Joachim Wiberg 35e4e0d073 Drop confusing splash cmdline and --enable-progress configure option
This patch reverts back to the progress/status behavior of Finit < v3.0
because this is what most users expect, including the maintainer.  The
resulting code and configure script is a lot simpler to understand and
maintain:

- No more --enable-progress or --enable-progress-classic configure
  flags.  Instead a progress_style variable in helpers.c that can
  be changed at compile time for those that really need it.
- No more 'splash' kernel commnand line option.  This turned out to
  be *very* confusing to many users who believed it was some sort of
  graphical splash screen à la Plymouth.

Also, when Finit debug is enabled we now have a global 'debug' flag
which now alo controls if klogctl() should be called to prevent the
kernel logs to the console or not.

Joachim Wiberg fccba7cd4c Replace %m GNUism with strerror(errno)
Even musl libc supports %m today, as well as most syslog daemons, but
that's no excuse to use this.

Jonas Holmberg ca210f5431 Add support for logging security related events
This patch introduces the LOG_CONSOLE syslog facility for logging common
events.  In industrial applications aiming for IEC 62443 compliance the
following events are central for system observability:

- Change of runlevel - i.e., starting up, shutting down, upgrade, etc.
  Facility: console, severity: notice
- Service starting
  Facility: console, severity: notice
- Service restarting
  Facility: console, severity: notice
- Service stopping
  Facility: console, severity: notice
- Service failed to start
  Facility: console, severity: warning

The use of facility console for this makes it easier to filter out when
forwarding syslog messages from an embedded system to a remote log sink.
Otherwise messages of facility daemon would be used, which include a lot
more, and mostly irrelevant, information.

Joachim Nilsson 516dbcc512 Remove --disable-quiet and quiet mode, default to a sane behavior
This patch is a follow-up to 1f1c2e0 which introduced the new semantics
for the very confusing quiet and silent modes.

The initial idea was to loosely follow the kernel cmdline 'quiet' option
and as a working concept this was good.  The resulting code, however,
became unnecessarily complex and the configure options impossible to
explain.

With this patch the quiet mode, and thus the --disable-quiet configure
option, is removed.  Finit now defaults to a sane behavior: services are
shown only at startup.   The --enable-silent option works like it did
before, silencing everything.

Joachim Nilsson 5e8cb63f9a Refactor, _d() et al to use logit() instead of err.h
This patch is the first in a series of changes to clean up the internal
logging APIs of Finit:

  1. Convert log macros to use logit() for everything (this patch)
  2. Set correct syslog() log level based on debug flag
  3. Do closelog()/openlog() when toggling debug flag to control LOG_PERROR
