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 commit replaces the `mdev -s` call to populate the device tree with
the "new" `mdev -df` daemon mode, introduced in BusyBox 1.31.0, 2019.
In daemon mode mdev listens to kernel uevents, replacing the hotplug use
of mdev. After creating the netlink socket, 'mdev -df' performs the same
initial scan as 'mdev -s' did.
To perform device (re)discovery, module loading and setup, including any
firmware loading, a coldplug operation is typically required. This is
done by the new /libexec/finit/coldplug script, by Alexander Zangerl.
Unlike 'mdevadm settle', mdev does not offer any mechanism to detect when
the discovery operation is done: on slower systems the triggering side,
the coldplug script, often completes quite a bit earlier than mdev's
uevent processing. I.e., depending on <run/coldplug/success> is not an
indicator of all devices having been (re)discovered and fully set up.

On some systems udev may very well take more than five seconds to complete.
Probing modules, loading firmware, etc. Note, the timeout only sets the
maximum wait time.

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 user may have their own setup of things, by default we should not
cause unnecessary warnings in syslog.

This is the first example of the just minted advanced stanza syntax with
if-statements, conflict handling, and nowarn flags.
