Implement a basic TLS 1.3 server handshake, only enabled if explicitly
requested with MaxVersion.
This CL intentionally leaves for future CLs:
- PSK modes and resumption
- client authentication
- compatibility mode ChangeCipherSpecs
- early data skipping
- post-handshake messages
- downgrade protection
- KeyLogWriter support
- TLS_FALLBACK_SCSV processing
It also leaves a few areas up for a wider refactor (maybe in Go 1.13):
- the certificate selection logic can be significantly improved,
including supporting and surfacing signature_algorithms_cert, but
this isn't new in TLS 1.3 (see comment in processClientHello)
- handshake_server_tls13.go can be dried up and broken into more
meaningful, smaller functions, but it felt premature to do before
PSK and client auth support
- the monstrous ClientHello equality check in doHelloRetryRequest can
get both cleaner and more complete with collaboration from the
parsing layer, which can come at the same time as extension
duplicates detection
Updates #9671
