 Fix https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=3315 -
make Save-As/Displayed/All-Packets save not only the displayed packets but also any other packets needed (e.g., for reassembly) to fully dissect the
 displayed packets.
This works only for the "All packets" case; choosing only the Selected packet, the Marked packets, or a range of packets would require actually storing which packets depend on which (too much memory) or going through the packet list many times (too slow). Also, this behavior is always the case: you can't save the displayed packets without their dependencies (I don't see why this would be
 desirable).
So far this is done for SCTP and things using the reassembly routines (TCP has
 been tested).
The Win32 dialog was modified but hasn't been tested yet. One confusing aspect of the UI is that the Displayed count in the Save-As dialog does not match the number of displayed packets. (I tried renaming the button "Displayed + Dependencies" but it looked too big.) The tooltip tries to explain this and the fact that this works only in the All-Packets case;
 suggestions for improvement are welcome.

I thought of another way to implement this UI: basically to show the count of Displayed packets followed by " (+N dependencies)" (if there are any dependencies): see attached for an example. Is this better?

Only problem is that when I try this on Windows the "Packet Range" box does not expand for the extra width so (using the sample sample capture) only "39 (+ 169" ends up being displayed. Anyone know why that might be and/or how to fix it?

Ah, okay, r42799 shows me how/where I could change the Win32 dialog (well, I didn't look in detail). But I'm still not sure if it's a good idea. Any thoughts? (Screen shot attached again for reference.)
