Summary:  gnu/java/security/util/Prime.java ignores return value of BigInteger 
methods

Original Submission:  At 4 places in gnu/java/security/util/Prime.java, add is 
called on a BigInteger as though it mutates the BigInteger it is invoked on 
(lines 58, 63, 79 and 125). 

BigInteger is immutable. Thus, methods such as BigInteger.add return a new 
BigInteger, rather than mutating the BigInteger they are applied to.
