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
