Implement watchdog for the boards supported by EMT.

HAL is provided by Energia.app/Contents/Resources/Java/hardware/emt/ti/drivers/Watchdog.h.

Unlike the other RTOS elements proved in the Galaxia library, each platform has watchdog-related specifics under the Energia.app/Contents/Resources/Java/hardware/emt/ti/drivers/watchdog folder.

Copied from original issue: energia/Energia#782

I think we should stick this into a library. MSP430 currently (ab)uses the watchdog timer as an interval timer to keep track of millis/micros.

That would be a great idea. For EMT-based projects, it is easy. The question is more about non-EMT projects.

See the example and discussion for the CC3200 at http://forum.43oh.com/topic/9346-cc3200-watchdog/

Not sure it works on the MSP432.

The only caveat is the WDT_IF_DeInit() function doesn't seem to deactivate the watchdog.
