This patch adds support for watchdogd, a watchdog daemon with built-in
process supervisor[1] as well as support for monitoring memory & file
descriptor leaks, and CPU load average. When a monitored resource
reaches a high watermark, a warning message is logged and when critical
level is reached, the cause is saved and the system is rebooted. On
reboot the reset cause can be retrieved to help locate the culprit.
Support for SysV init script in this patch, and systemd unit file is
installed from the one bundled with the package. Both files supoort
additional command line options in /etc/default/watchdogd.
The Config.in is slightly big, but allows for disabling or adjusting
the poll interval for each resource monitor.
