rootofunity: Use a better approximation of the lost bits.rootofunity
* src/rootofunity.c [mpc_rootofunity]: Drop the absolute bound for the
number of lost bits in favour of a bound depending on the exponents
of the result.
* tests/rootofunity.dat: Add examples with large n, that is, a result
close to the axes.
