Convert openssl code not to assume the deprecated form of BN_zero().
Remove certain redundant BN_zero() initialisations, because BN_CTX_get(), BN_init(), [etc] already initialise to zero. Correct error checking in bn_sqr.c, and be less wishy-wash about how/why the result's 'top' value is set (note also, 'max' is always > 0 at this point).
