It strips off all suffixes, which is not useful behavior; it assumes
that nobody uses "." for any purpose other than separating a file name
from an extension - 1994 called, they want their version of Windows
back (and UN*X called, too...).

Strip off only extensions that correspond to file types we know about;
QFileInfo::baseName() strips off *all* extensions, where "extension" is
"anything preceded by a .", so it turns foo.bar.pcap.gz into foo, not
foo.bar. We don't want that; instead, we strip off only those
extensions that correspond to file types we know how to read, so we'd
strip off .pcap.gz in foo.bar.pcap.gz, and strip off .pcap in
foo.bar.pcap, leaving foo.bar in both cases.

In the Qt Follow TCP Stream dialog with the ASCII mode, sometimes
selecting the first few bytes would wrongly select a packet with a
higher frame number.
This happens because Qt iterates through the list of payloads, then
stores appends the payload data and maps the new cursor position to the
packet number. If the payload data was empty, then it would overwrite
previous cursor positions.
To fix this, do not add records for empty TCP payloads.

When two segments overlap each other, previously the second segment
would wrongly be appended to the first one while it should only append a
subset from the end of the second segment. (It is assumed that the very
first segment is received in time such that an extension on both the
left and right side of the previous stream is not possible.)
Make sure that "frag_follow_record->data" uses a subset (starting at the
end of the previous stream) instead of the full tvb contents. While at
it, add some documentation and restructure the logic to avoid code
duplication and unnecessary memory allocations.
(From bug 9882:) Tested with hao123-com_packet-injection-filtered.pcap,
it now ignores the new overlapping data. Likewise for overlap-2.pcap.
Tested with retransmission_with_additional_payload.pcapng (bug 13700).
Unfortunately, there is no extra expert info to warn about the
non-matching overlapping segment data, but that is a separate issue.

Don't test the "reserved for implementation" flags in the heuristic, and

For dialogs and auxiliary windows, if we have a live capture that hasn't
yet been saved to a permanent location, there's no good reason to show
the temporary file name in the title bar, as:
it's a random string that doesn't indicate where the capture was done
and that could confuse people (see, for example, the confusion in bug
14929, in which somebody referred to the "Follow TCP Stream" window as
the ".pcap dialog" because its title had ".pcap" at the end, due to
the capture file being a temporary file and its name showing up in the
title bar of that window);
it differs from what the main window title bar shows.
While we're at it, don't assume that the file name in the capture_file
structure is a UTF-8 string - some UN*Xes might not use UTF-8 for file
names.
