docs: Returns the pointer to the {@code SSL_CTX} object for this {@link ReferenceCountedOpenSslContext}.
  Be aware that it is freed as soon as the {@link #release()} method is called.
  At this point {@code 0} will be returned.
  
  @deprecated this method is considered unsafe as the returned pointer may be released later. Dont use it!
