- add `curl_global_init()` and `curl_global_cleanup()` where missing. - check the result of `curl_global_init()` where missing. - return the last curl error from `main()`. - drop Win32-specific socket initialization in favor of `curl_global_init()`. - rename some outliers to `res` for curl result code. - fix cleanup in some error cases. Inspired by Joshua's report on examples. Closes #19053
