Aman Agrawal 459e1fc218 sent_messages: Pass correct reference of this in setTimeout.
We explicitly bind `this` to MessageState class which otherwise
was defaulting to `window`.

This resulted in variables like `this.received` and `this.local_id`
being incorrectly interpreted by called function
as `window.(received | local_id)` which are `undefined`.
Hence, frontend thinks that the message was never received.

It was noticed since this was the common log message when
a double message send bug was observed. This change in no
was indicates fixing of the double send bug, but is hopefully
one step forward in that direction.

Anders Kaseorg 6ec808b8df js: Add "use strict" directive to CommonJS files.
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.

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

no longer needed.

Armaan Ahluwalia 6d255efe4c app: Prepare JS files for consumption by webpack.
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.

Steve Howell 3f06f28ad7 sending messages: Extract sent_messages.js.
This commit extract send_messages.js to clean up code related
to the following things:

    * sending data to /json/report_send_time
    * restarting the event loop if events don't arrive on time

The code related to /json/report changes the following ways:

    * We track the state almost completely in the new
      send_messages.js module, with other modules just
      making one-line calls.

    * We no longer send "displayed" times to the servers, since
      we were kind of lying about them anyway.

    * We now explicitly track the state of each single sent
      message in its own object.

    * We now look up data related to the messages by local_id,
      instead of message_id.  The problem with message_id was
      that is was mutable.  Now we use local_id, and we extend
      the local_id concept to messages that don't get rendered
      client side.  We no longer need to react to the
      'message_id_changed' event to change our hash key.

    * The code used to live in many places:
        * various big chunks were scattered among compose.js,
          and those were all moved or reduced to one-line
          calls into the new module
        * echo.js continues to make basically one-line calls,
          but it no longer calls compose.report_as_received(),
          nor does it set the "start" time.
        * message_util.js used to report received events, but
          only when they finally got drawn in the home view;
          this code is gone now

The code related to restarting the event loop if events don't arrive
changes as follows:

    * The timer now gets set up from within
      send_messages.message_state.report_server_ack,
      where we can easily inspect the current state of the
      possibly-still-in-flight message.

    * The code to confirm that an event was received happens now
      in server_events.js, rather than later, so that we don't
      falsely blame the event loop  for a downstream bug.  (Plus
      it's easier to just do it one place.)

This change removes a fair amount of code from our node tests.  Some
of the removal is good stuff related to us completing killing off
unnecessary code.  Other removals are more expediency-driven, and
we should make another sweep at ramping up our coverage on compose.js,
with possibly a little more mocking of the new `send_messages` code
layer, since it's now abstracted better.

There is also some minor cleanup to echo.resend_message() in this
commit.

See #5968 for a detailed breakdown of the changes.

Steve Howell 475eb21a5e Revert commits related to client_message_id.
I pushed a bunch of commits that attempted to introduce
the concept of `client_message_id` into our server, as
part of cleaning up our codepaths related to messages you
sent (both for the locally echoed case and for the host
case).

When we deployed this, we had some strange failures involving
double-echoed messages and issues advancing the pointer that appeared
related to #5779.  We didn't get to the bottom of exactly why the PR
caused havoc, but I decided there was a cleaner approach, anyway.

Steve Howell fe66d4f3b0 Encapsulate message_state.maybe_restart_event_loop().
We now set the timer for missing events inside the
message_state class, where it's easier for us to know
which state we're in.

Steve Howell bc67f6a8ca Add sent_messages.track_messages().
This change has us tracking messages as soon as we start
sending the message to the server.  The next step is to
reconfigure the timeouts a bit to deal with the server not
responding.

Steve Howell 9ee2be4a0d Use client_message_id as key for sent_messages lookups.
We now use a client-side message id to track the state of our
sent messages.  This sets up future commits to start tracking
state earlier in the message's life cycle.

It also avoids ugly reify logic where we capture an event to
update our data structure to key on the server's message id
instead of the local id.  That eliminates the node test as well.

Another node test gets deleted here, just because it's not
worth the trouble with upcoming refactorings.

Steve Howell 68f8ba0449 Generate client_message_id() sequentially.
This commit starts to decouple client_message_id from local_id.

We don't really take advantage of the decoupling in this
commit--in fact, it's a bit of a pain at first.  But this should
be a fully working checkpoint commit.

Steve Howell 25b59d0044 Extract sent_messages.message_state class.
This class helps us encapsulate the state of a message, with all
the dates/flags that get sent as part of /json/report_send_time.

Steve Howell f6d670ae3d Extract sent_messages.js.
This is mostly straightforward moving of code out of compose.js.

The code that was moved currently supports sending time
reports for sent messages, but we intend to grow out the new
module to track more state about sent messages.

The following function names in this commit are new, but their
code was basically pulled over verbatim:

    process_success (was process_send_time)
    set_timer_for_restarting_event_loop
    clear
    initialize

All the code in the new module is covered by previous tests that
had been written for compose.js.  This commit only modifies
a few things to keep those tests.

The new module has 100% node coverage, so we updated `enforce_fully_covered`.
