Feature test macros overhaul: stdio.h
Throughout, remove references to __STRICT_ANSI__ and use the proper internal macros and versions for C99, POSIX, ATFILE for the various *at functions, or LARGEFILE for fseeko and ftello. [v]asprintf are GNU extensions, but the *iprintf, *iscanf, and *asnprintf functions are unique to newlib. getw and putw were removed from POSIX.1-2001. funopen is BSD, and fopencookie is GNU.
