Sitsofe Wheeler 4714e12e8f socket: Use alternatives if MSG_NOSIGNAL is unavailable ...

Only Linux has MSG_NOSIGNAL as a socket flag (see
http://stackoverflow.com/questions/108183/how-to-prevent-sigpipes-or-handle-them-properly
) which makes compilation fail on other OSes. The BSDs and OS X have
SO_NOSIGPIPE which implements the same thing but others like
Solaris don't even have that (see
http://stackoverflow.com/questions/2205455/detecting-broken-pipe-in-solaris-send-call
)...

Work around this by checking using MSG_NOSIGNAL or SO_NOSIGPIPE if
available otherwise don't set anything at all so we at least continue
to compile.
