3b916f2e80 allow sending 1xx responses (#3047) 
Currently, it's not possible to send informational responses such as 103 Early Hints or 102 Processing.

This patch allows calling WriteHeader() multiple times in order to send informational responses before the final one.
It follows the patch for HTTP/1 (golang/go#42597) and HTTP/2 (golang/net#96).

In conformance with RFC 8297, if the status code is 103 the current content of the header map is also sent. Its content is not removed after the call to WriteHeader() because the headers must also be included in the final response.

The Chrome and Fastly teams are starting a large-scale experiment to measure the real-life impact of the 103 status code.
Using Early Hints is proposed as a (partial) alternative to Server Push, which are going to be removed from Chrome: https://groups.google.com/a/chromium.org/g/blink-dev/c/K3rYLvmQUBY/m/21anpFhxAQAJ

Being able to send this status code from servers implemented using Go would help to see if implementing it in browsers is worth it.

53270dde9e only read multiple packets at a time after handshake completion 
It's more important that acknowledge packets in a timely manner before
handshake completion. On the server side, we should send out the HANDSHAKE_DONE
frame as soon as possible.

ab46df5071 fix logging of dropped 0-RTT keys 
Client and server only possess write or read 0-RTT keys, respectively.
We should therefore only emit a single event when those are dropped.
