3654: Added swap functionality to server client: r=def- a=houseme-kyle

Added a new chat command /swap based on the discussion in the associated issue: 
https://github.com/ddnet/ddnet/issues/1103

Swaps the character's position with another tee using the existing Save/Load functionality. 

Restrictions:
- Has to be in a team similar to the save/load feature

Possible additions:
- Time penalty

**Disclaimer**
This is my first contribution to the project. I tried my best to apply the correct coding standards and understand the purpose of each class/method. Please do provide feedback if used incorrectly.

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.

3605: Adopt some more refactoring from upstream r=heinrich5991 a=Kaffeine

- Backport 'Make spectators stay specs on map changed'
- Adopt upstream refactoring: Mark several functions as 'const'
- CGameContext::SendVoteStatus: Hide the trick for 64 clients
- GameController: Add OnPlayerConnect() like in the upstream
- Move DDRace-specific player initialization code to the Controller. Dependencies:
  - CGameControllerDDRace: Add Score() getter
  - Get rid of gamemode.h with confusing/conflicting definitions (re-defined `GAME_NAME`)
- Replace remaining int64_t by int64 for the sake of consistency

I checked the changes in-game (I ran a server and tested with two players)

heinrich5991 43998ce41a Replace projectile hack with a new extended snapshot object
Still send the old hack to old clients, still accept the old hack from
old servers. This is so F-Client can support DDNet servers without such
hacks.

3535: Fix a possible race in load code  r=def- a=heinrich5991

Previously, a save could possibly be loaded twice given enough latency
discrepancy between servers. The server only verified that it deleted
*some* save with the given password, not *the* save it is trying to
load. This is fixed by also checking the SaveID column that is random
and globally unique (except for the old NULLs). Since users can't create
new saves with NULL SaveID, these pose no problem.

Also change the default UUID for saves without save ID to something
nonzero, so we can't accidentally hit it due to a bug.
