Instead of prohibiting ‘return undefined’ (#8669), we require that a
function must return an explicit value always or never. This prevents
you from forgetting to return a value in some cases. It will also be
important for TypeScript, which distinguishes between undefined and
void.

ES and TypeScript modules are strict by default and don’t need this
directive. ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

Prettier would do this anyway, but it’s separated out for a more
reviewable diff. Generated by ESLint.

This commit was originally automatically generated using `tools/lint
--only=eslint --fix`. It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
We want to update message.submessages for new events, even
though our couple of widgets (poll/tictactoe) that can process
"update" events currently just apply events as "deltas"
to their current data.
This does fix a subtle issue where you may get incoming
events for a message that the client knows about but which
it hasn't yet activated as a widget. Up until now,
we've rarely seen the bug that's fixed here, since it's
usually the case that as soon as we receive a message, we
widgetize it right away.
For some reason in my original version I was sending both
content and data to the client for submessage events,
where data === JSON.parse(content). There's no reason
to not just let the client parse it, since the client
already does it for data that comes on the original
message, and since we might eventually have non-JSON
payloads.
The server still continues to validate that the payload
is JSON, and the client will blueslip if the server
regressses and sends bad JSON for some reason.
We should probably have a try/catch in MessageListView itself
too, for post-processing kind of stuff, but we want to make
this new module defensive in its own right.
Having submessages will become common enough that the
info message here is too spammy, and there are other
ways to observe incoming submessages if you're doing dev
debugging, which this was originally written for.
This commit lays the foundation to handle submessages for
plugin widgets. Right now it just logs events, but subsequent
commits will add widget functionality.
