ARROW-4263: [Rust] Donate DataFusion

[andygrove]

This PR is to donate the DataFusion source code (assuming that the vote passes!)

[kou]

Could you update https://github.com/apache/arrow/blob/master/dev/release/00-prepare.sh#L101-L105 ?
And please use git rebase instead of git merge.

[andygrove]

Thanks @kou .. I've actually been trying to figure out git rebase tonight and just asked a question about this on the mailing list.

Is it too late now to rebase this PR?

You can squash the branch this way

git checkout -b ARROW-4263-squash
git fetch apache
git reset --hard apache/master
git merge --squash ARROW-4263
git commit -m "commit message here"
git checkout ARROW-4263
git reset --hard ARROW-4263-squash
git push -f

If you make a mistake you can recover using the reflog. see also https://ohshitgit.com/

(Generally once you have merge commits in a branch, normal rebasing is off the table)

Can you move the test data files to arrow-testing?

@wesm I have created a PR against arrow-testing:

apache/arrow-testing#1

[kou]

Could you re-add a change for https://github.com/apache/arrow/blob/master/dev/release/00-prepare.sh#L101-L105 ?

[andygrove]

Once #3547 and apache/arrow-testing#1 are merged, I can delete the test data file from this PR and update the tests to use the version from arrow-testing

[wesm]

The IP clearance vote is passed

[wesm]

I just merged apache/arrow-testing#1. Let me know when this is ready to merge =)

[andygrove]

@wesm Tests pass for me locally so hopefully we're good to go once Travis has run ...

[andygrove]

Travis is happy

[andygrove]

Appveyor is happy too. Let's do this!

[wesm]

👍

Excited to see this merged, thanks @andygrove
