libffi needs to be updated to the current version for Windows builds to make it easier to add ARM support

Would it be possible to add a What's New in Python 3.8 entry about this change? IMHO it is big and important enough to be mentioned ;-) I also wanted libffi_msvc/ to be removed. Thanks!

I also wanted libffi_msvc/ to be removed.

An empty directory is not really tracked by git, you should be able to just remove it manually without any problems, alternatively you could try

git clean -fd # on a clean tree

add -n for dry run.

I am talking about the commit whixh removed the directory. I am happy that
someone succeeded to write it ;-)

[paulmon]

Would you like me to submit a PR to the What's New doc?
