[patch] SOCK_CLOEXEC, SOCK_NONBLOCK and MSG_CMSG_CLOEXEC

Here are some more modifications to allow creating file descriptors with close-on-exec set. Like in linux/glibc, SOCK_CLOEXEC and SOCK_NONBLOCK can be OR'ed in socket() and socketpair()'s type parameter, and MSG_CMSG_CLOEXEC to recvmsg() makes file descriptors (SCM_RIGHTS) atomically close-on-exec.
