The BusyBox hwclock is really bad at handling, or rather displaying,
errors properly. When the kernel signals EINVAL, or ENOENT, it just
shows that message on stderr.
This patch implements proper RTC load/store at boot/halt with quite
some improved error handling suitable for embedded systems.

Similar to how systemd creates cgroups for all services, for purposes of
tracking, Finit now does the same. We also mount all available cgroups
in the /sys/fs/cgroup namespace.
This patch adds support for grouping processes in logical cgroups, like
systemd, and an `initctl ps` command to list the hieararchy.

Allows the service/task name derived from the binary to be
overridden with a custom name.
Example:
service name:dhcpd [2] /usr/sbin/udhcpd -f -- DHCP Server

This patch is an attempt to address an issue with runparts scripts found
by Magnus Malm, @magnusmalm. Any script in:
runparts /foo/bar.d/
were required to have the #!/bin/sh she-bang, otherwise Finit would not
start them. He tested with the standard run-parts tool, which had no
such restrictions.
The patch not only makes sure to start scripts using `/bin/sh -c`

We can now rely on service_step() to continue stepping run/taks/services
until no more state transitions are made.

Instead of changing the API of service_step(), and relying on all the
different callers to step again, we can schedule another event to do
this for us.
In addition to handling the cond_update() case this also handles all
other callers of service_step(). Ensuring that nested conditions do
trigger changes.
Also, reverting dddd45e fixes a minor regression in service_monitor()
which caused it to not clean up collected bootstrap tasks.

In cases where you have multiple events pending in the cache and some
event may cause later ones, already sent by the kernel to userspace,
to be deleted the pointer returned to the event loop for this later
event may be deleted.
There are two ways around this (accessing deleted memory); 1) use this
function to initialize your event loop and set maxevents to 1, 2) use a
free list in you application that you garbage collect at intervals
relevant to your application.

We allow all run/task/services to complete before changing runlevel.
This means stepping them all while we wait for their completion, since
services may depend on each other.
