This patch allows scripts to have more control over the software WDT. If an instance of machine.WDT is created then the underlying OS is prevented from feeding the software WDT, and it is up to the user script to feed it instead via WDT.feed(). The timeout for this WDT is currently fixed and will be between 1.6 and 3.2 seconds.
