David Benjamin 5148345282 BN_mod_exp_mont_consttime: check for zero modulus. 
Don't dereference |d| when |top| is zero. Also test that various BIGNUM
methods behave correctly on zero/even inputs.

(Imported from upstream's cf633fa00244e39eea2f2c0b623f7d5bbefa904e.)

We already had the BN_div and BN_MONT_CTX_set tests, but align them with
upstream's for consistency.
