#1438: numpy.trapz() doesn't respect subclass

 numpy.trapz uses asarray() inside the code, which converts arrays that
 were ndarray subclasses. Otherwise, the code can work fine with
 subclasses.

 I've attached a patch that fixes this. No test case, because for some
 reason I can't get masked arrays to fail without my fix.  However, this
 does fix the problem for the python-quantities package.
