The setfsent() family of APIs was never standardized and on Linux only
GLIBC implement them. We've tried to overcome this limitation, and to
support uClibc/uClibc-ng and musl libc, by providing replacements APIs
in helpers.c.
However, and since we want to support alternative /etc/fstab files, the
setmntent() family of APIs is more widespread and supports reading from
any fstab or mtab file.

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.

Usability.
Remains backwards compatible for now, but finit.show_status is as of 4.3
deprecated. Likely to be removed int 5.0

Explicitly set arg to non-NULL value. The call to conf() later will
steer up the value to point to the full path of the user's finit.conf

When we added support for using popen() to run(), to log the output, we
forgot to update the error handling path. Found by Coverity Scan.

We don't want repeats of issue #236, so let's start by tracking down any
bugs hidden in logging functions.

On regular desktop systems, like Debian, the dbus-daemon forks off a
dbus-launch process to start up things like your desktop for you. This
process is not known to Finit and lingers in the background since it's
been reparented to init, and to top things off it seems to ignore any
SIGTERMs send to it.
Obviously this makes a shutdown on such systems very noisy, so this
patch changes the print() to a _d() so anyone debugging a system can see
it with `-- finit.debug` on the kernel command line, or `initctl debug`.

This split unmount is a bit crude, unfortunately. A user may have set
up a bind or overlayfs mount on top of a tmpfs -- so unmounting tmpfs
first will then always result in EBUSY.
Avoid logging busy errors and fake OK. We'll catch it later in the
second stage unmount.

Turns out that on Debian `ifdown -a` can block for quite a while at
shutdown/reboot. So we'd like to use the --force option. However,
the BusyBox ifdown tool doesn't support --force, only -f, which in
turn the regular ifdown tool doesn't support.
Regardless, we can allow network shutdown to run in the background
like bring-up, at reboot we want to reboot quickly and don't care
so much, and on runlevel change to single-user mode we can allow
for some lagging behind in the background.

- Mention why configure script is missing from GIT
- Adjust command line for enabling Finit debug
- Plus some minor formatting issues

Useful to debug system events after the system has started up and you
don't want to rebuild Finit to add the `-d` command line flag.

This is needed since 5ff27c4f when support for debugging Finit and the
kernel independently was added.
