Important changes in this commit:
* We only cache message list for "Combined feed" if it is the
default view.
* We modify existing handling of home message list code so that
it can be used to for any message list that we want to cache
using a new `preserve_rendered_state` variable.
* narrow_state.filter() returns the filter of combined feed view list
instead of `undefined`.
* We start fetching messages from the latest message on app load.
* Messages in all messages data and Recent view are always synced.
* If combined feed view list is not cached, we don't track it's
last pointer, effectively sending user to the latest unread
message always .
Now whenever we initiate sending a message, we save / update its draft,
which is deleted on a successful send. Earlier, we did this only for
locally echoed messages. Hence a non locally echoed message's draft
would remain, if created in the timeframe between initiating send and
receiving the same message from the server, which can be significant
for slow connections.
For spectators, the chunk of page_params that originates from
do_events_register isn’t assigned until ui_init.js. That means the
TypeScript type of page_params is mostly a lie during module load
time: reading a parameter too early silently results in undefined
rather than the declared type, with unpredictable results later on.
We want to make such an early read into an immediate runtime error,
for both users and spectators consistently, and pave the way for
runtime validation of the page_params type. As a first step, split
out the subset of fields that pertain to the current user.

Needed for typescript, because we want to preserve
types, so instead of mutating a message object,
we can instead calculate return these values
for a message object before it's created in full.
This commit also renames apply_markdown
to render, see this comment

Some files already were using `noop` in place of `() => {}`.
It's both clearer what it means and is easier to type.
This updates all test files to fully use `noop`, and
adds a shared import from the test lib file.
This should cause no functional changes.
This is part of a multi-step effort to move away
from using stream names to reference streams, now
that it's impossible for a user to write a message
with an invalid stream name (since switching to
the dropdown).
This commit moves mainly two functions from `ui.js` to `message_live_update`,
`update_message_in_all_views` and `update_starred_view`. This is done in favor of
eliminating `ui.js` and also these functions are more closely related to
`message_live_update` module than to `ui` module.
We also move `show_message_failed` and `show_failed_message_success` to `echo.js`
for cleaner seperation of responsibilities.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
