+Subject: [PATCH] Fix build with LibreSSL
+
+- Fix version checks as OPENSSL_VERSION_NUMBER in OpenSSL is always
+  0x20000000L.
+- FIPS support is removed from LibreSSL, do not use it.
+- Check for TLS1_3_VERSION define, not OpenSSL/LibreSSL version.
+  Theoretically even OpenSSL >=1.1.1 can be built with TLS 1.3 disabled.
