refactor(netx): use netxlite to build TLSDialer (#790) 
This diff modifies netx to use netxlite to build the TLSDialer.

Building the TLSDialer entails building a TLSHandshaker.

While there, hide netxlite names we don't want to be public
and change netx tests to test for functionality.

To this end, refactor filtering to provide an easier to
use TLS server. We don't need the complexity of proxying
rather we need to provoke specific errors.

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.
