This patch allows disabling (enabled by default) the modprobe and tty
plugins. They are not particularly useful in container use-cases.

fastboot: once enabled, fsck would be skipped on filesystems listed in
/etc/fstab.
fsckfix: once enabled, 'fsck -ys' would be run instead of 'fsck -a',
and check the return value larger than 1 as a failure and goes
to login console.
They are both disabled by default, no functional changes unless an end
user choose to enable them.
The idea derives from Sysvinit's "FASTBOOT" and "FSCKFIX".

This patch removes the cognitive overhead of having to manually set your
OS heading, --with-heading="Foo OS vX.YY". As of this patch, Finit by
default extracts PRETTY_NAME from /etc/os-release. It is now possible
to also disable the heading entirely using --without-heading

Some systems may want to handle RTC and /dev/urandom by themselves, or
not at all as in the case of containers where the host does all this.

For most use-cases the kernel will give Finit its arguments as proper
command line args in argc + argv[], like any other program. However,
for some users, most notably Alpine Linux, there is a slightly broken
initramfs that cannot forward more than one argument using init_args,
for such systems you can re-enable the old behavior with a configure
switch --enable-kernel-cmdline -- it's not ideal but what can you do.
The main reason for removing this feature by default is to support
use-cases where Finit runs as the init for container apps that can read
/proc -- we do not want them to use the init args from the host.

Simplify build system.
The logit tool is, as of v4.0, installed into /libexec/finit/logit and
thus not part of the system $PATH. If a sysadmin or distro wants to
remove it from the system it's entirely possible since Finit always
checks for logit availability before attempting to use it.

Most major init systems have a way to start a rescue shell. This is
usally started when the string `rescue` is read from the kernel's
command line.
The traditional Finit way of handling this has been to skip certain
phases of the standard boot, skip /etc/finit.conf et al, and go for a
/lib/finit/rescue.conf instead. This pratice has been imroved over
the last few commits with a sulogin. However, there was no way to
resume boot, like most other init systems offer.
This patch implements a very simple rescue mode, utilizing the new
sulogin, replacing the old (and experimental) emergency shell. If
Ctrl-D is pressed at the maintenance login prompt the boot is now
resumed. The same goes for exit/Ctrl-D from the maintenace shell.
The preferred sulogin is the bundled /libexec/finit/sulogin, but
if that isn't installed, the first one in $PATH is used. If no
sulogin at all is found, Finit proceeds as before this patch, to
skip certains steps and go for a /lib/finit/rescue.conf. Hence,
al steps can be controlled by an administrator.

This changes the default to redirect output from run/task/services to

This patch changes the configure option to enable the built-in watchdog
from --enable-watchdog to --with-watchdog[=DEV]. This is the convention
for features that take arguments.
Also, improve log messages to aid debugging when finit-watchdogd does
not start properly. This means flushing logs to syslogd with closelog()

- 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

Both Debian and Builroot based systems use /etc/default and
Alpine Linux use /etc/conf.d, so let's just put both in by
default. If the directories exist we monitor them.
The --with-syconfig configure option is now disabled by default.

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.

In the v4 bump we removed tar.xz archives in favor of bringing back
