Gerald Combs 6b4fae1a0b Windows: Switch from the WpdPack SDK to vcpkg's libpcap.
Switch from WinPcap's WpdPack SDK to a libpcap package built with vcpkg.
We explictly load wpcap.dll on Windows, so make sure we don't link with
pcap.lib.

Move timestamp code from capture-pcap-util-unix.c to
capture-pcap-util.c. Add timestap routines to capture-wpcap.c and make a
couple of other updates.

Guy Harris 0c889d6f5c Require at least libpcap 0.8/WinPcap 3.1.
2004 called, they want their libpcap/WinPcap back.

RHEL 6 initially shipped with libpcap 1.0; even old Enterprise(TM)
versions of OSes ship with something shinier than 0.7.x these days.

This lets us get rid of a bunch of #ifdefs and workaround code for
missing APIs.

Guy Harris 5ecbcaf483 Improve the secondary error messages for pcap errors.
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.

Guy Harris 79eab8ca07 Force HAVE_REMOTE to be defined when including pcap.h with remote support.
WinPcap made the mistake of having stuff in its public header fines
depend on a configuration #define, HAVE_REMOTE; this means that we need
to forcibly define it when building with remote capture support.

The tip of the libpcap master branch does not have that botch; hopefully
future versions of libpcap-for-Windows will be based on that libpcap and
thus lack that botch as well.

Defining HAVE_REMOTE in config.h is not the right fix, as it makes it
look like a *Wireshark* configuration option that code in Wireshark
should test, rather than a *WinPcap* configuration option that the
pcap.h that ships with the WinPcap SDK should have been changed, as part
of the build process, to correctly define or not, so that users of
WinPcap don't have to define it themselves.

{structurename} being the name of the structure type, complete with
"struct" if a typedef wasn't used, and with all letters mapped to upper

all letters mapped to upper case.

check_struct_has_member() lets you choose the name; choose the same name
that the autoconf macros use, and fix the code to check for them.

Guy Harris ba3aa03dcf Move more capture device handling to the caputils library.
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.

Guy Harris 78492d9dd2 Cope with newer Xcode not having the 10.6 SDK.
The latest Xcode, as of today, has only 10.9 and 10.10 SDKs, which means
that, if we build Wireshark and request a deployment minimum release of
10.6, we'll be building against an SDK in which libpcap has routines
that aren't available in 10.6 and that doesn't use weak linking for
them, so the resulting binary won't actually work on 10.6.

Use the run-time loader to find those routines (currently, only
pcap_set_tstamp_precision()) and call them only if we find them.

On other UN*Xes, we still assume that we'll be running only on the
release against which we were built and newer releases.

Guy Harris f6ce0cdacd Get rid of NO_INTERFACES_FOUND - it's not an error.
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.)
