Prevent SIGPIPE from socket writes on UNIX-likes

When writing to a disconnected socket, try to only get EPIPE rather
than taking down the process with SIGPIPE.

On recent Linux and other systems which have it, switch from writev to
sendmsg and pass MSG_NOSIGNAL.

On BSD-likes, set SO_NOSIGPIPE at connect time.

Use port-sockets.h macros in cc_kcm, sendto_kdc

Use SOCKET_CONNECT in cc_kcm.c and sendto_kdc.c to prevent SIGPIPE on
BSD-like systems. Use other port-sockets.h macros in cc_kcm.c in case
it is ever used on Windows.
