For ease of use, allow short forms of commands, like:
initctl h
initctl c d
initctl l
Also, default to show conditions if no argument to cond is given.

We need the name client.c for the client side of api.c, so let's rename
the client to its traditional name.

Previously UDP packets were never dropped and if a request came
from a not valid interface inetd got stuck in an inifinite
loop looking at the same packet every time and not dropping it.

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.

This patch implements support for calling run/task jobs on the built-in
`HOOK_*` points in Finit. To map each HOOK point to a condition a new
classification was made, as shown in plugin.h and in the example below.
task <hook/mount/root> /sbin/attachubi.sh # run in parallel with other tasks/services
run <hook/net/up> /sbin/dosomething.sh # run in sequence with other commands
Please note, only rudimentary tested.

Make svc state transition to RUNNING *before* service_start(), because
in that function we may call service_step() as well, which would start
the svc again (since it was still in READY).
Signed-off-by: Joachim Nilsson <troglobit@gmail.com>
Only run HOOK_SVC_START on successful start, and *after* having printed
the result of the started service, otherwise any print-outs from plugins
or tasks we start may overwrite the started service's progress.

Don't really see the point of this code anymore, was possibly an issue

If you have lots of service/run/tasks using the same cmd it's impossible
to tell them apart in debug mode. This patch logs description as well
as cmd to improve on this situation a bit.

This patch adds a 'once' counter to the svc_t for run/task jobs. This
counter is incremented when Finit calls service_start() and is reset on
runlevel changes.
Also, at the end of a runlevel each run/task have their state reset to
SVC_HALTED_STATE so they can be launched again for the new runlevel, if
so declared.

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 fixes a rather nasty bug in the SIGTERM+SIGKILL logic
employed by Finit when stopping tasks, e.g. at a runlevel change.
When a process terminates, after Finit having sent it SIGTERM, and the
SIGKILL timer expires *before* the timer has been cancelled, then the
timer callback would cause kill(0, SIGKILL).

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.

If the speed argument to the `tty` stanza is invalid we should not
default to some other random speed. Instead, leave the line speed
as-is, like we do when starting an external getty.

This patch relocates the speed parser so that exec.c can set the TTY
speed properly as soon as possible. For external getty we make sure
to not touch the TTY speed.

This patch makes the Finit built-in getty behave a bit more like other
getty implementations. We now not only disable ISIG but also VEOF and
VINTR when prearing the TTY for the getty (built-in or external).
Like before, it is up to the getty process to leave the TTY in a
usable state to /bin/login, so we also move the stty() call to
just before calling /bin/login in getty.c
