#1884: polyval turns masked array into array

 When using a masked array as input for polyval, then the return is an
 array.  I think it should be a masked array again (or at least document it
 that it is not).

 The fix seems easy, remove the line
 x = NX.asarray(x)
 from np.lib.polyval.  But presumably that line is there for a reason...
