Check whether we have "pcap_breakloop()", and use it if we do - it's a
safer way to terminate "pcap_loop()" in a signal handler (it just sets a
flag, it doesn't muck with data structures that might have been in the
middle of being updated).
Have "setsignal()" not request SA_RESTART, so that if we call
"pcap_breakloop()" in a signal handler and then return, we don't restart
a call that was waiting for captured packets, we just make that call
EINTR out.
