- Replace sed hacks with real patches ( metadata retroactively pulled
  from git history and reconstructed to retain intent, as the existing
  sed commands had entirely ceased working, silently )

Upstream:
- Implement SSL_{CTX_,}set_psk_client_callback()
- Support NPN-less libressl
- Skip NPN-test with libressl
- Free ocsp_response only when allocated
- Lots of new bindings
- Fix key block size calculation with AEAD ciphers
- Fix test failures without '.' in @INC
