Greg Price 760cfcc603 resolved_topic: Implement resolve, unresolve, and display. 
We have two different frontend implementations of computing the
un-resolved form of a topic name, and they have a subtle -- but
intentional -- difference in behavior.

Factor them both out into the resolve_topic module, along with
their inverse, and with comments and tests.

Greg Price 7852d8e015 topic_list_data: Move "if resolved" conditionals to a single place. 
These two conditionals are each relying on the other to trigger
on the same condition, and to do complementary things.  Move them
together to a single place so that that relationship is easy to see,
and to refactor.

Greg Price 624cdb0a14 resolved_topic: Start module, in shared package. 
For the moment, just move the RESOLVED_TOPIC_PREFIX constant.
More next.

Anders Kaseorg 513207523c js: Fix various sloppy uses of String#replace. 
Prefer a regexp match over using String#replace to strip expected
prefixes and suffixes because (a) it implicitly verifies that the
input has the expected format and (b) it won’t unexpectedly strip from
the middle of the string.

Austin Riba b22578f975 hash_util: Rename _uri functions to _url. 
It's 2022 and the WHATWG no longer recognizes the term URI. Everything
is now a URL or a type of URL. Which is great because it's way less
confusing. Details here:

Gaurav Pandey 18c546e4b5 left-sidebar: Add support for showing resolve-topic-prefix. 
We currently have the resolved topics prefix shown as part of
the topic name in the left sidebar. However this causes inconsistency
while showing topic names. Hence this adds support for showing the
prefix in the cutter to the left of the topic name.

Fixes #18989.

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.

Hashir Sarwar ee0d4541b4 topic_data: Rename `topic_data` module to `stream_topic_history`. 
`stream_topic_history` is a more appropriate name as this
module will contain information about last message of a
stream in upcoming commits. Function and variable names
are changed accordingly like:

* topic_history() -> per_stream_history()
* get_recent_names() -> get_recent_topic_names()
* name -> topic_name

Steve Howell a0712ab798 minor: Consolidate vars for max topics. 
The two vars here got split apart for temporary
logistical reasons during a recent refactoring.

Now they're just both at the top of
topic_list_data.

Steve Howell fa82d12525 topic list: Extract topic_list_data.js. 
This is mostly for tactical reasons.  It's hard to
get 100% test coverage on topic_list.js, but it
should be easy to get 100% test coverage on this
very important function.

I considered just moving this code into topic_data.js,
but it just didn't feel quite right.  I feel like
this is a pretty core piece of code that's nice
to be by itself and not be near other complicated
code that does stuff like build widgets or talk
to servers.  (And, again, it's not just the actual
code here, which is pretty small, it's the unit
tests, which are inherently verbose to exercise
all the edge cases.)
