If a server pipelines future responses within the STARTTLS response, the former are preserved in the pingpong cache across TLS negotiation and used as responses to the encrypted commands. This fix detects pipelined STARTTLS responses and rejects them with an error. CVE-2021-22947 Bug: https://curl.se/docs/CVE-2021-22947.html
