Why isn't __gmp_extract_double's style OK for mpn_set_d? Is its
conventions not neat enough, or are there efficiency reasons?
I found the conventions of __gmp_extract_double hard to understand. And
I think returning a base 2 exponent is

Personally, I feel a bit easier about adding feature close to release,
than about rewriting code for existing features.
So, maybe we can discuss about adding a new function to the _limbs interface:

Uhm, in tests/mpz/t-limbs.c we test MPZ_ROINIT_N only
