- This callback is invoked when TLS key material is generated or
received, in order to allow applications to store this keying material
for debugging purposes.
- It is invoked with an `SSLSocket` and a string containing the key
material in the format used by NSS for its SSLKEYLOGFILE debugging
output.
- This commit adds the Ruby binding `keylog_cb` and the related tests
- It is only compatible with OpenSSL >= 1.1.1. Even if LibreSSL implements
`SSL_CTX_set_keylog_callback()` from v3.4.2, it does nothing (see
648d39f0f0)
