* rt/Versions (librt): Export __mq_open_2@@GLIBC_2.7.
* rt/Makefile (headers): Add bits/mqueue2.h. * rt/mqueue.h: Include bits/mqueue2.h if -D_FORTIFY_SOURCE=2, optimizing with GCC and __va_arg_pack_len is defined. * rt/bits/mqueue2.h: New file. * rt/mq_open.c (__mq_open): Renamed from mq_open. (mq_open): New strong_alias. (__mq_open_2): New function. * sysdeps/unix/sysv/linux/mq_open.c (__mq_open): Renamed from mq_open. (mq_open): New strong_alias. (__mq_open_2): New function. * debug/Versions (libc): Export __fortify_fail@@GLIBC_PRIVATE. * Versions.def (librt): Add GLIBC_2.7 version. * debug/fortify_fail.c (__fortify_fail): Add libc_hidden_def. * include/stdio.h (__fortify_fail): Add libc_hidden_proto. * misc/sys/cdefs.h (__errordecl, __va_arg_pack_len): Define. * io/fcntl.h: Include bits/fcntl2.h when __va_arg_pack_len is defined rather than when not C++. * io/bits/fcntl2.h (__open_alias, __open64_alias, __openat_alias, __openat64_alias): New redirects. (__open_too_many_args, __open_missing_mode, __open64_too_many_args, __open64_missing_mode, __openat_too_many_args, __openat_missing_mode, __openat64_too_many_args, __openat64_missing_mode): New __errordecls. (open, open64, openat, openat64): Rewrite as __extern_always_inline functions instead of function-like macros.
