remove the H3_EARLY_RESPONSE error

implement tracing for congestion state changes

The RTTStats are used by the logging package. In order to instrument the
congestion package, the...

remove the N connection simulation from the Reno code

remove the SSLR (slow start large reduction) experiment

We apparently copied that code over from Chromium's Cubic
implementation, but we certainly don't...

add an integration test that randomly sets tracers

privatize some methods in the congestion controller package

fix out-of-bounds read when creating a multiplexed tracer

log all reasons why a connection is closed

This also allows us to get rid of the ReceivedStatelessReset() method.

don't block sendQueue.Send() if the runloop already exited.

move the SupportedVersions slice out of the wire.Header

add a flag to disable conn ID generation and the check for retired conn IDs

put the session in the packet handler map directly (for client sessions)

don't send write error in CONNECTION_CLOSE frames

This can lead to a deadlock where session.shutdown() never exits
