Currently every function that accepts multiple dimensions does this by itself.

I decided to first see if it would be useful to centralize the dimension parsing and collect inputs before adding it to other functions.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/7051/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull

- [x] Tests added
- [ ] User visible changes (including notable bug fixes) are documented in `whats-new.rst`

I have passed along some more memo dicts, which could prevent some double deep-copying of the same data (don't know how exactly, but who knows :P)
Also, I have found some copy calls that did not pass along the deep argument (I am not sure if that breaks things, lets find out).
And finally I have found some places where shallow copies are enough.

All together it should improve the performance a lot when copying things around.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/7209/reactions"", ""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull
