So if we do a runtime detection of SOCK_CLOEXEC, but pipe2() is a stub inside of glibc, we hit a problem. For example: main() { getgrnam("portage"); if (!popen("ls", "r")) perror("popen()"); } getgrnam() will detect that the kernel supports SOCK_CLOEXEC and then set both __have_sock_cloexec and __have_pipe2 to true. But if glibc was built against older kernel headers where __NR_pipe2 does not exist, glibc will have a ENOSYS stub for it. So popen() will always fail as glibc assumes pipe2() works. While this isn't too much of an issue for some arches as they added the functionality to the kernel at the same time, not all arches are that lucky. Since the code already has dedicated names for each feature, delete the defines wiring these three features together and make each one a proper dedicated knob. We've been carrying this in Gentoo since glibc-2.9. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

	__libc_clntudp_bufcreate_internal. * include/sys/socket.h: Declare __have_sock_cloexec. * socket/Makefile (aux): Add have_sock_cloexec. * socket/have_sock_cloexec.c: New file. * sunrpc/clnt_udp.h (clntudp_bufcreate): Now a wrapper around __libc_clntudp_bufcreate. (__libc_clntudp_bufcreate): Former implementation of clntudp_bufcreate which takes an additional parameter. Create socket with non-blocking mode and close-on-exec flag set, if wanted. * sunrpc/Versions: Export __libc_clntudp_bufcreate@GLIBC_PRIVATE. * nis/ypclnt.c (yp_bind_client_create): Use __libc_clntpudp_bufcreate instead of clntudp_create. The socket has already the close-on-exec flag set if SOCK_CLOEXEC is defined.
