Large handshake records may cause panics in crypto/tls. Both clients and
servers may send large TLS handshake records which cause servers and
clients, respectively, to panic when attempting to construct responses.
This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable
session resumption (by setting Config.ClientSessionCache to a non-nil
value), and TLS 1.3 servers which request client certificates (by setting
Config.ClientAuth >= RequestClientCert).
