Update books.

[ehuss]

This required some changes in how the books are tested due to some changes in rust-lang/book. It uses new syntax that is not compatible with bare rustdoc --test. This changes it so that it uses rustbook to run the tests, which is essentially the same as mdbook test.

The macOS dist-x86_64-apple builder hung. Azure will not display the logs, and has this message:

##[error]We stopped hearing from agent Azure Pipelines 2. Verify the agent machine is running and has a healthy network connection. Anything that terminates an agent process, starves it for CPU, or blocks its network access can cause this error. For more information, see: https://go.microsoft.com/fwlink/?linkid=846610

I haven't seen this error before. I'm guessing the agent died?
