Jirka Novak 6d0619cdd0 ciscodump: Added support for IOS XE and ASA
Changes:
- The tool now recognizes which software is running on a device - IOS, IOS XE
  or ASA. Based on it, it uses correct sequence of commands to setup
  capture, read captured packets and clear the capture.
- The tool reads packets on the fly so you don't have to wait till
  --remote-count of packets is reached.
- The tool reads timestamps from capture on the device for IOS and ASA (on
  IOS-XE, there is no timestamp in dump).
- Except Windows platform the tool handles early stop of capture on the device
  and clear of capture buffer on the device (it finish the capture).
- There are special interface names to allow the tool to generate
  specific capture types.
- Data collection and config cleanup is handled in two separated ssh
  sessions.
- Documentation updated.

Closes #17672.

João Valverde e921b804d0 Fix logging with extcaps
Extcaps require a log file when invoked in child mode. It also has
a specific flag to enable debugging, other that the wslog options.

Fix the logging to:
  1. Enable debug log level if --debug is used.
  2. Do not emit messages to the stderr if debug is enabled.

This brings extcap logging to the same feature level it had before
wslog replaced GLib logging.

João Valverde 8df2a73594 Use the musl in-tree getopt_long() everywhere
Besides the obvious limitation of being unavailable on Windows,
the standard is vague about getopt() and getopt_long() has many
non-portable pitfalls and buggy implementations, that increase
the maintainance cost a lot. Also the GNU libc code currently
in the tree is not suited for embedding and is unmaintainable.

Own maintainership for getopt_long() and use the musl implementation
everywhere. This way we don't need to worry if optreset is available,
or if the $OPERATING_SYSTEM version behaves in subtly different ways.

The API is under the Wireshark namespace to avoid conflicts with
system headers.

Side-note, the Mingw-w64 9.0 getopt_long() implementation is buggy
with opterr and known to crash. In my experience it's a headache to
use the embedded getopt implementation if the system provides one.

Guy Harris e4835191cb extcap: clean up the version number handling.
Have the version parameter be just the version number; other code
expects it to be that.

Have additional parameters for the "compiled with" and "running with"
information.

Add a extcap_version_print() routine to show the version message,
printing

	{exename} version {version}

and then printing

	Compiled with {compiled_with}

if "compiled with" information is supplied and printing

	Running with {running_with}

if "running with" information is supplied.

This fixes some messages, as well as fixing the display of extcap
modules in the About dialog.

Packet data is raw octets, meaning guint8s, not chars or gchars.

The last argument to recvfrom should be of type socklen_t on UN*X and

Guy Harris 2ee483a222 Move the Winsock initialization and cleanup to wsutil routines.
Those routines exist on both Windows and UN*X, but they don't do
anything on UN*X (they could if it were ever necessary).

That eliminates some #ifdefs, and also means that the gory details of
initializing Winsock, including the Winsock version being requested,
are buried in one routine.

The initialization routine returns NULL on success and a pointer to a
g_malloc()ated error message on failure; report the error to the user,
along with a "report this to the Wireshark developers" suggestion.

That means including wsutil/socket.h, which obviates the need to include
some headers for socket APIs, as it includes them for you.

Guy Harris bbc8cbfb9c If you use data_file_url(), you must first call init_progfile_dir().
And if you call init_progfile_dir(), you must call
init_process_policies() before that.

And even if you *don't* use data_file_url(), you might use it in the
future, or you might use other calls to get data file paths, so make
*all* the extcap programs make those calls.

(Yes, this is important on macOS, for example; it may also be important
on Windows.  On other UN*Xes we may just compile in the data file path,
but that's not true on *all* our platforms.)

Peter Wu e2e5b01d77 cli_main: remove real_main from stack traces for non-Windows
Restore the "main" name since that is used everywhere else except for
Windows. On Windows, "main" is renamed via a macro to avoid a conflict
with "wmain" and to allow it to be called in cli_main.c.

For those wondering, GUI applications (such as Qt) have a different
entry point, namely WinMain. In Qt5, src/winmain/qtmain_win.cpp defines
WinMain, but seems to convert its arguments from Unicode to CP_ACP
(ASCII). It might not support UTF-8, but I did not verify this.

Guy Harris a34cc98b2a Put the main() and wmain() routines for CLI programs into a separate file.
That means that code is only in one place, rather than having copies of
it in each of those programs.

CLI programs that, on Windows, should get UTF-8 arguments rather than
arguments in the local code page should:

	include the top-level cli_main.h header;

	define the main function as real_main();

	be built with the top-level cli_main.c file.

On UN*X, cli_main.c has a main() program, and just passes the arguments
on to real_main().

On Windows, cli_main.c has a wmain() function that converts the UTF-16
arguments it's handed to UTF-8 arguments, using WideCharToMultiByte() so
that it doesn't use any functions other than those provided by the
system, and then calls real_main() with the argument count and UTF-8
arguments.
