e0f18128bf task_wdt: fix silent init failures 
The task_wdt_init() API can fail to install a timeout for the fallback
hardware WDT (hw_wdt) without returning an error code.  This patch
enables task_wdt_init() to return the hw_wdt install timeout error code
if the hw_wdt install timeout fails.

1aaf508bde task_wdt: add task-level watchdog subsystem 
This new subsystem can be used to supervise individual threads. It
is based on a regularly updated kernel timer, whose ISR is never
actually called in regular system operation.

An existing hardware watchdog can be used as an optional fallback if
the task watchdog itself gets stuck.
