After reports from the field, see issue #397, of lockups at reboot,
we've decided to drop this code from PID 1. It was added before the 4.x
series, when the current progress output was introduced. For the older
style progress it served a purpose since the placement of [OK]/[FAIL]
was on the right hand side.

When there is no log daemon, and we are running in a container, or we
cannot log to the kernel ring buffer, then we log to stderr. This patch
improves the log output by prefixing each message with a timestamp.

Drop the config.h include from helpers.h after a report from a colleague
trying to build an external plugin from the latest GIT sources.
Instead, make sure config.h is included, and properly commented, in all
.c files that have configure #ifdefs and other deps. Also, move more
ot the includes from helpers.h to their respective .c file instead to
reduce the amount of headers an external plugin pulls in.

Calling `initctl debug` is supposed to toggle Finit debug messages on
the boot console. This broke in ae09272b when improving support for
running Finit in containers.
Part of this change is a slight refactor of who calles log_init() when
starting up, and when to call ttinit(). We now call ttinit() every time
we toggle debug.
Also, toggling back to normal logging had a bug. The new default log
level for Finit is LOG_INFO, but toggling back set it to LOG_NOTICE.

When running in a container we still want to use any syslog daemon
available for our logging needs. However, the time between the first
logit() in Finit and any such daemon having started can be long. In a
normal (non-containerized) setup we log to the kernel ring buffer, but
that's not available in a container scenario. At least not for
unprivileged containers. So we need to detect all these cases and be
prepared to fall back to log to the console, either using these LOG_CONS
flag to openlog(), or by simply calling vfprintf() to stderr.

Due to an unfortunate name clash with the DirectFB project LiTE, the
libite (-lite) project had to change its header namespace from
lite/*.h -> libite/*.h
This patch adds support for the new namepace in Finit, triggered by the
define _LIBITE_LITE, from the .pc file read by pkg-config. This should
only be needed on systems that install libite without the compatibility
symlink lite -> libite/ in the staging include directory.

We've had several logit() messages of LOG_INFO level that never
really made it to syslog because we classified it as "debug".

If we don't extract the level (disregarding facility), statements such as
"logit(LOG_CONSOLE | LOG_NOTICE, ...)" would never reach the kernel log.

- Refactor screen_init()
- use native impl. of TTY probing from pimd project
- check if TIOCWINSZ works
- check if we're running in watch(1), for initctl
- check if ANSI goto(999,999) escape seq. works (invasive)
- fallback to 80x24
- Drop screen_exit()
- Rename screen_init() to get_width(), for now, matching pimd
- Relocate call in main() to banner(), first fn to write to TTY

We don't want to show progress (starting/stopping/restaring) at
runtime, since Finit v3. Many systems hooked up to a console
get confused by sudden output, or even ansi escape sequences.
This patch drops code added recently which caused a regression
in this policy. The resulting code is even more readable.

Modeled after systemd.show_status, currently without the 'auto' setting.

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.

Starting in debug mode and disabling debug at runtime did not exhibit
the same behavior as if starting in normal mode and toggling debug mode
at runtime. This patch adds toggling of silent mode (progress output)
to runtime debug toggling.

The screen_init() call for each print() & C:o caused serious screen
artefacts in debug mode. This patch reworks f858d94 to only re-init
screen when toggling debug.
Also, avoid screen_init() completely if started in debug mode.

This patch builds on top of the recently introduced "silent by default"
and support for kernel cmdline `splash` to disable silent operation.
At shutdown/reboot `log_exit()` is called, the intention is to re-enable
progress output so the user can see what's going on. So, we need to re-
set `silent` to the same setting as log_init() started with, hence the
new `muffler()`.

Ways to log:
- Set debug, using kernel cmdline, or edit the sources
- Change loglevel severity, default blocks > LOG_NOTICE

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.

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
