Anders Kaseorg 428956c086 zjsunit: Remove set_global side effect from zrequire.
ES6 and TS modules don’t insert themselves into `window`, so our tests
shouldn’t insert them either.  Since the test `window` behaves like
`global` now, we can rely on legacy modules that do insert themselves
to do it themselves.

Anders Kaseorg 28f3dfa284 js: Automatically convert var to let and const in most files.
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.

Anders Kaseorg d17b577d0c js: Purge useless IIFEs.
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.

Priyank Patel e69c2f1aa2 notifications: Send message received from desktop app notification reply.
Adds a electron_bridge event that takes in message id and reply recived from
the notification reply and sends a message. We do this in webapp so desktop
doesn't have to depend on narrow and channel modules.

We also modify zjunit to reset window.electron_bridge after every run
to avoid leaking it.

Anders Kaseorg 1b94733953 webpack: Remove resolve.modules override.
The minimal syntactic sugar it might provide isn’t worth the
unexpected side effects (including side effects on third party
modules).

For now, we allow zrequire to emulate the previous syntax in the Node
test suite, even though stealing part of the NPM namespace is
confusing.

Steve Howell 2f775c3e0b node tests: Extract zrequire helper.
We are phasing out the following in tests:

    add_dependencies - this is just kind of a clunky UI
    require - normal JS requires cause test leaks

In order to plug require leaks, we are effectively doing what
we always have done inside of add_dependencies, which is to
keep track of which modules we have done `require` on, and
these get cleared between tests.

Now we just use `zrequire` every time we want to pull in real
code to our global namespace.

Steve Howell 6c722843ef node tests: Fix namespace leaks related to require().
The node tests have purged modules from cache that were
included via things like set_global(), but calling require
directly would leak modules into the next test, which made
a couple tests only work when you ran the whole suite.  I
fixed those tests to work standalone.  And then I now make
dependencies explicitly clear the require cache before we
require them in namespace.js.

Steve Howell ef3033c79e node tests: Make with_overrides() more granular.
The with_overrides() function no longer works at the module
level, so you can temporarily override one function in a module
without breaking more permanent monkey patches.

This makes us slightly more vulnerable to unintentional test
leakages, but it solves the problem where you often need lots
of temporary overrides for writer functions but you want to
keep a more permanent override for some sort of reader function.

Steve Howell a98999ce27 node tests: Extract with_overrides() helper.
The function with_overrides() uses the logic from the old
run() function in dispatch.js to allow you to call a test
function and override parts of the global namespace only
for the duration of when test_function runs.

Steve Howell d953eca14c Make group PMs reply-to's more consistent in case.
We now sort lists of users ids deterministically, and we also

This probably fixes the bug #2343, although I never got a great
repro on that.

Some node tests used to pass as long as prior tests ran,

cache after each individual test runs.
