I have a new patch to change the Selmer group test, since the signs can change randomly. Needs review.

    v43 v50  
    55The data used by PARI to compute whether or not an element is a norm can be computed once for each extension `L/K`. The function `pari_rnfnorm_data` computes exactly this, and hopefully in a later version its result can be passed to `is_norm` to avoid recomputing it each time in the case that `K != QQ`. If `K` is `QQ`, there is no need to save any such data -- the only data needed is that of `K.pari_bnf()`, which is used instead, and is already cached by `K`.
