MAINT: cleanup dead code/arguments/fields from ufuncs

The check_return argument and ufunc object field was never used; ditto
for the "new" inner loop selector (which was never implemented), along
with associated typedefs. Since I was looking at this code anyway trying
to figure out which parts were actually in use, I figured I'd clear up
some of the brush to make it easier next time...

    This function is very similar to PyUFunc_FromFuncAndData above, but has
    an extra *signature* argument, to define generalized universal functions.
