3888: Send server info request for ping with different token r=Jupeyy a=heinrich5991
Thanks to @Jupeyy for figuring out this bug.
Previously, the client would send the request for server info and the
server info ping packet with the same token, making the answer
indistinguishable from each other. Fix this by generating a token that
won't collide.
Fixes#3862.

3884: Make mouse pos calculation more robust against NaNs r=def- a=Jupeyy
1. Since the config didn't have a limit set, they could be negative, which directly caused bugs
2. If you set a min mouse distance, lets say 5, It can mathematically happen that you drag your mouse exactly so much that you hit the (0, 0) point and the if(.. < MinDistance) branch normalizes that point, which causes non restorable NaNs.
It's now safe, the min distance is later in code checked to be atleast 1, i "even" just made it safe enough, so there shouldn't be any change in behaviour:
07ab4d5356/src/game/client/components/controls.cpp (L298-L304)
Which casts the float to an int and checks the int, and this does not restore the mouse pos for NaNs, because nan to int is not 0
its some insanly high value int_max or smth
To reproduce both bugs "easily" on current master you can abuse a SDL limitation,
relative mouse mode seems to only move upto +-1 unit,
- so for 1. set the ingame mouse sens to 100000 and the max mouse distance to -1000 and move your mouse fast for a few seconds, happens relativly easy (Thanks to Souly how to reproduce it)
- for 2. set mouse sens to 100 and max distance to 1 and min distance to 5, this case is a bit harder to reprod in debug mode, probably bcs of the way mouse pos is later handled and also maybe bcs of floating point differences with signs that go close to 0... had to move the mouse few seconds but still got it relativly fast (with -0fast it happens almost instant)
it will exactly happen what i explained in 2. that the reported mouse movement negates the current mouse pos, resulting in mouse pos (0,0)
This this was also a bug reported in #bugs channel, i think we could also add it to the release

3882: Fix inconsistent handling of death tile between front and game layer r=def- a=Zwelf
Fixes#3880
I believe that it can be safely merged. I tried to see the difference, but I couldn't get a measureable difference with only Kill-Tiles and Stoppers.
All affected maps with number of death tiles in front layer (generated with Patigas twmap library):
```

I looked into some of these maps and it doesn't make a difference there.

3873: Add japanese compressed font r=def- a=TsFreddie
This is a 57kb hiragana/katakana font sits between deja vu sans and source han sans. GlowSansJCompressed is a fork of Source Han Sans so the style and license are the same: https://github.com/welai/glow-sans/blob/master/docs/README-en.md
Was torn between condensed (thiner) font and compressed (thinnest) font, but I figure since we want to fit them better, might as well make more text fit rather than less:
The font weight is "book" because glow sans has 9 font weights instead of matching source han sans's 7. so the weight name was shifted.
_Japanese translation will come later._

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.

3826: Respect TuneZone for characters r=def- a=TsFreddie
*I might be totally insane for doing this.
*The effect is only truly noticeable if you have high ping AND dropping packets.*
*clang-tidy's warning doesn't seems to relate to anything I've changed*
Now characters will try to respect TuneZones when ~~evolving and~~ predicting (like projectiles do). Since it is really important to keep TuningList as accurate as possible, I made a TuningList update logic so we try our best to update tunings only for the correct TuneZone (instead of constantly shoving current tuning into TuningList)
And each CCharacterCore now has its own Tunings to avoid any characters influencing GameWorld's tuning. Some server code has to be updated accordingly. I checked the code path, didn't notice anything that would make our server behave differently.
And I guess I should tag @trml myself this time.

3841: Add better support for compose binds in demo menu r=def- a=ChillerDragon
I assume shift is a common compose bind. So users might have bound
shift+scroll or shift+arrowkeys to something else and do not want to
change the playback speed while triggering that compose bind.
I have to admit this is something I personally need and I am not sure what the demand for it is.
But for example my zoom bind is shift+mousewheelup and shift+mousewheeldown and I change that a lot while watching demos but it keeps affecting the playback speed. Maybe someone else has a compose bind using the alt key I do not know. But this solves my issue :)

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.

Automatically determine the approximate location of the client by
including that info in the already fetched https://info2.ddnet.tw/info.
Can be overridden using the the config variable `br_location`.
The current NETMSG_PING and NETMSG_PING_REPLY messages suffer from the
fact that you cannot know whether a given NETMSG_PING_REPLY is from your
NETMSG_PING.
Add tests. Unify behavior of `fs_remove` across operating systems to
only remove files, not directories. Previously on Linux, it would also
delete directories.

3798: Add GLES support r=def- a=Jupeyy
I know i *****ed up, that i didnt move the files in a different commit, but when i noticed it was already too late.
Its mostly disabling stuff that GLES doesn't support. Global LOD bias or glOrtho for examlpe.
~***Strong note***:
This will move ALL linux implementation to GLES instead of GL, since GLES is supported by X11 and wayland, we probably want some testing for this.
This also means, that the default for Linux gets GLES 3.0 which is equivalent to OpenGL 3.3, not OpenGL 3.0!!!~
~If you wonder "why":
Gles just works differently to OGL, it knows about all functions that exists, and e.g. doesn't require GLEW at all, but that also means, that GLES does NOT work while we use OGL, because GLEW would kill GLES.~
GLEW in EGL mode works fine with wayland, just requires X11 to use EGL too(SDL_VIDEO_X11_FORCE_EGL)
_Additionally, for GLES only, only 3.0 and 1.0 context are supported._(doesn't matter anymore for linux)
probably fixes:
~not_really_fixes #3797~
fixes#2885
And would also allow android support, if i ever get these build scripts upto date, or smby is interested into fixing them for me :D
