It just means "pcap didn't give me any interfaces, and didn't report an
error". Hopefully, in the future, there will be pcap APIs that
distinguish between the (admittedly unlikely, these days) case of "there
really *are* no interfaces on which *anybody* can capture" and "you
don't have sufficient permission to capture", and we can report the
latter as an error. (Given that pcap supports more than just "regular
interfaces", though, there are cases where you don't have permission to
capture on those but you have permission to capture raw USB traffic, for
example, so perhaps what's really needed is per-interface indications of
permissions.)

Have --version print the version number, the copyright information, the
"compiled with" information, the "running on/with" information, and the
compiler information.
Have --help print the version number, a one-line summary of what the
program does, a reference to http://www.wireshark.org for more
information, a Usage: line, and a list of command-line options.
This means programs doing that don't need to include version.h; that's
left up to get_ws_vcs_version_info() to do.

That way, the code that constructs the runtime version string doesn't
itself have to call libpcap and libz, and could be usable in programs
that don't call them.
While we're at it, add "with" to the run-time version information for
GnuTLS and libgcrypt, to match the compile-time version information, and
add the version information from libwireshark to TShark.

Add a routine get_ws_vcs_version_info() that, for builds from a tree
checked out from Wireshark's version control system, returns a string
that includes both the Wireshark version number and an indication of
what particular VCS version was checked out, and just returns
Wireshark's version number for other builds.
Use that routine rather than manually gluing VERSION and the Git version
number together.
("vcs", not "git", just in case we do something bizarre or mercurial
some day. :-))
