Remove the old threading API
All OpenSSL code has now been transferred to use the new threading API, so the old one is no longer used and can be removed. We provide some compat macros for removed functions which are all no-ops. There is now no longer a need to set locking callbacks!! Reviewed-by: Richard Levitte <levitte@openssl.org>
