The SysV API compatibility layer gives too little value to be worth
the effort of maintaining it. Users are encouraged to use the
`initctl` tool instead.

Slight reshuffle of columns so status and condition listings are more
similar. Also, calculate and adjust necessary column widths.

With the recent change in the condition handling we've decided to put
the (name,id) tuple in focus for everything Finit.
This patch changes from job:id in the status listing to name:id instead.
In verbose mode we change to show the job:id and the command + args.

This patch removes the built-in inetd support from Finit. We recommend
using an external inetd instead, e.g. xinetd.
If you liked the feature set our inetd provided; filtering per interface
and port redirection, then please let us know or use the code in this
patch (MIT licensed) to recreate it. We are open to reintroducing it,
but then as a stand-alone daemon like the bundled watchdogd and getty.
So long for now, old friend.

Change service conditions from the non-obvious <svc/path/to/foo> to
<pid/foo:id>, utilizing the unique name of the service instead of the
weird composition of paths from /run and PID file names. Hopefully
making it more clear that one service's pidfile is another service's
`<pid/foo>` condition.
Note: this is an incompatible change to the condition system!
The Finit major version will be stepped to indicate this.

From, e.g.,
Starting foo:, PID: 123
to
Starting foo[123]
or, when an ID has been given
Starting foo:id[123]

This fixes the problem with lingering Makefile's in /etc/finit.d/ on the
target systems. We also get the new enabled services properly set up.

The initctl tool's enable/disable command can then be used to manage
these services after install. This is what most users expect.

Planned changes will directly change the behavior of conditions, and
instead of having to implement compatibility wrappers and further
complicate the code, we've taken the decision to go for v4 directly.
This allows us to also rip out the complex inetd support.

The <svc/foo> condition was created to synchronize starting services,
hence the abbreviation. Example: the Quagga ripd needs to start after
the zebra daemon to ensure its UNIX domain socket is active, otherwise
events may be lost.
However, considering that synchronization was implemented with UNIX PID
files, e.g. waiting for /var/run/quagga/zebra.pid to be created, the
condition abbreviation name <svc/foo> was hard to understand by most
newcomers to Finit. To make matters worse, a new feature to track or
even create PID files for services that don't create one themselves,
using the syntax 'pid:/path/to/foo.pid' was added.
Connecting the dots between these wasn't obvious.
This patch renames service conditions pid conditions and also adds
a compatibility wrapper to the Finit .conf parser. Any condition
given in old .conf files with 'svc/' prefix are internally renamed
'pid/', along with a LOG_INFO notice in syslog.

The recently updated pidfile plugin now also watches the subdirectories
in /var/run, but for that to work it must witness the creation of these
subdirectories. The bootmisc plugin creates several, e.g., /run/quagga/
in which PID files like zebra.pid are created.

- Absolut paths are only necessary in case of ambiguities
- Without absulute paths conditions are shorter, e.g. <svc/syslogd>
- Drop <net/lo/up> condition for SSH daemons, not necessary

As documented in the kernel docs and systemd[1], the default system
console is the first listed in /sys/class/tty/console/active, which
is the reverse order of console= given on the kernel cmdline.
Some distros don't have console= on their default command line in
their bootloader, e.g. Alpine Linux, some multiple, e.g Buildroot.
Instead of relying on the value given at configure time we probe
sysfs and open all (at most three) consoles listed. This way we
at least get the default console for our progress output.
- drop old --with-console from configure script
- drop /proc/cmdline fishing in favor of sysfs
- replace CONSOLE from configure with new console()

- Changing the GNU defaults is messy. The best way is to leave them

From the start, the output from the 'list' command has been different
from the output of the 'show' command. No longer.
Also, drop the 'AVAILABLE', 'ENABLED', and 'STATIC' prefixes. They were
a bit screamy and superfluous. 'STATIC' wasn't even a good name for the
locally administered ones.

All Debian based distros are moving towards a /etc/network/interfaces.d/
world. Adding support for that is too complex, so we're reverting back
to calling 'ifup -a' or 'ifdown -a'. We still guard this by checking
both for 'ifup' and the existence of /etc/network/interfaces (which in
the new world only contains a line to source per-interface files).
By popular demand, this patch also changes to bring up/down networking
in the background. Useful for embedded system bringup and containers.

Some targets, like Raspberry Pi, have both serial and HDMI console
enabled. Depending on the order of arguments on the kernel cmdline
either one were selected the default 'stderr', which finit used.
This patch adds support for parsing the console= string(s) and
opening multiple outputs for system startup/progress. In the
end, however, a getty still needs to be started on each of the
consoles to use.

We need /proc for rs_remount_root() and conf_parse_cmdline(), /dev for
early multi-console support, and /sys for the cgroups support. All of
these may be in the system /etc/fstab, which fs_mount() later remounts.

Many systems have a very verbose kernel by default. This patch calls
`klogctl(SYSLOG_ACTION_CONSOLE_OFF, NULL, 0)`, which is sysklogd also
calls but later when it starts emptying /dev/kmsg.
We do this to get an undisturbed console while starting up.

This seems to be inline with Busybox init, SysV init and, according
to the comments in code, the intended behaviour of Finit.
The effect is that `SIGPWR` will lead to Finit issuing the syscall `reboot`
with `cmd` parameter set to `RB_POWER_OFF` (rather than `RB_AUTOBOOT`), which
in turn will lead to a halt rather than a reboot.
The effect of the above inside a PID namespace other than the initial PID
namespace is that `wait` inside the parent of Finit will report that Finit was
killed with a `SIGINT` signal rather than `SIGHUP`.
