Xi Ruoyao 64b1a44183 libio: Add nonnull attribute for most FILE * arguments in stdio.h ... During the review of a GCC analyzer test case, we found most stdio functions accepting a FILE * argument expect it to be nonnull and just segfault when the argument is NULL. Add nonnull attribute for them. fflush and fflush_unlocked are well defined when __stream is NULL so they are not touched. For fputs, fgets, fread, fwrite, fprintf, vfprintf, and their unlocked version, if __stream is empty but there is nothing to read or write, they did not segfault. But the standard disallow __stream to be empty here, so nonnull attribute is also added for them. Note that this may blow up some old code already subtly broken. Also add __nonnull for _chk variants and __fortify_function versions for them.
