The 'initctl cond' commands were initiallý added to only manage usr
conditions. Recently the 'cond get' command was expanded to allow
reading general conditions as well.
However, since general conditions support three states the command
returned 'on' for conditions that were in flux. This patch fixes
that oversight.

The svc_set_state() function not only handles state transitions, it also
makes sure to cancel any outstaing service timeouts. Before the service
readiness support was added, service conditions were simply a single bit
of information, so clearing its conditions before changing states had no
impact. With readiness we have multiple bits of information that are
set as conditions.
When restarting a crashing service we set a timeout to retry restarting,
or ensure the service is now running. This means that the service can
signal READY before RUNNING is reasserted, but the RUNNING state can be
set also by the service state machine, so we need to ensure we do not
re-assert RUNNING if it's already set, and thereby clearing READY.

Issue #343 reports that readiness notification on crash/restart is lost.
This update to notify.sh reproduces that bug.

Over the years there have been multiple cases of invalid and/or unsafe
uses of signals and initctl commands at bootstrap and shutdown. These
cases cannot be safely supported. This commit locks down finit a bit
to avoid the most common cases.
If you run into this, please open a new discussion at GitHub and we'll
talk about it. Maybe I've been overzealous or you have another use-case
that warrants opening up some or parts of the API.

Not until fs_mount_all() has completed do we have /run, or /var/run, and
never after shutdown has been initiated.

As pointed out by Jack Newman in issue #338, when conditions are not
available (at boot before cond_init(), or shutdown when /var or /var/run
have been unmounted) we should not try to create any conditions.

Slightly different take on issue #334 making it optional, possible to
enable per system.
reboot-delay <0-60> # default: 0 (disabled)
When enabled (non-zero), runs after filesystems have been unmounted,
the root filesystems has been remounted read-only, and sync(2) has
been called, twice.

At this hook point the bootmisc.so plugin runs and creates all relevant
system directories. Much of the rest of system bootstrap relies on this
so it should be called together with the other FS hooks as soon as all
the filesystems have been mounted.

We use strtok() quite extensively in .conf parser. Parsing of a service
line is split in two, with the command arguments being parsed very late.
Adding a new sub-option parser, based on strtok(), risk losing command
arguments. Thus, change to use strtok_r() so that we always know where
the arg parser is.

This patch changes the way progress for unmounting filesystems is
displayed. To see each filesystem being unmounted Finit now must
be in debug mode.
A general "Unmounting filesystems ..." have been added instead as well
as progress for last hook script and finall call to reboot().

This change drops the confusing status progress output, which was always
OK since the actual modprobe operation runs in the background. No need
to show status of the "added a task to finit, found modprobe" command.

Instead of waiting until runlevel 2, 3, 4, or 5 to load modules with
this plugin, we should load modules as soon as possible, i.e., in
runlevel S. This also means that Finit will clean up all the tasks
so we don't have to see them in `initctl status`.
To allow users to revert to the old behavior, we add a new setting
set runlevel 2345
that per modules-load.d/file changes the runlevel for all modprobe
commands.

GitHub have now stepped their 'ubuntu-latest' image to Ubuntu 22.04.
With that comes the GLIBC bump to >= 2.34 which require aligning the
time bits and file offset bits to 64 bits. This is libuev v2.4.0.
We also make sure to align libite to the same version between the
workflows to avoid any nasty surprises.

All hook scripts are called with at least one environment variable set,
FINIT_HOOK_NAME, useful when reusing the same hook script for multiple
hook points. It is set to the string name, also used by the path, e.g.,
hook/net/up.
For all hook points from hook/sys/shutdown and later, FINIT_SHUTDOWN is
also set, to one of: halt, poweroff, reboot.

This protects against any hook scripts or services calling initctl when
we're going down. There's no way to service these requests anyway, so
no point in keeping the socket open. This way initctl can check for
the existence of the socket before attempting any IPC command.

Add support for /etC/os-release, with fallback to /usr/lib/os-release,
overriding some traditional modifiers with the os-release variant. The
traditional values for these modifiers are taken from uname, which on
Linux systems are pretty useless since they always return the kernel
name and version instead of the distro/OS values.
E.g., \s becomes PRETTY_NAME instead of 'Linux' and \v becomes the
pretty VERSION, while \r becomes VERSION_ID.

This change makes it possible to use the standard continuation character
in .conf files. For example:
service [23456] \
log:stderr \
<!pid/foo> \
bar \
-- This is the bar service, it depends on foo # comment that's dropped
Notice the additional support for comments on .conf lines. If you use
the comment character today you must change to escape it. Like this:
service :2 foo -- Foo \#2
