4095: [Concept] Add new mouse state (ingame mouse) r=def- a=Jupeyy
This would remove ui_mousesense and use the desktop cursor position instead for menus and editor
This would also fix the editor cursor to not move faster than in menus.
That's probably how most games would handle menus, instead of using relative mouse mode
And this would work for touch inputs.
The normal gameplay relative mouse is ofc NOT affected by any kind
Opinions?
Missing:
- [x] m_MouseSlow in menus
- [x] Make desktop cursor invisible
- [x] Some components that use ui mouse
- [x] Remove focus in/out relative mouse state changes, fixed with next SDL version

4176: Entity switch prediction r=def- a=trml
Adds the prediction for pickups and projectiles (based on #4108)
For blinking entities (deactivated by switch) I also used the extended info to make the blinking effect happen client-side. So instead of the server omitting the projectile/pickup from the snapshot every N ticks (which prevented some things like explosive bullets from being predicted correctly), the server will keep sending the item and let the client decide how to show it.
Added doors as well, and changed how they are sent (and rendered) in a similar way (by always sending both endpoints and using a fixed m_StartTick instead of updating it every tick).
An idea was that this could potentially reduce network traffic a bit (in addition to helping with prediction), especially for stationary items that are rarely/never have to be updated (doors and pickups).
This makes CItems::OnRender a bit more complex, and it could perhaps be cleaned up some way (either using something like CProjectileData, or by moving more of the logic into RenderProjectile/Laser/Pickup).
Some things missing:
- Add more entities (draggers, light, gun)
- Entities are not correctly shown when in super (e.g. doors are shown as closed, and should be open)

Previously, tees could go around the start line on some maps, going
directly to the finish line while leaving one tee behind at the start.
By letting that sole tee start and kill itself, the team could be
directly at the finish at time 0:00.
Fix this by requiring every tee of a team to hit the start line before
being able to finish. Tees can still get some advantage by skipping the
start line, but it will no longer be a 0:00 finish.

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.

3568: Get rid of the MySQL C++ connector as a dependency and disable C++ exceptions r=Learath2 a=heinrich5991
We now use the C API directly. This has the advantage of using one
obscure dependency less, as the C++ connector also used the C API.
Also remove exceptions from database code.
The equivalent code with return codes is a human-assisted mechanical
translation of the old code, no attempts to improve correctness were
made.
This allows us to enable the -fno-exceptions flag.
