refactor: DNSTransport I/Os DNS messages (#760)
This diff refactors the DNSTransport model to receive in input a DNSQuery and return in output a DNSResponse.

The design of DNSQuery and DNSResponse takes into account the use case of a transport using getaddrinfo, meaning that we don't need to serialize and deserialize messages when using getaddrinfo.

The current codebase does not use a getaddrinfo transport, but I wrote one such a transport in the Websteps Winter 2021 prototype (https://github.com/bassosimone/websteps-illustrated/).

The design conversation that lead to producing this diff is https://github.com/ooni/probe/issues/2099

Package github.com/ooni/probe-engine/netx

OONI extensions to the net and net/http packages. This code is used by ooni/probe-engine as a low level library to collect network, DNS, and HTTP events occurring during OONI measurements.

This library contains replacements for commonly used standard library interfaces that facilitate seamless network measurements. By using such replacements, as opposed to standard library interfaces, we can:

  • save the timing of HTTP events (e.g. received response headers)
  • save the timing and result of every Connect, Read, Write, Close operation
  • save the timing and result of the TLS handshake (including certificates)

By default, this library uses the system resolver. In addition, it is possible to configure alternative DNS transports and remote servers. We support DNS over UDP, DNS over TCP, DNS over TLS (DoT), and DNS over HTTPS (DoH). When using an alternative transport, we are also able to intercept and save DNS messages, as well as any other interaction with the remote server (e.g., the result of the TLS handshake for DoT and DoH).

This package is a fork of github.com/ooni/netx.
