Fixes #546
PowerMod(p/q, b, m)andPowerModList(p/q, s, m): the base is read asp * q^-1 mod m; a base with no inverse (PowerMod(1/2, 2, 4)) stays unevaluated. Works with a negative or rational exponent.typehandlers saylist<integer>/list<list<integer>>when an operand is a list andinteger/list<integer>otherwise.ChineseRemainder(residues, moduli, d): the smallest solutionx >= d.lazy: true, so.N()leaves the exact operands alone.Existing tests that pin old behavior changed: none. Compiled code: the heads have no lowering, so the new forms decline as the old ones do.
