The ASIO upgrade was just merged into the master branch of the mongo repo.

Our vendored version of ASIO, src/third_party/asio, is supposed to be identical with a particular branch in our public fork of asio, mongodb-forks/asio. Right now the third_party/... version has changes that have not yet been applied to mongodb-forks.

This ticket is the work to identify the differences between the two and to apply the changes as a series of commits in mongodb-forks/asio.
