Detect console streams more reliably on Windows
GetStdHandle(STD_OUTPUT_HANDLE) doesn't work for stderr if stdout is
redirected. Use _get_osfhandle of the FILE* instead.
_isatty() is true for all character devices (including parallel and serial
ports). Check return value of GetConsoleScreenBufferInfo instead to
reliably detect console handles (also don't initialize internal state from
an uninitialized CONSOLE_SCREEN_BUFFER_INFO structure if the function
fails).
