da25787a3d testutils: make the package public (#4290) 
This package can be useful outside of quic-go. We're not making any API
guarantees at this point.

be4838bd64 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.

746290b78a never allow 0-RTT when using Dial, even if the session ticket allows it (#4125) 
When resuming a TLS session using Dial (and not DialEarly), 0-RTT should
be disabled at the TLS layer, even if the session ticket allows for
0-RTT resumption.

This bug is not critical, since Dial doesn't return an EarlyConnection,
so the client wouldn't be able to actually send 0-RTT data in practice.

1c631cf9cb 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.

4a046185b7 ackhandler: fix ECN mangling detection when packets are lost (#4089)

abfe1ef548 remove Config.MaxRetryTokenAge, set it to the handshake timeout (#4064) 
There is no good reason to manually set the validity period for Retry
tokens. Retry tokens are only valid on a single connection during the
handshake, so it makes sense to limit their validity to the configured
handshake timeout.
