Move existing `Curl_rename()` `rename()` wrapper from lib to curlx/fopen, and make it a curlx macro/function. To allow using the local worker function to fixup long filenames on Windows. Then fix the Windows-specific rename implementation to support long filenames. This operation may happen when using a cookie jar, HSTS cache or alt-svc cache, via libcurl or the curl tool. Before this patch, when passing a long filename to the above options, a `<random>.tmp` file was left on the disk without renaming it to the filename passed to curl. There was also 1 second delay for each attempted rename operation. Also: - checksrc: ban raw `rename()` and `MoveFileEx*()` functions. - Note: `Curl_rename()` returned 1 on failure before this patch, while `curlx_rename()` returns -1 after, to match POSIX `rename()`.
