This fixes the regression in the tests, which runs in a very stripped
down world without tmpfiles.d etc.

This adds a new function conf_save_service() replacing service_register() for
plugins and bundled services like watchdogd, keventd, runparts, etc.
The benefits to this change are several:
- Plugin/Bundled services no longer risk starting before udev or other
critical services/task have started
- Definitions can be overridden by an administrator (see docs)
- Increases visibility (user: where are all these services coming from?)
Previously the origin (file the service was loaded from) was NULL.
- Adds another level of extensibility to Finit
The most notable change is that dbus is no longer started before udevd.

The system/10-hotplug.conf needs to index its calls to udevadm for all
calls to udevadm, not just the trigger calls. Otherwise the first
udevadm is overloaded with all subseequent (unindexed) udevamd stanzas.
Also, make sure all udevadm calls to settle/reload are hidden.

The if: statement, introduced in v4.4, allows for discarding run/task/services
that depend on other services, based on that service's name, or condition.
Discarding in this context means unloading from the configuration.
At runtime, however, it has proven quite useful to be able to conditionally
qualify a run/task/service based on a condition. Consider this example from
the Infix operating system:
run name:startup log:prio:user.notice \
[S] <pid/sysrepo> confd -b --load startup-config -- Loading startup-config
run name:failure log:prio:user.critical if:<usr/fail-startup> \
[S] <pid/sysrepo> confd --load failure-config -- Loading failure-config
The two run statements reside in the same .conf file so Finit runs them in true
sequence. If loading the file `startup-config` fails confd sets the condition
usr/fail-startup, thus allowing the next run statement to load `failure-config`.
Notice the difference between <pid/sysrepo> condition and if:<usr/fail-startup>.
The former is a condition for starting and the latter is a condition to check if
a run/task/service is qualified to even be considerered. The best comparison is
with the [runlevel] option, it too is used to qualify.

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.

No more changes are expected after -rc3. Will be used for testing in
Infix and br2-ext-finit before the final v4.5 GA.

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.

As pointed out in #366, the configure options --enable-fastboot and
--enable-fsckfix should just alter the default values of the two fsck
command line options.
This commit simplifies the code and makes it possible to override using
the command line regardless of the two build options.
Finally, add the two command line options to doc/cmdline.md

We use LOG_CONS to ensure log messages reach the operator, but since
watchdogd starts very early this means non-critical messages like the
initial greeting leaks to console because syslogd has not yet started.

With non-standard paths, e.g., when running `make distcheck`, the
absolute path to some commands become ridiculously long. However,
this has been a recurring issue for some users in the past, so it
is time to increase the capabilibieies of Finit to cover this.
Yes, a better way is probably to allocate all these strings when they
are used, but that would require a redesign of the initctl API and
likely cause a lot of regressions before everything has stabilized.

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.

In issue #357 there's a proposal for optionally allowing /bin/login, but
after intense discussions we've agreed that would be opening up for all
sorts of potential (security) issues.
it's better to keep things as-is but with the added twist of supporting
a custom user at configure time, e.g., 'admin'.

Non-trivial systems, like Infix[1], require more than one lap around the
track to warm up. This is a follow-up to issue #362, commit 4701ede, in
fixing an obvious oversight in the new sm_check_bootstrap() work. While
there are still outstanding bootstrap tasks or services that have not
yet started, we must reschedule the worker.

Drop complete() logic, waiting for run tasks to finish, from the
service_start() funciton to the general service_monitor(). This
refactor frees up the main loop and allows us to answer any API
calls from initctl even from the run task itself.
