We have this deepcopy utility in our public API, but it does not work
properly on structs with unexported values. Make a note of that, and
also disallow OutputState from being copied, since OutputState has
required unexported fields that we can't deepcopy.
Not sure if we should special case `OutputState` here, which I've done
since that has come up in particular, or maybe even disallow
deepcopy'ing any values that have unexported fields? That would be a
breaking change though, so I've shied away from it for now.
Fixes https://github.com/pulumi/pulumi/issues/16634
Turn on the golangci-lint exhaustive linter. This is the first step
towards catching more missing cases during development rather than
in tests, or in production.
This might be best reviewed commit-by-commit, as the first commit turns
on the linter with the `default-signifies-exhaustive: true` option set,
which requires a lot less changes in the current codebase.
I think it's probably worth doing the second commit as well, as that
will get us the real benefits, even though we end up with a little bit
more churn. However it means all the `switch` statements are covered,
which isn't the case after the first commit, since we do have a lot of
`default` statements that just call `assert.Fail`.

Certain operations in `engine/diff` mutate engine events during display.
This mutation can occur concurrently with the serialization of the event
for persistence, which causes a panic in the CLI. These changes fix the
offending code and add code that copies each engine event before
persisteing it in order to guard against future issues.
