Correctly concatenate pandas.Index objects (#875)

We now have a dedicated method, Coordinate.concat that will correctly
concatenate pandas.Index objects, even if they can't be properly expressed as
NumPy arrays (e.g., PeriodIndex and MultiIndex).

As part of this change, I removed and replaced the internal `interleaved_concat`
routine. It turns out we can do this with an inverse permutation instead, which
results in much simpler and cleaner code. In particular, we no longer need a
special path to support dask.array.

This should help with GH818.
