#5817: [with spkg, needs review] Update FLINT to 1.2.5 (latest upstream release)
----------------------+-----------------------------------------------------

Comment(by dmharvey):
The output of {{{change_ring}}} (in the previous example) is not of type
{{{Polynomial_zmod_flint}}} as it should be, it ends up being
{{{Polynomial_generic_dense}}}. The multiplication ff * gg is actually
calling the generic karatsuba code in the Sage library, it's not calling
FLINT or {{{zn_poly}}} as far as I can tell. Each input to
{{{do_karatsuba()}}} is a list containing a single polynomial, instead of
a list of coefficients.
Probably making {{{change_ring}}} return the correct type of object will
fix all this mess. I don't think it has anything to do with FLINT or
{{{zn_poly}}}. Maybe it's a coercion problem.
