This patch introduces a new option to initctl; -b, --batch skips
screen_init(), which might otherwise leak ANSI screen resize codes
to the console.

When an UDP inetd connection terminates we must make sure to unblock the
parent, which is (currently) blocked during the transaction.
This patch is a fix to a regression introduced in 2c904b5, for v3.1

Starting in debug mode and disabling debug at runtime did not exhibit
the same behavior as if starting in normal mode and toggling debug mode
at runtime. This patch adds toggling of silent mode (progress output)
to runtime debug toggling.

The screen_init() call for each print() & C:o caused serious screen
artefacts in debug mode. This patch reworks f858d94 to only re-init
screen when toggling debug.
Also, avoid screen_init() completely if started in debug mode.

- Don't warn of missing PID, even if only _d(), perfectly normal
- Allow stopping restart timer of non-services (e.g. task/run)
- Allow stopping services with no PID rn, i.e. stop libuEv timer

On `initctl reload` we reassert conditions, i.e. bring each still viable
condition back in sync with the new reconf generation. This patch fixes
an assumption in the reassert() callback that caused the following nasty
transformation:
/run/finit/cond/net/lo/up --> /run/finit/cond/lo/up
The transformation was caused by the reassert() code assuming a /var/run
prefix rather than /run. We must check the actual runpath, or like this
patch does, use a path neutral way to find the base condition string.

The cond_init() function is called before the bootmisc.so plugin has
run. It is responsble for setting up the /var/run symlink to /run on
systems with the new layout. Therefore we must wrap COND_PATH with
pid_runpath() to create the correct runtime path.

Finit tries to restart crashing services. If a service is removed
before Finit has given up restarting it, then the background timer
responsible the restart may dereference a free():d svc_t.
Hence, make sure to properly stop (and step) a service and its timer
callbacks in service_unregister() before calling svc_del().

In service_stop() we call svc_del() which, as of Finit v3.1, free():s
the svc_t, so we don't want any lingering restart timers to wake up
after free() and start dereferencing the svc_t.

To improve debug possibilities at shutdown, keep gdbserver running even
during shutdown.
Note: The gdbserver service runlevels must be sth like [123456789] for
this to work in the first place.

On most modern Linux systems /run is a tmpfs that replaces /var/run.
The latter is set up as a symlink to /run by the bootmisc.so plugin.
However, Finit conditions rely on the /var/run/finit/cond prefix, which
does not exist until bootmisc.so has run, which is *after* `mount -a`
has run. Therefore, to have working conditions before we run `mount -a`
we must normalize the path constructed by cond_path() to use either the
/run or /var/run (default) prefix.

This gives the operator a way to add a post-mount script, e.g. to peform
a 2nd stage mount or mount preparations, before the bootmisc.so plugin
and others run in hook/mount/all

The job:id field can now be used to display job:INET_PORT_NUMBER, e.g.
100:16161 for job 100 localhost SNMP port 16161.
The service name field has been reduced from 20 --> 16 bytes since the
full path has been reduced to display the basename.

An external plugin to set up /etc can use HOOK_BASEFS_UP, but the Finit
conf_monitor() must then be called *after* not before that hook, or the
inotify watchers will listen on the wrong inode.

The SVC_RECONF, SVC_LOST, SVC_START, and RUNLEVEL_CHANGE hooks are not
one-shot, they are also not regular conditions since there exist no
mechanism to reset them from flux.
One idea was to turn them into actions, but the lost + start hooks need
to be called multiple times per trigger, e.g. `initctl reload`, which
turned out to be non-trivial to implement right now.
Therefore, for (at least) the Finit v3.1 release these conditions have
been disabled ("nop") and ignored by Finit. Only actual C-style plugins
will be called.
