computes absolute violation for auxvar relation in an expression w.r.t. auxiliary variables
Assume the expression is f(w), where w are auxiliary variables that were introduced by some nlhdlr. Assume that f(w) is associated with auxiliary variable z.
If there are negative locks, then returns the violation of z ≤ f(w) and sets violover to TRUE.
If there are positive locks, then returns the violation of z ≥ f(w) and sets violunder to TRUE.
Of course, if there both negative and positive locks, then return the violation of z = f(w).
If the given value of f(w) is SCIP_INVALID, then viol is set to SCIPinfinity() and
both violover and violunder are set to TRUE.
