Add a watchdog counter to API shared memory

Add a watchdog counter or something similar into the shared memory header. If the counter fails to update, initiate UFO. If PIBufSS crashes, data loss can occur.  implement something that allows UniInt to know that the Buffer Subsystem is not responding and initiate failover if available. This was previously enhancement 119481.

    The same behaviour can also be observed with PI buffer server running on UNIX. If the buffer process is forceably stopped on the primary interface node, this will not trigger interface failover and the primary interface will be unable to send data to PI. Data loss can occur until the situation is manually resolved.
