react-resizer appears to be okay at tracking state, but it often desyncs from reality. re-resizer is more maintained and more broadly used (160k downloads vs 110k), and appears to generally do a better job of tracking the cursor.
The new library has some oddities though, such as deltas, touch support (hence the polyfill), and calling handles "Enable".

We don't need the fake clock anymore, but we do have to wait for async actions to complete before moving forward.
This also exposes a number of functions for the store to be puppetted with.

We read/use the options in multiple places, and those places were not in sync. Now when algorithms change and on initial load, both will come to the same conclusions about how to order & sort the rooms.
This fixes a case where a user accepts an invite, which causes a tag change, but the room stays stuck in the invites list. The tag change additionally gets swallowed when the user moves away, causing the room to get lost.
By moving it when we see it, potentially during a sticky room change itself (though extremely rare), we avoid having the room get lost in the wrong lists. A side effect of this is that accepting an invite puts it at the top of the tag it's going to (usually untagged), however this feels like the best option for the user.
A rare case of a tag change happening during a sticky room change is when a leave event comes in for the sticky room, but because it's come through as a tag change it can get swallowed. If it does get swallowed and the user clicks away, the tag change will happen when the room is re-introduced to the list (fake NewRoom event).
Plus a bunch of logging.
This fixes a case where switching rooms would cause the last room you were on to disappear due to an optimization where known NewRoom fires would be translated to tag change fires, which wouldn't re-add the room to the underlying tag algorithm.
By tracking the last sticky room, we can identify when we're about to do this and avoid it.
This commit also adds a check to ensure that we have the latest reference of a room stored as rooms changing from invite -> join change references.
This commit additionally updates the PossibleTagChange handling to be faster and smarter, leading to a more stable generation of the room list. We convert the update cause to a Timeline update in order to indicate it is a change within the same tag rather than having to jump tags. This also means that PossibleTagChange should no longer make it as far as the underlying algorithm.
New logging has also been added to aid debugging.

Disclaimer: this is all of the horrible because it's not meant to be here. Invites in general are likely to move out of the room list, which means this is temporary. Additionally, the communities rework will take care of this more correctly. For now, we support the absolute bare minimum to have them shown.
For example, if you only have 3/10 rooms required for the default then resize smaller, we should have a 'show more' button.
This works by changing the rendering to be slightly more efficient and only looping over what is seen (renderVisibleTiles(), using this.numTiles in place of tiles.length) and using a new setVisibleTilesWithin() function on the layout. Previously resizing the 3/10 case would be setting visibleTiles to ~8 instead of ~1 like it should (because the getter returns a default).
`setKnownRooms` is called to regenerate the room list, and if we don't take the sticky room out of the equation we end up with the room being duplicated. So, to make this easy, we simply remove the sticky room and handle it after the fact.
This small check just ensures that we aren't about to blindly accept that the calling code knows what it is doing. There are some unknown cases where NewRoom gets fired for rooms we already know about, so in those cases we just change it to a PossibleTagChange which is what the caller likely intended.
Many of the edge cases are unknown, though this can happen for an invite being accepted (for example). It's easier to handle it here instead of tracking down every single possibility and fixing it higher up.
When a new room is added there's a fairly good chance that the other events being dispatched will happen in the middle of (for example) the room list being re-sorted. This commit wraps the entire handleRoomUpdate() function for the underlying algorithms in a lock so that if we're unlucky enough to get an update while we're sorting (as the ImportanceAlgorithm splices out what it is sorting) we won't scream about invalid index errors.
We have to do a bit of a dance to return the sticky room to the list so we can remove it, if needed, and ensure that we generally swap the rooms out of the list.
This reverts earlier changes made to textForEvent as they are no longer needed.
This also implements an entire tree of textForEvent-like behaviour as the previews need to be different, which is easiest done with its own stack.
Smaller handle width, small shadow on the top of the show more button if there's more rooms to be shown. The resize handle also only shows when you're hovering in the area now.
The original design called for the shadow to show up only if the user is cutting a tile or dragging, however that is complicated implementation-wise. For speed and encouraging a dogfooding pattern we're going ahead with this behaviour instead.

One of the largest issues with room switching was that we'd regenerate the entire list when the sticky room changes, which is obviously detrimental on larger accounts (and even some medium accounts). To work through this, we simply handle the NewRoom and RoomRemoved causes (used by the sticky room handling) as splices rather than in-place updates.
Overall this leads to a smoother experience as it means we're doing far less calculations and can even opt out of an update if it isn't required, such as a RoomRemoved cause being fired twice - the second one can result in an update not being required, saving render time.
This commit also includes a fix for handling update causes on the sticky room, as the room list loves to print errors when this happens. We don't need to handle any updates because once the sticky room changes it'll get re-added through NewRoom, causing the underlying algorithm to slot it in where needed, effectively handling all the missed updates.
When the user would click 'show more' they would be presented with a 'show less' button that occluded the last room.
Similarly, if they resized the list so that all their rooms would be shown and refreshed the page, they would find their last room covered by the button.
This changes the handling so that showAllClick() sets the height to numTiles + button padding, and adjusts the height calculations on render to deal with relative tiles.
This also removes the conditional padding of the resize handle, as we always occupy the 4px of space. It was leading to rooms getting trimmed slightly by the show N button.
This commit is a bit involved, as it factors the tag specific handling out of `/list-ordering` (and moves the `Algorithm` class one higher as a result), leaving it in the `Algorithm`. The algorithms for list ordering now only know how to handle a single tag, and this is managed by the `Algorithm` class - which is also no longer the base class for the list ordering. The list ordering algorithms now inherit from a generic `OrderingAlgorithm` base class which handles some rudimentary things.
Overall the logic hasn't changed much: the tag-specific stuff has been moved into the `Algorithm`, and the list ordering algorithms essentially just removed the iteration on tags. The `RoomListStore2` still shovels a bunch of information over to the `Algorithm`, which can lead to an awkward code flow however this commit is meant to keep the number of surfaces touched to a minimum.
The RoomListStore has also gained the ability to set per-list (tag) ordering and sorting, which is required for the new room list. The assumption that it defaults from the account-level settings is not reviewed by design, yet. This decision is deferred.
The 'sort by' radio buttons are blocked by https://github.com/matrix-org/matrix-react-sdk/pull/4731 as it contains the styles needed.
The 'unread rooms' checkbox is intentionally not hooked up. This is a more complicated refactoring that needs to be done.
The message preview checkbox works, though the previews remain hardcoded in this change. The primary intent of this change is to have a good enough context menu and the hover states.
The hover states are as described in the design.
This is to fix an issue where when using both the community filter panel and the search box it's an AND rather than further refining the results.
This makes the search box further refine the community filter panel results.

This adds support for:
* Tag changes
* DM changes
* Marking our own rooms as read
* Our own membership changes
The remaining branch we didn't need was the alternate 'new room' branch, so it was removed.
This is not optimized - optimization is deferred.
Originally this was intended to be done only in the importance algorithm, however it is clear that all algorithms will need to deal with this. As such, it has been put into the base class to deal with as we may override it in the future.
This commit should be self-documenting enough to describe what is going on, though the major highlight is that the handling of the sticky room is done by lying to the underlying algorithm.
This has not been optimized for performance yet.

This is an incomplete implementation and is mostly dumped in this state for review purposes. The remainder of the features/bugs are expected to be in more bite-sized chunks.
This exposes the RoomListStore on the window for easy access to things like the new filter functions (used in debugging).
This also adds initial handling of "new rooms" to the client, though the support is poor.
Known bugs:
* [ ] Regenerates the entire room list when a new room is seen.
* [ ] Doesn't handle 2+ filters at the same time very well (see gif. will need a priority/ordering of some sort).
* [ ] Doesn't handle room order changes within a tag yet, despite the docs implying it does.
Sorting and ordering has now been split apart. The ImportanceAlgorithm also finally makes use of the sorting.
So far metrics look okay at 3ms for a simple account, though this could potentially get worse due to the multiple loops involved (one for tags, one for categories, one for ordering). We might be able to feed a whole list of rooms into the thing and have it regenerate the lists on demand.
This is the fruits of about 3 attempts to write code that works. None of those attempts are here, but how edition 4 could work is at least documented now.
This is to get around the problem of a slow dispatch loop. Instead of slowing the whole app down to deal with room lists, we'll just raise events to say we're ready.
Based upon the EventEmitter class.
This does a number of things (sorry):
* Estimates the type changes needed to the dispatcher (later to be replaced by https://github.com/matrix-org/matrix-react-sdk/pull/4593)
* Sets up the stack for a whole new room list store, and later components for usage.
* Create a proxy class to ensure the app still functions as expected when the various stores are enabled/disabled
* Demonstrates a possible structure for algorithms
