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.

This patch adds support for restarting the API socket on SIGHUP, similar
to how SysV init and systemd use SIGUSR1 to restart their FIFO or D-Bus.

On shutdown/reboot, send SIGPR as a heads-up to watchdogd that the
system is going down. All file systems are about to be unmounted.
It's just about the last process left running in the system, so we
give it two seconds to complete its work before we continue.
When everything has been unmounted and we're ready to call reboot(),
we send SIGTERM to the registered watchdog, to give ti the chance to
let the WDT reset the system.

When alibuEv event watcher callback has `UEV_ERROR` in the events mask
we must handle the error. Unfortunately, in most cases there is not
much we can do but ignore it or log the error.

In GCC 7 the -Wall infers the new -Wformat-truncation which finds
problems with string truncation in functions like snprintf().
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 case the kernel is incapable of handling a reboot,
power-off, or halt request we want to be able to let
the user perform some basic diagnose of the system.
The existing debug messages are good enough, and use
the correct grammar form, to be enabled always.

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.
For reference, see issue #69 and PRs #70 and #72.
