Do not restart a inetd service if the listening interface is changed.
Only bring down established connection which are no longer allowed,
i.e. do not touch already allowed established connections.

We cannot allow pid_runpath() to return its 'file' argument because that
may be a stack variable in a helper function.

On systems with the new /run hierarchy the compat symlink from /var/run
may be missing, or not yet be set up by bootmisc.so. This patch adds a
layer of safety to the condition layer, both set and get cond ops now
perform an adjustmed of the condition path if needed.

In case a user forgets to type in the service to enable, disable, or
touch, we try to be helpful and list available services instead of
bugging out.

All service/task commands are tracked by the state machine, but run
commands are a bit special since they must run in sequence. Hence,
we must increment their 'once' counter in service_start() instead.
This should fix the issue mentioned in #96 "took a long time before
the next line" -- because Finit was waiting for udevadm to reach a
once count > 0, which we didn't increment.

We must wait for udevd to be started before we call udevadm. However,
udevd doesn't create a PID file, so we must also fake this. There is
still a slight risk of a race condition: udevd not having properly
started before udevadm tries to connect, but it works OK in Debian.

Running Finit on a kernel or system without WDT support built-in should
not trigger an error message from Finit.

Issue #52 suggested calling service_reload_dynamic() automatically after
run-parts and /etc/rc.local. This may seem like a good idea, but not
only does it create extra overhead, it currently also freezes the boot
and fails to present a login prompt if a run-parts directory exists.
Yes, the directory can be empty, it just have to exist to trigger this
regression.
While trying to find the root cause I realized this was all just wrong.
If the user does something that requires reloading finit, they should
call `initctl reload` from the script instead.

When finit calls out to external tools, like `ifup $IFACE`, that tool in
turn may use other external tools. On systems with BusyBox our calling
`ifup $IFACE` will result in BusyBox casting a magic spell: if $SHELL is
unset it goes looking in the file /etc/passwd for the shell of $USER
which may not be set to a Bourne compatible UNIX shell, so commands like
`ip link ...` or `run-parts ...` will fail hard.
This patch adds SHELL=/bin/sh as a sane early default.

Some systems, usually those built around BusyBox, have mdev installed
but have an option to install udev. In those cases the user likely
prefers to use udev over mdev and this patch addresses that.

This patch introduces a new option to initctl; -b, --batch skips
screen_init(), which might otherwise leak ANSI screen resize codes
to the console.

As a precaution, services who are being stopped are automatically sent
a SIGKILL after 3 seconds if they refuse to go away willingly.
Unfortunately this backup mechanism was also enabled for inetd
services which are not backed by a real process. When the service was
freed the timer was not stopped, since it was not expected to be
armed. The timer would then trigger, causing a use-after-free on the
timer watcher containing a bogus callback pointer.
When an UDP inetd connection terminates we must make sure to unblock the
parent, which is (currently) blocked during the transaction.
This patch is a fix to a regression introduced in 2c904b5, for v3.1
