This change expands the readiness notification system in Finit with the
native 'pid' style, which will remain the default readiness in Finit 4.x
For systems that want to transition to Finit 5.x early, a global option
to set 'readiness none' in /etc/finit.conf, has been added. This change
the service default notification mode to 'notify:none', which can also
be set by Finit 4.x ('readiness pid') for select services.
Fixes#386.

This odd little feature makes it possible to declare run/tasks with a
condition that does not block Finit transitioning from bootstrap to the
next runlevel.

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.

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.

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

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.

Instead of the revert in c9fe9afa, we restore HOOK_BASFFS_UP to its
proper place at the end of fs_mount_all(). For this to not cause any
regressions we add a new hook, HOOK_SVC_PLUGIN, and update all plugins
that call service_register() to run at the new hook.
This will cause regressions for external 3rd party plugins that rely on
HOOK_BASEFS_UP to be called at its previous postion. Nevertheless, this
is the proper fix to the problem.

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.

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.

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 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 change adds support for running hook scripts at two new hook points
during the shutdown process:
- HOOK_SVC_DN: after all services and non-reserved processes have been
killed (and collected)
- HOOK_SYS_DN: after all file systems have been unmounted, *just prior*
to Finit calling reboot() to shut down or reboot the system
See doc/plugins.md for details and an example.
