Form a tuple of tripwire values

This is intended to be used to create a tuple of PBufTrip values both before and after an operation. The tuples can then be compared to see whether there was any change.

let before = tripwire!(p1, p2, p3, p4);
// some operation on p1/p2/p3/p4 ...
let after = tripwire!(p1, p2, p3, p4);
let activity = before != after;
