Brian Smith 448fa42779 Deprecate |BN_mod_exp2_mont| and simplify its implementation. 
This function is only really useful for DSA signature verification,
which is something that isn't performance-sensitive. Replace its
optimized implementation with a naïve implementation that's much
simpler.

Note that it would be simpler to use |BN_mod_mul| in the new
implementation; |BN_mod_mul_montgomery| is used instead only to be
consistent with other work being done to replace uses of non-Montgomery
modular reduction with Montgomery modular reduction.
