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
directive.  ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

Aman Agrawal 0859a91b14 hashchange: Go through hashchange to narrow to All messsages.
We should not allow every function who wants to narrow to All
messages to come up with their own method to do so. This
commit makes existing such functions use hashchange library to
do so.

Remove click event on All message button, it already contains
an <a> tag which navigates correctly.

Aman Agrawal 8b29c38e62 info_overlay: Make them overlays from quasi-overlays.
We always use hashchange.go_to_location method now to open the
info_overlay, this makes sure that the url hash are reliable and
hotkeys don't get confused if an overlay is open or not.

We don't want to change hash to "" (this also doesn't navigates
us to 'All messages' view, hence the bug was not noticed.) on
exit of info_overlay.

Anders Kaseorg 7e5c82291f hashchange: Update state.old_hash before returning early.
This fixes a bug where you can’t open the same overlay twice in a row
in IE 11, which doesn’t support HashChangeEvent.oldURL; it was exposed
by commit 05be16e051 (late 2018).

While here, parse the hash from oldURL in a less ad-hoc way.

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.

Steve Howell 78e20c82a8 settings: Handle back button within settings/orgs panels.
The Casper code that I eliminated here seems to be
bogus, in that I don't think it really waited for
all the clicks.

I **think** the intent of the test was to verify that
when you leave settings and go back into it, it remembers
the panel.  I was able to verify this manually.

Steve Howell 3544688b35 settings: Call replaceState() when entering settings/orgs.
We have an upcoming change that lets us use the
back button after going arrowing through multiple
settings pages.

Without first adding this commit, we would have an
infinite loop when you came back to '#settings' and
then '#settings' would rewrite the url with the current
hash.

Just replacing the browser state allows the browser
to do the right thing.

The history protocol is pretty well supported:

Steve Howell 2a1a55af8a settings: Streamline how we launch settings.
We can eliminate the janky `setup_page` methods
and just pass in section from `hashchanged`.

This sets us up to handle browser history more
nicely when you load '#settings' and we could essentially
redirect you to '#settings/your-account' (or similar
things).  A future commit will address that.

We also use `launch` as the new entry point, which
is more consistent with other modules.

Steve Howell 44ef8baff1 hashchange: Add hash_util.get_hash_category().

Steve Howell bcb142e68e hashchange: Move parse_narrow to hash_util.js.

Steve Howell 4af1061974 Remove unused expected_hash variable.
We stopped setting this nearly five years ago, as part

The big conditional that I removed here should have

Presumably either the browsers handle # -> '' redirects
better now, or we address this somewhere else in our
codebase.

Steve Howell 1804d6c9ce Make back button work for some Settings/Org changes.
This change removes all the complexity around
get_hash_group(), and we now only go into the
"same overlay" logic within Settings or within
Manage Organization, but not between them.

This means if you're in Settings but hit the back
button to something under "#organization" we now
do "more stuff", since we want to err on the side
of reloading sections, etc.

There's not much flicker in my testing, and
this is not a super common transition, anyway.

Steve Howell 779ed37cfa hashchange: Fix update_browser_history() call for settings.
Even prior to my recent change in settings_panel_menu.js,
we were assigning window.location.hash a value that doesn't
have a '#' prefix.  This probably doesn't matter too much
for the browser, but it does confuse our own checks about
whether we're redundantly updating browser history.

Now we prefix the settings hash with '#' and we encorce
this convention with a blueslip error.

Steve Howell 05be16e051 hashchange: Remove is_exit_overlay code.
Just calling update_browser_history is sufficient
here, and we end up short-circuiting some code
in hashchanged():

    * we don't need to set state.old_hash, because
      that's what update_browser_history does
    * we bypass the is_overlay_check, which is always
      false in this context

Steve Howell 7859a441ac bug fix: Avoid spurious calls to subs.change_state.
This diff looks a bit more complicated than it really is.

We had a bug where we'd call subs.change_state for
non-streams-related changes.  The bug probably barely
impacted customers, since it's hard to get into that
situation unless you're in "Settings", and then the
code mostly did nothing.  There's still a deeper issue
of what we actually do want to for settings changes,
but this fix does not address that.

We invert the conditionals related to internal state
changes, so that we can handle internal state changes.

And we make sure to only call subs.change_state if our
"base" is "streams".
