Log Message:
* Arrange for interfaces that create new file descriptors to be able to
  set close-on-exec on creation (

    - 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,
    - 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

* Bump libc version for the new syscalls.
