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.

As documented in the kernel docs and systemd[1], the default system
console is the first listed in /sys/class/tty/console/active, which
is the reverse order of console= given on the kernel cmdline.
Some distros don't have console= on their default command line in
their bootloader, e.g. Alpine Linux, some multiple, e.g Buildroot.
Instead of relying on the value given at configure time we probe
sysfs and open all (at most three) consoles listed. This way we
at least get the default console for our progress output.
- drop old --with-console from configure script
- drop /proc/cmdline fishing in favor of sysfs
- replace CONSOLE from configure with new console()

All Debian based distros are moving towards a /etc/network/interfaces.d/
world. Adding support for that is too complex, so we're reverting back
to calling 'ifup -a' or 'ifdown -a'. We still guard this by checking
both for 'ifup' and the existence of /etc/network/interfaces (which in
the new world only contains a line to source per-interface files).
By popular demand, this patch also changes to bring up/down networking
in the background. Useful for embedded system bringup and containers.

Some targets, like Raspberry Pi, have both serial and HDMI console
enabled. Depending on the order of arguments on the kernel cmdline
either one were selected the default 'stderr', which finit used.
This patch adds support for parsing the console= string(s) and
opening multiple outputs for system startup/progress. In the
end, however, a getty still needs to be started on each of the
consoles to use.

This patch to the banner "hello" is hopefully the last in this new style
progress. Previous efforts have used unicode symbols not available in
all fonts. This time we standardize on one that looks good both the
default Ubuntu Mono and Source Code Pro fonts. It's a bit small in my
preferred font, Envy Code R, but that might be a mistake in the font.
Not tested with PuTTY or Windows Hyper Terminal. I think they use the
Courier font by default, both of them, which I have tested.

Some ppl have their own '.' in service descriptions, adding anther just
messes things up and is confusing. The old style progress still adds
dots, but thats for padding up to [ OK ].

When starting up a system booted from initramfs / may already be
mounted (read-only), so we can safely fsck it before proceeding
to remount it as read-write later (possibly).

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 is a quite intrusive change. In addition to the already reserved
runlevels 0 and 6, halt and reboot, respectively, this patch reserves
runlevel 1 as *no networking*, like the traditional SysV init did. One
of the reasons for this change is the new 'single' user mode, introduced
earlier. Most users when entering 'S' or 'single' on the kernel cmdline
expect the single user mode (runlevel 1) to be without networking.
This leaves 2, 3, 4, 5, and 7, 8, 9 as fully user-configurable runlevels
with networking.
Of course, networking can still be enabled in runlevel 1 using ifconfig
or ifupdown, or change runlevel.

This patch changes the traditional look of the Finit boot sequence.
Now we stick to the screen width probed by screen_init(), or max
132 chars.
Also, some minor cleanup of the currently unused print_timestamp()
method used by printv() when showing [ OK ] or [FAIL] of services
at boot.

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
