Description:
------------
With TLS 1.3 session tickets get sent after the handshake has completed (in TLS 1.2 this only happens upon renegotiation). With connections that never read from the socket (like the FTP data connection) this data will never actually be trained. However closing the socket without training (unidirectional shutdown) causes an ECONNRESET on server side which might lead to data truncation.

As explained in https://www.openssl.org/docs/manmaster/man3/SSL_shutdown.html PHP instead should call SSL_read after calling SSL_shutdown until we've received the servers close_notify alert.

For reference see CURLs implementation: https://github.com/curl/curl/blob/e2dd435d473cdc97785df95d032276fafb4b7746/lib/vtls/openssl.c#L1267

Test script:
---------------
ProFTPd with OpenSSL 1.1.1 and TLS 1.3.

Script is as simple as: ftp_put($ftp, "dest", "source", FTP_BINARY);

Results in: Transfer aborted. Link to file server lost
