This is a major refactor to use the same construct as in the pidfile.so
plugin to parse kernel inotify events for when TTYs are added removed
from the system.

- Align the two implementations in logit.c and utmp-api.c
- Use libite APIs to handle common constructs
- If gzip fails, don't remove rotated-to file
- Don't try gzip if rename fails

Ignore EBUSY errors, the kernel has the ability to automount /dev as
soon as the rootfs has been mounted. This may be added to procfs and
sysfs later, so we make this a general change in fs_init().

- Decleare some return values with (void)fn(), for cases where
we don't care (dropping table headers), or best effor
- Check return value from fgets() and chdir() in some cases that
are valid, i.e., continuing execution is pointless

No point in using rq.data, which could have been modified, instead use
the input argument to the function in the error message.

While skimming through the results of the latest Coverity Scan, I
discovered that that the reset logic of global rlimits was broken.
This it seems to have been since its first introduction in Finit.
We fix this by reading initial rlimits at bootstrap, then for each
reconf, including the first, we seed global rlimits with the initial
ones -- thus resetting between each reconf.

The utmp_set() function allows id==NULL, so default the line to NULL and
avoid parsing empty lines. Which is better code anyway.

Mostly used during development, doesn't really provide any value to the
user at normal runtime. Leave it commented out though so user can do
debug themselves if needed.

- Refactor screen_init()
- use native impl. of TTY probing from pimd project
- check if TIOCWINSZ works
- check if we're running in watch(1), for initctl
- check if ANSI goto(999,999) escape seq. works (invasive)
- fallback to 80x24
- Drop screen_exit()
- Rename screen_init() to get_width(), for now, matching pimd
- Relocate call in main() to banner(), first fn to write to TTY

With the recent changes to the condition handling it has become more and
more evident that the canonical reference for a task/run/service is the
NAME:ID representation. Up until now we've kept the older JOB:ID for
some sort of compatibility fallback.
This patch removes the support to simplify maintenance going forward.

This is quite possibly the ugliest pieces of code in this project.
It is a quick fix to the problem with strtok() to split up the cmd into
cmd + args[]. Without it wordexp() will later get very cranky about
trying to expand `"Partial` strings from commands like this:
/sbin/udhcpc-wrapper.sh -f -S -V "myOS v9.99" -t 8 -T 5 -A 10 -R -p \
/var/run/udhcpc-vlan1.pid -i vlan1 -x hostname:myos-12-34-50 -o \
-O 1 -O 3 -O 6 -O 7 -O 12 -O 15 -O 42 -O 121 -a
Yes really.
It's an obviously far from perfect solution. One might even start to
question why we have an args[64[64] per svc_t and not just a cmd + arg?
Well, there's a lot of improvement potential here, let's talk!

If mg doesn't exist, command doesn't evaluate the second argument (vi),
so we need to use `... || command -v vi` instead. Found during demo,
because why not.
