In my non-representative survey, I found that my own sound settings are
at 9 for global volume and 100 for the rest, and for a newbie, it was ~30
for all settings. This should be equivalent given 0.3*0.3=0.09.

Since it causes crashes because another thread just accesses the data.
No one has wanted to fix this, so maybe we should just remove it instead
of having clients crash in editor. I'm wondering how much effort it
would be to make this safe. Would we just have to lock for a short part
or is it basically the entire threaded undo operation that has to be
serialized? (No need for a thread then)

Doesn't help fully against the crashes, just makes them a bit less
likely. Causes VSync to have even more delay. Should find an alternative
(real) fix.
This reverts commit 7d8a142768.
It doesn't do anything right now, all servers advertise a compatible
version.
It might become a compatibility hazard in the future, e.g. DDNet servers
try to advertise a different version string to 0.6 than to 0.7 clients,
because the compatible version filter on 0.6 insists that it starts with
"0.6" and on 0.7 that it starts with "0.7", clearly incompatible.
4514: Implement sv_min_team_size (fixes#3720) r=edg-l a=def-
to prevent too small teams counting as team finishes. You can still
finish with a team smaller than sv_min_team_size, but only get regular

This will require going through all our maps and setting
sv_min_team_size in map config for maps intended for more than 2
players. We will also need to remove all teamranks with smaller teams
from official database.

We had lots of cases of people having ping filter activated. Ping is now
too unreliable to actually filter by it. It can show an old super high
value and then you never see the location again.
3879: Use SDL_FlashWindow to request user's attention r=heinrich5991 a=Jupeyy
We should soon update to SDL 2.0.16 for our bundled libs, but don't merge before this happened.
This drops the remaining X11 dependency.
We should then also use GLEW with EGL for official builds for easy native wayland support(which i discussed before already)

3772: Add client-side HTTP server info r=def- a=heinrich5991
Summary
=======
The idea of this is that clients will not have to ping each server for
server infos which takes long, leaks the client's IP address even to
servers the user does not join and is a DoS vector of the game servers
for attackers.
For the Internet, DDNet and KoG tab, the server list is entirely fetched
from the master server, filtering out servers that don't belong into the
list.
The favorites tab is also supposed to work that way, except for servers
that are marked as "also ping this server if it's not in the master
server list".
The LAN tab continues to broadcast the server info packet to find
servers in the LAN.
How does it work?
=================
The client ships with a list of master server list URLs. On first start,
the client checks which of these work and selects the fastest one.
Querying the server list is a HTTP GET request on that URL. The
response is a JSON document that contains server infos, server addresses
as URLs and an approximate location.
It can also contain a legacy server list which is a list of bare IP
addresses similar to the functionality the old master servers provided
via UDP. This allows us to backtrack on the larger update if it won't
work out.
Lost functionality
==================
(also known as user-visible changes)
Since the client doesn't ping each server in the list anymore, it has no
way of knowing its latency to the servers.
This is alleviated a bit by providing an approximate location for each
server (continent) so the client only has to know its own location for
approximating pings.

3804: HiDPI-aware Resolution List r=def- a=TsFreddie
This is a version of https://github.com/teeworlds/teeworlds/pull/2827
Which gives you a resolution list that allows you to select appropriate window size (which is saved in config and used to initialize videos), while showing the canvas size (which is the drawing resolution), at least on MacOS.
This also fixes incorrect clips that happens without HiDPI enabled, because `Graphics()->ScreenWidth()` (in canvas size) was reported incorrectly before, which is now fixed.
Also, I noticed that `m_DesktopScreenWidth` and `m_DesktopScreenHeight` (in window size in MacOS) is used incorrectly or differently from what it was used during initialization:
* During initialization, DesktopScreenWidth is the "screen width of your desktop", but it was used as the "game window size on your desktop" when checking whether to resize window. I added a separate window size calculation to use during resize.
Also, god, I hope SDL's different sizes and stuff is reported consistently at least in Wayland or X, so please test. I know in Windows they are always in pixel/canvas size so it might not be a huge issue there.
