* Initialize the diganostics logger with opts.Debug when doing a Deploy, like we do Plan. * Don't spew leaked promises if there were Log.errors. * Serialize logging RPC calls so that they can't appear out of order. * Print stack traces in more places and, in particular, remember the original context for any errors that may occur asynchronously, like resource registration and calls to mapValue. * Include origin stack traces generally in more error messages. * Add some more mapValue test cases. * Only undefined-propagate mapValue values during dry-runs.
