Joachim Wiberg 099672fabb configure: change --enable-redirect -> --disable-redirect
This changes the default to redirect output from run/task/services to
/dev/null.  Use --disable-redirect to get the old pre v4.0 behavior.

Joachim Wiberg 860515a716 contrib: load softdog module on Alpine/Void Linux for finit-watchdog
We need at least the softdog watchdog driver loaded for proper watchdog
reset at reboot.  This can safely be replaced with a hardware specific
module that provides /dev/watchdog ... without one Finit will try to
restart the built-in finit-watchdog service 10 times to no avail.

Joachim Wiberg 06e456384c watchdog: Enable --with-watchdog[=DEV] and improve log messages
This patch changes the configure option to enable the built-in watchdog
from --enable-watchdog to --with-watchdog[=DEV].  This is the convention
for features that take arguments.

Also, improve log messages to aid debugging when finit-watchdogd does
not start properly.  This means flushing logs to syslogd with closelog()

Joachim Wiberg dd437bf0a5 Follow-up to 18ab7d3: restore start of built-in watchdogd
This patch restores the start of the built-in/bundled watchdogd.  It is
tracked in the `wdog` variable and handled as an exception at shutdown.

This is also a follow-up to 7b74c99, ensuring that we only kill/stop the
built-in watchdog, not any external.  External ones can register to be
the controlling watchdogd in the system -- Finit is not the arbiter for
singletons, this is up to the system engineer.

Joachim Wiberg ba858743e5 Fix #129: add pre:script and post:script action support
This patch updates the service state machine with two new states: SETUP
and CLEANUP.  If an executable pre:/path/to/script is defined for a
service, it is called every time the task goes to READY state.  If an
executable post:/path/to/script is defined for a service, it is called
when the task goes to HALTED state.

Each of these two scripts default to a three (3) second execution time
before they are SIGKILLed.  This can be adjusted with the `kill:SEC`
option for the service.  There are no execution guarantees, nor are
there any way of detecting if the script was killed before completion or
not -- except for running Finit in debug mode and inspecting the result
printed by system_monitor().

Note: the post:script MUST be idempotent since transitions between READY
      and HALTED can take place any number of times before a task goes
      to its RUNNING state.

Joachim Wiberg be343a3b34 plugins: call bootmisc:bootclean() in HOOK_MOUNT_POST
Before this patch bootclean() ran first in setup() which caused to to
remove the entire /var/run/finit directory, and other files as well,
created earlier.  Only possible fix is to split clean and setup in
two and make sure to call clean as soon as we've mounted everything.

Note: this introduces a new behavior, and anyone hooking into the
      same point to do good-stuff(tm) may be affected by this.

Joachim Wiberg c0368d2b16 Refactor fallback shell handling, run as regular service
This patch re-enables the fallback shell handling after the big TTY
refactor.  We do this by allowing the fallback shell to run as a
regular service.

Note: this also adds the "hidden" support for 'notty' option for
      tty configurations stanzas.  This is just to pick up from
      where the kernel left us, reusing stdin + stdout.
