>+        [Curl] Add OpenSSL/LibreSSL multi-threading support
>+        https://bugs.webkit.org/show_bug.cgi?id=185138
>+
>+        The older OpenSSL manual says the locking_function and threadid_funcion should
>+        set when use it in multi-threading environment. This applies to LibreSSL also.
>+        https://www.openssl.org/docs/man1.0.2/crypto/threads.html
>+
>+        For unix and other similar os, the default threadId_function implementation is
>+        good enough. We'll set custom callback only for Windows OS.
>+
>+        Note it's not required for OpenSSL 1.1.0 and after.
