This patch moves the networking bit to the latter part of bootstrap,
called finalize(), in favor of starting the event loop earlier.

This change removes a long standing kernel requirement and architectural
mishap in the design of Finit v1. It is no longer necessary to include
CONFIG_SYSVIPC in the kernel to use Finit and its command line tool
initctl. It is also no longer possible to connect to the internals of
PID 1 using shmat(), the initctl tool has already been updated to use
the domain socket API.

This patch fixes the problem with run/task jobs with conditions, run at
runlevel S (bootstrap), not being given enough time to actually start
and run even once.
The new svc counter 'once' is now inspected before transitioning away
from runlevel S to the configured runlevel. A global (currently hard
coded) timeout of 10 sec is given to all run/tasks.
As a spin-off, this patch starts up the event loop much earlier than
before. Meaning the initial runlevel change at boot is now done in
a finalize() callback when all run/tasks have completed, or when the
global timeout has expired. Starting the event loop earlier gives us
the possibility to rely on the pidfile plugin to provide our run/tasks
with the conditions necessary to start.
TODO: What remains is to add similar handling to all runlevel
transitions, not just the initial one at boot.

Don't really see the point of this code anymore, was possibly an issue
before we refactored the logging subsystem. Comment out for now, and
remove later.

Systems running OverlayFS, or similar, on /etc may have new/modified
.conf files in /etc/finit.d. This patch makes sure to reload them
after `mount -a` has run so any configured bootstrap tasks and the
new hook callback scripts may run as expected.

This patch extends the existing rlimit implementation to support setting
limits per service, run/task, inetd, and tty.
Use rlimit in /etc/finit.conf to change the global setting, which is
then inherited to each /etc/finit.d/*.conf. For each .conf file the
rlimit is reinitialized to the global finit.conf settings.
Also, add `unlimited` keyword, to replace the now deprecated `infinity`
keyword. The latter is however kept, for compatibility with previous
releases, for the foreseeable future.

This patch not only greatly simplifies the registration of the built-in
watchdog daemon, it also fixes a nasty race condition with an external
watchdog daemon. The INIT_CMD_WDOG_HELLO could reach finit in reversed
order, leading to the built-in daemon shutting down, but finit killing
the just registered external daemon.

Most Linux distributions, embedded or otherwise, do not need this
and only confuses the user of an OS with Finit.

All this code did was trigger prctl() to set process name to "console",
which you could use as a simple means of figuring out if a process was
started from the system console.
There are other ways to do this, which Finit should not be involved in.

In commit 34a1524 the start of udevd was refactored to allow it to be a
properly monitored service caused systems using eudev to malfunction.
This patch reverts part of that commit and adds a workaround found when
trying to reproduce issue #82 on Void Linux:
- Start a temporary udevd in the background
- Call udevadm to trigger bringup of all subsystems and devices
- Wait for everything to settle
- Tell temporary udevd to exit (new)
In the world of `mdev` this song and dance act is not required.

This patch, similar to the work done in the d-bus plugin, converts the
udevd service from a non-monitored run_interactive() task that forks
itself into the background, to a proper Finit monitored service.

It is strongly recommended to instead use the service stanza to start
XDM/GDM, or use startx after a regular login.
Note: the `user NAME` setting was always reserved for use with startx

The emergency shell is just a Finit debug mode. This patch adresses a
concern from GitHub issue #76, with zombie processes in this mode.
Emergency shell could be further improved, e.g. informing the real Finit
process of each collected child (zombie) to be restarted if needed.

This patch moves the plugin loader much earlier, making it possible to
provide a custom banner/logo in a plugin.
To facilitate this move we need to also move banner later and parsing
of the kernel cmdline earlier, right after mouting /proc.

This patch changes the traditional look of the Finit boot sequence.
Now we stick to the screen width probed by screen_init(), or max
132 chars.
Also, some minor cleanup of the currently unused print_timestamp()
method used by printv() when showing [ OK ] or [FAIL] of services
at boot.

Since at least a44daf2 both run() and run_interactive() can access all
system tools in _PATH_STDPATH. A system that uses non-standard paths,
e.g. /system/bin and /apps/bin, should update _PATH_STDPATH.

This patch implemements a new feature of libite v1.9.1, whichp(), which

This patch is a follow-up to 1f1c2e0 which introduced the new semantics
for the very confusing quiet and silent modes.
The initial idea was to loosely follow the kernel cmdline 'quiet' option
and as a working concept this was good. The resulting code, however,
became unnecessarily complex and the configure options impossible to
explain.
With this patch the quiet mode, and thus the --disable-quiet configure
option, is removed. Finit now defaults to a sane behavior: services are
shown only at startup. The --enable-silent option works like it did
before, silencing everything.

Check first ifup exists before using it since
this is really something only exits on some
distros an in different ways. Debian/Ubunu has
an package for this while others have it in the
initscripts package(s) , meaning the file can be
around even without the prog.

This should allow us to run 'prog' without
absolute paths. Eg:
run("/bin/foo"); -> run("foo");
However we still need absolute PATH for
checking since fexist() need full path right now.
