Totally remove the supposedly 'faster' variant in
BN_mod_mul_montgomery, which calls bn_sqr_recursive without much preparation. bn_sqr_recursive requires the length of its argument to be a power of 2, which is not always the case here. There's no reason for not using BN_sqr -- if a simpler approach to squaring made sense, then why not change BN_sqr? (Using BN_sqr should also speed up DH where g is chosen such that it becomes small [e.g., 2] when converted to Montgomery representation.) Case closed :-)
