Anders Kaseorg 9896782fd1 dependencies: Remove XDate.
It’s even more unmaintained than Moment and doesn’t add any
functionality we don’t already have.

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.

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.

YashRE42 b4891a5841 navbar: Rename tab_bar to message_view_header.
Prior to commit eb4a2b9d4e the center
area of the navbar was based on a structure that appended crumbs or
"tabs" as <li>s, forming a tab_bar and a tab_list.

However, in eb4a2b9d4e we apply a new
style and structure to the navbar which lets go of the convention of
tabs. Hence, we'd like to purge the tab_bar and tab_list labels from
our code base.

We purged tab_list in 1267caf5009118875f47fdafe312880af08024e1.

This commit purges tab_bar, it includes:
- A blanket search and replace of tab_bar with message_view_header.
- Splitting a single line comment in
  tab_bar.js / message_view_header.js.
- The renaming of tab_bar.js to message_view_header.js.
- The renaming of tab_bar.hbs to message_view_header.hbs.
- A blanket search and replace of tab_data with
  message_view_header_data.
- Replacing the single occurrence of tabbar with message_view_header
  (it was within a comment.)

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.

Tim Abbott 40916803e7 floating_recipient_bar: Fix incorrect use of jQuery .next().

Tim Abbott 51c6c82003 message_list: Don't split message groups for a date divider.
This adds date dividers within a single message group when the only
reason we had previously been splitting apart two message groups is a
change of date.  The overall effect is a cleaner message list user
experience.

The downside of this change would be that the recipient bars no longer
will always show a new date for date changes; to fix that, we rewrite
how the floating recipient bars both set the date field on the
floating recipient bar itself, as well as ensure that non-floating
recipient bars don't show duplicate dates.

In a future design update where we modify how message recipient bars
look, we may very well be able to simplify this logic by removing some
of the dynamic nature of the recipient bar calculations.  But this is
a good implementation of what remains.

Tweaked significantly by tabbott from Steve Howell's original, both to
extract these changes from a larger PR as well as to modify the
first_visible_message logic to handle some tricky corner cases.

Fixes #10171.

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.

Brock Whittaker d01549e8e3 Fix outerHeight to OR with 0 to not produce NaN.
This is an issue where in jQuery v3 the result of outerHeight on a node
that doesn’t exist is now “undefined” rather than “null”, which means
it will no longer cast to a Number but rather NaN. For this, we create
the safeOuterHeight and safeOuterWidth functions to safely return a
result (or 0).

This is a better solution than manually going to each instance and
ORing it with 0 for type safety.
