Anders Kaseorg d72423ef21 eslint: Replace empty-returns with consistent-return.
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.

Anders Kaseorg 6ec808b8df js: Add "use strict" directive to CommonJS files.
ES and TypeScript modules are strict by default and don’t need this

Steve Howell f2806a0a06 copy/paste: Extract visible_range() to fix error.
When we tried to copy/paste multiple rows up to
and including the last row in our view, we'd have
a blueslip error when the `for` loop checked the
condition `rows.id(row) <= ...` after we had
called `row = rows.next_visible(row)` on the last
row.  Basically, `rows.id()` would complain
about a non-existent row.

Now we extract that code into `visible_range`, so
that our `while` loop can exit as soon as we found
the last row in the range.

Vaibhav 6191b4d93a copy_and_paste: Change copy div css to match "day mode".
Color and background is made according to "day mode"
exclusively here because when copying the content

This is done to avoid copying the content with dark
background when using the app in night mode.

We can avoid other custom styles since they are wrapped
inside another parent such as `.message_content`.

Vaibhav d285f67afe copy_and_paste: Fix copy/paste behaviour on Firefox.
Firefox and Chrome handle selection of multiple messages differently. FF
creates multiple Ranges and Chrome creates one. Code written previously
terminated when we got an empty Range or Range with same starting and ending
message. This behaviour was incorrect since the selection was valid.

* Check for same message is done after looping through all the ranges now.
* `construct_copy_div` is called once since it is much easier to determine
  start_id and end_id with confidence and this avoids any overlap between
  same message ids.

Extended by tabbott to include a ton of comments on how this works.

Fixes #11805.

Puneeth Chaganti 9c377a05f3 paste: More robust check to verify if clipboard data is an image.
The commit f863a9b567 had modified
jquery.filedrop's paste method to exit early if any of the items in the
clipboardData is of the string kind. The early exit was added to prevent pasting
an image thumbnail for text copied from software like MS Word, instead of
pasting the actual copied text content. When copying an image in a (modern?)
Browser, though, the clipboard seems to contain a html `img` tag item, along
with the actual image file. This resulted in pastes being broken.

This commit modifies the condition checked for the early exit. We now actually
look at the html content in the clipboard to see if it is an `img` tag, in which
case we upload the image, instead of exiting early.

Closes #7130.

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 9eb3bdaf6c page load: Make initializations more explicit.
We now initialize most modules in ui_init.js, which
isn't the perfect place to do it, but at least now
we have a mostly consolidated entry point.

All the new foo.initialize() methods introduced in
this module run the same order relative to each
other as before this commit. (I did some console
logging with a hacked version of the program to
get the order right.)  They happen a bit later than
before, though.

A couple modules still have the `$(function() {`
idiom for miscellaneous reasons:

       archive - is a different bundle
       common - used elsewhere
       list_render - non-standard code style
       scroll_bar - no exports
       setup - probably special?
       socket - $(function () is nested!
       transmit - coupled to socket
       translations - i18n is a bigger problem
       ui_init - this bootstraps everything
