When performing an `initctl reload` with one (unchanged) service
depending on, e.g. `net/iface/lo`, its condition will not be set
to ON by the pidfile plugin unless the netlink plugin hook runs
first.
Example:
service <net/iface/lo> /sbin/dropbear ...
Which provides the <svc/sbin/dropbear> condition, will not be
set by pidfile.so during `initctl reload` because dropbear is
still SIGSTP:ed waiting for <net/iface/lo>.

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.

Before we call screen_init(), which in turn calls libite:initscr(),
which in turn does a lot of tcgetattr() and termios to STDOUT to figure
out the size, we need to check that we're not backgrounded, or don't
actually have a TTY. Problem reported by @wkz

This patch adds support for a new TTY device keyword `@console` which
auto-detects the system console by reading the SysFS file:
/sys/class/tty/console/active
Embedded systems with one of /dev/ttyAMA0, /tty/ttyMXC0 or the original
/dev/ttyS0, as their active serial console can now instead use a single
line to /etc/finit.d/getty.conf to start the built-in getty on the same
TTY as the kernel already runs on:
tty [12345789] @console 115200 noclear
With no TTY defined Finit will either do nothing (default), or start a
fallback shell if enabled in the configure script.

Disable INTR, QUIT, SUSP, and DSUSP while handing over to getty. It is
up to the getty process to allow ISIG again.
This patch is due to the differences in control line setup between ARM,
x86/x86_64, and most notably PPC. PPC in particular seem to have ISIG
set by default from the kernel.
Without this patch pressing Ctrl-C before getty is started will lead to
Finit receiving SIGINT and defaulting to a reboot, as introduced in the
BusyBox init signal adoption in eeb59eb.

In GCC 7 the -Wall infers the new -Wformat-truncation which finds
problems with string truncation in functions like snprintf().
This patch suppresses the warning by allowing only a subset of the
parent inetd service description to be copied to the child connection.

This patch fixes a possibly problem in path name creation which,
combined with the scandir() function, might cause loss of .conf
files, failure to call run-parts properly, and kill services at
shutdown.

In GCC 7 the -Wall infers the new -Wformat-truncation which finds

This patch fixes a problem in condition parsing for very long
PID filenames which might be truncated in internal buffers
causing a mismatch in Finit condition tracking.

In GCC 7 the -Wextra infers the new -Wimplicit-fallthrough which can be
suppressed by adding a simple comment
/* fallthrough */
Which we had, but was too verbose (and misspelled) for GCC to notice.

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.

Finit has long since supported an @user:group syntax to services, tasks,
and run stanzas. Setting UID was implemented at that time, but setting
GID never was. This patch fixes that oversight.
