Remove _IO_file_flags define.
This entirely mechanical (except for some indentation fixups) patch replaces all uses of _IO_file_flags with _flags and removes the #define. Installed stripped libraries and executables are unchanged by this patch. * libio/libio.h (_IO_file_flags): Remove macro. All uses changed to _flags.
