Fix stdio.h namespace for pre-threads POSIX (bug 20014).
stdio.h declares flockfile, ftrylockfile, funlockfile, getc_unlocked, getchar_unlocked, putc_unlocked and putchar_unlocked if __USE_POSIX, with comments "These are defined in POSIX.1:1996.". But __USE_POSIX is actually POSIX.1:1990, and these functions should not be declared for 1990 / 1992 / 1993 POSIX, XPG3 or XPG4. This patch fixes stdio.h to use __USE_POSIX199506 instead for those conditionals, as that is the correct conditional for the version of POSIX that introduced threads, and with threads those functions. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). [BZ #20014] * libio/stdio.h (getc_unlocked): Declare if [__USE_POSIX199506], not [__USE_POSIX]. (getchar_unlocked): Likewise. (putc_unlocked): Likewise. (putchar_unlocked): Likewise. (flockfile): Likewise. (ftrylockfile): Likewise. (funlockfile): Likewise. * conform/Makefile (test-xfail-XPG3/stdio.h/conform): Remove variable. (test-xfail-XPG4/stdio.h/conform): Likewise.
