This is meant to eventually make `xarray.open_dataset` and `xarray.open_mfdataset` work with `pathlib.Path` objects.  I think this can be achieved as follows:

1. In `xarray.open_dataset`, cast any `pathlib.Path` object to string

2. In `xarray.open_mfdataset`, make sure to handle generators.  This is necessary, because `pathlib.Path('some-path').glob()` returns generators.

Curently, tests with Python 2 are failing, because there is no explicit `pathlib` dependency yet.

With Python 3, everything seems to work.  I am not happy with the tests I've added so far, though.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/1514/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull

This PR adds `netCDF4.datetime` objects to the list of allowed data types. These occur, because xarray/conventions.py passes undecoded `netCDF4.datetime` objects if decoding to `numpy.datetime64` fails.
