mpn_redc_n

[paul zimmermann]

       Hi,

we might use mpn_redc_n in GMP-ECM, depending on tuning results wrt mpn_redc_1,
mpn_redc_2, and other functions.

However, it seems mpn_redc_n uses the inverse convention for the precomputed
inverse (ip[] = 1/mp[] mod R^n instead of -1/mp[] mod R^n for redc_[12]).

Would it be possible to use the same convention?
