing connection attempt on context cancellation)
can be achieved by using Connection.destroy.

logging: pass the packet number to ConnectionTracer.DroppedPacket (#4171) 
In most cases the packet number is not known when a packet is dropped,
but it's useful to log the packet number when dropping a duplicate
packet.

rename Connection.{Send,Receive}Message to {Send,Receive}Datagram (#4116) 
This is more consistent with both the RFC and the rest of the API. For
example, the option in the Config is already name EnableDatagrams, and
the property in the ConnectionState is named SupportsDatagrams.

470ae7b39b enable packet pacing, for packets sent before handshake completion 
It's not clear why this was disabled so far. The pacer should have some
allowance for bursts, and it is expected that the handshake flights fit into
this burst budget and therefore won't be delayed by the pacer.

However, when using 0-RTT, it actually makes sense to start pacing right
away, to avoid inducing packet loss very early in the connection.
