Two unrelated but (I think) small updates in sage.libs.ntl. With these fixes (among others in unrelated modules) all the tests pass for sage.libs.ntl in my Python 3 branch.

The update to ntl_ZZ_pX allows it to take as an argument any object that implements the Sequence protocol, instead of just (list, tuple) exactly. To summarize, this means classes that implement at least __iter__, __len__, and __getitem__ (though to be clear, dict is is not a Sequence). This means, among other things, it can accept range objects without any additional fuss, and there were several examples of this usage in the tests.

Depends on #26769
