This patch adds an `--enable-fallback-shell` option to confiugre.
When enabled Finit will start `/bin/sh` on the console, but only
if there are no active TTYs running in the current runlevel.
With this it will be easier to do board bringup with Finit, but it also
enables using the fallback shell in a rescue mode (runlevel) where no
TTYs are allowed to run.

This patch makes Finit require libuEv v1.4.2, a minor bugfix update, and
libite (-lite) v1.8.2, which is quite a bit more than just a few bug
fixes. The most relevant fixes are the removal of implicit logging for
touch(), makedir(), makefifo(), and erase() inline functions. The
release also removed implicit logging to stderr on error, as well as a
a few build fixes for running on musl libc.

This patch adds a very special debug mode to Finit. With this feature
enabled the actual duties of PID 1 is forked off early to a child. If
that child ever dies, usually due to a SIGSEGV, this wakes up the real
PID 1 which lauches a debug shell on the console.
Remember to disable 'quiet' and enable '--debug' on the kernel command
line to get all the debug logs -- which these days goes into the kernel
log in /dev/kmsg -- simply `cat /dev/kmsg` and use Ctrl-C to get the
shell prompt back.

Instead of ugly #ifdefs we now probe for mdev or udevd at runtime. Take
care to check for udev-finalize and location of udevd, it differs a lot
between distros.

This patch adds support for the following /etc/fstab API's on systems
that do not have them, e.g. musl libc on Alpine Linux.
- setfsent()
- getfsent(), and
- endfsent()

FIFOs, PID files, and other non-devices belong in /var/run (or /run
these days), not /dev -- as per FHS. Compat with Debian SysV init.

The TTY handling in Finit has always been a bit of a patch work. This
commit is an attempt at a first cleanup and simplification.
Included is a brand new built-in getty which should work fine on both
virtual and serial consoles. It is however completely untested on the
latter serial consoles.
Still TODO: add support for /etc/securetty, add support for actually
setting TERM when calling /bin/login.

By default the urandom plugin will use /var/lib/misc/random-seed across
reboots to seed /dev/urandom at boot.

Some vendors provide their own Netlink plugin to Finit. This patch
makes it possible to disable the default netlink plugin from being
built. However, even before this patch it was possible to overload
the plugin. This just discards it from being built.

The alsa-utils, dbus, lost (PID), resolvconf, and x11-common plugins are
rarely used in the main use-case for Finit (embedded head-less systems).
This patch disables them by default and makes them possible to enable by
configure --enable-$PLUGIN switches.

This patch replaces the verbose and kernel-quiet runtime options with
a (hopefully) more useful quiet and silent modes of operation.
By default Finit progressively shows all services it starts at boot, but
when boot has completed and services are started/restarted Finit prints
nothing. If `--disable-quiet` is given all started/restared/stoppping
messages are shown even after boot.
However, if `--enable-silent` is given Finit is completely silent even
at boot, no progress is shown, until the first service is started, which
on most systems is login.

Remove confusing `--with-aix-soname` option to configure. Replace with
hard-coded `aix-soname=both` => shared + static archives are build as to
be expected.

From now on the user is required to have libuEv and libite installed
before building and installing finit. This is for maintenance reasons.
