Can I also request fmpz_poly_evaluate_mod?

I posted a patch implementing this here, but I guess it got lost in
the bug discussion:

http://sourceforge.net/mailarchive/forum.php?thread_name=20090331192030.7634e082%40karr&forum_name=flint-devel

As I wrote in that message, I also need to "translate" polynomials
(i.e., compose with x+k for some constant k) very often. I am not sure
if it's worth introducing new functions for this purpose, since they
can be handled as a special case of composition. Though I still need
fmpz_poly_compose_mod in that case.

Here is a cython file with some of these functions:

This is a part of a patch to Sage to add fast nullspace computation
over QQ(x). It would be great if this functionality was added to FLINT
before I submit the patch to Sage. :)


Thanks.
