The context-cancelled watchdog goroutine may start running way after the
handshake has finished and the associated context has been cancelled (by the
executeDial() function in go-libp2p-swarm usuaully).

This results in the connection being closed right after being stablished.

fix CI after deprecating gx

replace gx instructions with note about gomod

implement the new handshake

When resuming a session using session tickets, no certificate chain is
presented, and the callbacks needed to verify the peer identity would
not be called.

use a prefix when signing the public key

use ChaCha if one of the peers doesn't have AES hardware support

improve peer verification

add an example (mainly for development)

use TLS 1.3

TLS 1.3 support was recently made opt-in in Go 1.12, so we need to
explicitly enable it.

TLS 1.3 will require Go >= 1.12, so we don't need any fixes that were
specific to Go 1.10 any more.

remove unneeded marshaling / unmarshaling when generating cert chain

avoid using interface{} when generating certificates
