Cache: prefix-based temporary files. On Linux, the rename syscall can be slow due to a global file system lock, acquired for the entire rename operation, unless both old and new files are in the same directory. To address this temporary files are now created in the same directory as the expected resulting cache file when using the "use_temp_path=off" parameter. This change mostly reverts 99639bfdfa2a and 3281de8142f5, restoring the behaviour as of a9138c35120d (with minor changes).
