On Windows, if WinPcap isn't installed, warn about that for errors other
than failed attempts to start capturing.
On HP-UX, if we appear to have an old version of libpcap, warn about
that for errors other than failed attempts to start capturing.
If we know the error is a permissions problem, don't make suggestions
appropriate to other problems.
If we know the error is *not* a permissions problem, don't make
suggestions appropriate to permissions problems.
For permissions problems, or possible permissions problems, on Linux,
suggest doing dpkg-reconfigure wireshark-common if you've installed from
a package on Debian or a Debian derivative such as Ubuntu.

Move the code to open capture devices and get properties of capture
devices there, joining the code to get a list of capture devices.
This lets us do a better job of handling pcap_create() in WinPcap,
including handling both WinPcap with pcap_create() and WinPcap without
pcap_create() at run time, just in case somebody tries using WinPcap 3.x
with a Wireshark built with WinPcap 4.x.
It also could make it easier to use libpcap/WinPcap directly in
Wireshark and TShark, if we have versions of libpcap/WinPcap that run
small helper utilities to do privileged functions, allowing programs
using them never to need elevated privileges themselves. That might
make it easier to fix some issues with running TShark when not saving to
a file (we could avoid the file entirely) and with delays when stopping
a capture in Wireshark (Wireshark could stop writing to the file as soon
as you click the stop button, rather than letting dumpcap do so when the
signal gets to it).
It might also make it easier to handle future versions of
libpcap/WinPcap that support using pcap_create()/pcap_activate() for
remote captures, and other future extensions to libpcap/WinPcap.
Rename some XXX_linktype routines to XXX_datalink to indicate that they
work with DLT_ values rather than LINKTYPE_ values; future versions of
libpcap might use LINKTYPE_ values in newer APIs.
Check for pcap_create() on all platforms in CMake.

Some of those routines are used only in dumpcap; others are used in
TShark and Wireshark as well.
