widening: duplicate generateellipsesbundle2() for widening

The widening and the non-widening code are quite different. It will be
clearer to have them as sepearate functions. To start with, I've just
copied it exactly, so it's clearer over the next few patches how
they're different.

The new function should gradually become more similar to
bundle2.widen_bundle(), and should perhaps eventually be merged with
that function. However, I've left it in narrowbundle2.py for now since
it still depends on constants like _KILLNODESIGNAL there.
