* Arrange for interfaces that create new file descriptors to be able to
set close-on-exec on creation (http://udrepper.livejournal.com/20407.html). - Add F_DUPFD_CLOEXEC to fcntl(2). - Add MSG_CMSG_CLOEXEC to recvmsg(2) for unix file descriptor passing. - Add dup3(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK. - Add pipe2(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK. - Add flags SOCK_CLOEXEC, SOCK_NONBLOCK to the socket type parameter for socket(2) and socketpair(2). - Add new paccept(2) syscall that takes an additional sigset_t to alter the sigmask temporarily and a flags argument to set SOCK_CLOEXEC, SOCK_NONBLOCK. - Add new mode character 'e' to fopen(3) and popen(3) to open pipes and file descriptors for close on exec. - Add new kqueue1(2) syscall with a new flags argument to open the kqueue file descriptor with O_CLOEXEC, O_NONBLOCK. * Fix the system calls that take socklen_t arguments to actually do so. * Don't include userland header files (signal.h) from system header files (rump_syscallargs.h). * Bump libc version for the new syscalls.
