Zulip's logic for garbage-collecting data structures before reloading
was a fix for a Chrome memory leak that lasted across reloads a few
years ago. That memory leak is probably now fixed, and thus logic is
causing lots of JavaScript tracebacks that are probably not useful.
So, let's try removing this cleanup logic (everything but the
still-useful deletion of the event queue).
We no longer let the left arrow put you into the message edit
UI for a message where you can only edit topics, since that is
just confusing to most users.
This change also improves error handling a bit, and it removes
an unnecessary call to rows.id().
Finally, it moves some logic out of message_list.js, so that we
don't have a circular dependency for this codepath.

While it's sometimes nice to put a few selectors on the same line,
it is generally better to have a consistent way of formatting our
selectors, and most of our code up until now lists them vertically.
This change fixes the linter to enforce one selector per line, and
it cleans up the places in the CSS where we had multiple selectors
on the same line.
The advantages of one-per-line are as followers:
* cleaner diffs
* easier to see when multiple areas of the app may have the
same format
* less likely to go over 80 cols
* makes it more clear where we have deep nesting in the
individual selectors
* makes it easier for our linting tools to enforce
whitespace violations
This also fixed an old bug where we had ".landing_page h2, h4", which
sets "h4" styles outside of the landing page.
This fixes an exception we had in the user_activity queue processor
when changing email addresses, since the URL containing the
confirmation key was longer than 50 characters.
If we get reactions for deactivated users, or otherwise missing
users, we only issue a blueslip warning now. The function
get_message_reactions() was indirectly causing blueslip errors
before this fix, but we can downgrade to warnings now that this
function has better unit tests around it.
We eventually want to track deactivated users on the client.

What actually has been done below is to just copy the css class defination
from the latest font-awesome css to be here and since the rest of the stuff
in /third/fontawesome was updated in ee0b16b1ef
we should be able to use this safely until we update all font-awesome class
usage in templates.
Fixes#4302.
Modify `bot_owner_user_ids()` to return the user_ids of only
admins and bot owners instead of all the current active users.
This was causing a traceback on the frontend.
Fixes: #3391.
