PR #8498 uses
SSL_SESSION_dupwhich is available since OpenSSL 1.1.1. I only confirmed BoringSSL build is broken, but it probably doesn't build with older OpenSSL as well.This PR introduces a wrapper function for
SSL_SESSION_dup, and it mimics the behavior ofSSL_SESSION_dupif the function is unavailable. I didn't test the implementation very seriously, but it should work if I understand the code before #8498.
