Gerald Combs 3086774fa6 wsutil: Add configuration namespaces.
Rename init_progfile_dir to configuration_init. Add an argument which
specifies our configuration namespace, which can be "Wireshark"
(default) or "Logwolf".

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.

Remove ws_diag_control.h from config.h because that was a workaround
for the lack of a public global header. Fix the resultant build errors.

João Valverde 5362d0c31b ws_getopt: Rename struct and macros
This is part of the API and should also be renamed to avoid conflicts.

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.

João Valverde c6a920686c wslog: Check environment initialization for errors

child mode.

João Valverde 759bb234d0 wslog: Check if we are initialized and add missing inits
Instead of receiving the program name from GLib, pass it explicitly
to ws_log_init() instead  and use that to initialize the GLib program
name.

ws_log_parse_args() will now exit the program when it encounters an
argument error if exit_failure >= 0.

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.

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.)

Guy Harris 065a762579 Extcap programs must write to the packet pipe in binary mode.
It doesn't matter on UN*X, but it definitely matters on Windows; we're
writing a pcap file, not a text file, so every byte we write should go
down the pipe as is.

Martin Kaiser 675e0649c0 make our version of nla_for_each_nested() public
caputils/ws80211_utils.c contains a re-definition of the linux kernel's
nla_for_each_nested() macro that applies the correct casts to allow
compilation with a C++ compiler.

Make this definition public by moving it into a new wsutil/netlink.h
file. Include the kernel's original definition before we overwrite it. This
way, it's not necessary for a .c file to include wsutil/netlink.h after
the system includes.

Use our nla_for_each_nested() version in extcap/dpauxmon.c to squelch the
following compiler warning:
