Merge #13235: Break circular dependency: init -> * -> init by extracting shutdown.h

1fabd59e7 Break circular dependency: init -> * -> init by extracting shutdown.h (Ben Woosley)
e62fdfeea Drop unused init.h includes (Ben Woosley)

Pull request description:

  Most includers just wanted to react to pending shutdown.

  This isolates access to `fRequestShutdown` and limits access to the shutdown api functions, including the new `CancelShutdown` for setting it to `false`.
