Rename init_progfile_dir to configuration_init. Add an argument which
specifies our configuration namespace, which can be "Wireshark"
(default) or "Logwolf".
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.
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.
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.
New link type DLT_ETW is added for write and read Event Trace on Windows.
This change updates MBIM dissector to decode a MBIM message from
a DLT_ETW packet.
