This change opens up the runlevel change API from bootstrap. The twist
is that the change is only queued, i.e., the call `initctl runlevel 9`
during bootstrap only changes the configured runlevel to go to after
bootstrap has completed.
Effectively, this change allows overriding the `runlevel` directive in
/etc/finit.conf without having to change the file.

This patch extens the SysV compatibility support in Finit by adding
support for limiting `runparts` to run only SNNfoo, or KNNfoo, style
scripts from a directory.
Additionally, by default `runparts` now runs entirely in the background
without any progress. To enable progress, an optional argument has been
added to the runparts command line.

The rescue mode that can be invoked from the kernel command line is
potentially unsafe. Many systems lock the root user account, or use
another account for managing, e.g. 'admin'. The sulogin program(s)
would on such systems give the user a root prompt.
In #357 we added support for setting a custom sulogin user, but for some
systems that is not enough. On many embedded systems the /etc/passwd
and shadow files are populated at bootstrap and at the time rescue mode
runs, these files will be unpopulated.
The only, truly safe, approach on such systems is to disable rescue mode
completely. Otherwise intricate Finit plugins have to be used that run
before rescue mode is started -- increasing the complexity of the system
as a whole.

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.

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

This change adds support for a new command line option finit.config=PATH
which can be used to tell Finit to start with /etc/factory.conf instead
of /etc/finit.conf.
For the complete experience a new top-level configuration file directive
`rcsd PATH` has aslo been added. It in turn can be used by factory.conf
as follows to override /etc/finit.d:
rcsd /etc/factory.d

This patch adds the oncrash:script option to call the post:script
action, if defined, for a crashing service. The EXIT_CODE variable
sent to the script is set to `crashed`.

This patch adds service readiness notification to support daemons
employing systemd and s6 notification. Complementing the native
Finit readiness support using PID files that exist already.
The two have slightly different ways of implementing readiness:
- https://www.freedesktop.org/software/systemd/man/sd_notify.html
- https://skarnet.org/software/s6/notifywhenup.html
Finit now provides both a NOTIFY_SOCKET environemnt variable, for
systemd, and a way to start s6 daemons with a descriptor argument.
For details on the syntax, see the `service` documentation.

This change allows endless restarts, similar to `respawn` but honors
`restart_sec`. There is no upper limit on the number of times Finit
tries to restart a crashing service. Same as `restart:-1`

When logged in from sulogin we cannot send IPC to Finit, not even
signals, to delegate reboot. For usability, attempt to tell reboot that
it's in sulogin mode -- provided the bundled sulogin is used -- to let
reboot trigger over to forced reboot.
We cannot do much about initctl, just document this as a limitation.

- Add `type:forking` service option to trigger guessing pidfile to
watch for, instead of `pid:!foo` option, which is not intuitive.
This option may likely also survive into the new file format :)
- Update docs and add examples
- Update start-stop-serv.sh test case with this new variant

- Check if watchdogd *and* `WDT_DEVNODE` exists before registering the
built-in watchdogd at boot
- Update bootstrap.md with this additional constraint
- Update config.md with references to bootstrap and the new constraint
