Add a function which is called before every render to
get the number of items it can render. This can be used by
instance to load custom number of items as per its state.
We allow ListWidget instances to pass functions in opts that can
be called after scrolling to determine when to render.
Also, allow a callback function to be called pre render.
This improves the UX of creating a stream for atleast 1000+ users
realm by showing the the stream creation form much faster than
before.
Search, user addition, scrolling worked smoothly on 15k+
users realm as tested on dev setup.
Also, simplebar is used to replace the default scrollbar.
Fixes#16805
Use fully resolvable request paths because we need to be able to refer
to third party modules, and to increase uniformity and explicitness.

This is a deceptively ugly diff. It makes
the actual code way more tidy.
I basically inlined some calls to mock_module
and put some statements in lexical order.
We now just use a module._load hook to inject
stubs into our code.
For conversion purposes I temporarily maintain
the API of rewiremock, apart from the enable/disable
pieces, but I will make a better wrapper in an
upcoming commit.
We can detect when rewiremock is called after
zrequire now, and I fix all the violations in
this commit, mostly by using override.
We can also detect when a mock is needlessly
created, and I fix all the violations in this
commit.
The one minor nuisance that this commit introduces
is that you can only stub out modules in the Zulip
source tree, which is now static/js. This should
not really be a problem--there are usually better
techniques to deal with third party depenencies.
In the prior commit I show a typical workaround,
which is to create a one-line wrapper in your
test code. It's often the case that you can simply
use override(), as well.
In passing I kill off `reset_modules`, and I
eliminated the second argument to zrequire,
which dates back to pre-es6 days.
We still need to write to these globals with set_global because the
code being tested reads from them, but the tests themselves should
never need to read from them.
