libcompat: Add a helper to get/set OS error state
On Unix like OSes, this saves/restores errno, on Windows both errno and GetLastError state are saved/restored. This should make it simpler to preserve that across function calls. Additionally, while tracking down uses of GetLastError, some places where the error code was printed out directly where replaced with instances of w32_perror.
