Add a -q flag to dumpcap, to squelch its reporting of the packet count,

and add support for SIGINFO, so, if your OS supports SIGINFO, you can
get the packet count by typing ^T.

+When capturing packets, don't display the continuous count of packets
+captured that is normally shown when saving a capture to a file;
+instead, just display, at the end of the capture, a count of packets
+captured.  On systems that support the SIGINFO signal, such as various
+BSDs, you can cause the current count to be displayed by typing your
+"status" character (typically control-T, although it
+might be set to "disabled" by default on at least some BSDs, so you'd
+have to explicitly set it to use it).
