2247: Thread safe SQL interaction r=def- a=Zwelf
This PR intends to make the database interaction thread safe and optimizes some SQL queries. This is still a WIP, but since it is a rather big PR I wanted to get feedback early on.
Benefits:
* remove race conditions leading to undefined behavior and potential crashes
* logging game related database results in teehistorian would be possible
Behavior change:
* /top5team prints ranks in reverse order when passing a negative number (like /top5, /top5points)
* Optimize SQL statements for /rank /teamrank /top5 /top5team /points /top5points
* /load without parameters doesn't pass the SQL error to the user (as most other functions)
* Simplify IScore interface
* Add UUID to /save table (update of database schema necessary):
```
ALTER TABLE record_saves ADD SaveID varchar(64);
```
* /save immediately kills team and loads it again if the database insert fails.
still TBD:
* [x] saving (team) score when finishing
* [x] loading team save
* [x] loading initial time and birthday check
* [x] /map and random map votes
* [x] RFC: generate a passphrase (2-3 word) if save-code exists or no save-code is given making /save failures much more rare and save-codes more secure
* [x] clean up code (removing now unused structs, ordering of functions in IScore)

2202: Send DDNet version early in the connection process r=Learath2 a=heinrich5991
This gets rid of the problem that we don't know whether we should send
full snapshots to clients because they haven't told us about them being
DDNet yet.

2212: Use a consistent PRNG on all platforms r=Learath2 a=heinrich5991
I just used glibc's because that is what we use on all the servers. Based on https://www.mscs.dal.ca/~selinger/random/.
Behavior change: The PRNG is actually seeded now.

As discussed on Discord today, can be enabled inside of teams on the fly
during each run on any server. Finishes don't count. I haven't tested
save/load yet, would do that live on the server if this can be merged.
The following member variables:
* m_name to m_aName
* m_String to m_aString
* m_CpCurrent to m_aCpCurrent
* m_Switchers to m_pSwitchers
* SavedTees to m_pSavedTees
This came from a long discussion comparing PCG-* against xoroshiro*. Do
not generate integers without bias because it doesn't affect us very
much and it is easier to reimplement with modulo.

The resource deallocation needs to happen in symmetry with the

Allocations happened in `CAntibot::Init`, but it was not guaranteed that
this was called before the destructor.

Previously, this was only doable with frame-perfect input if you were

This fixes that "deepfly" (flying with deep-frozen dummy, binding both
main and dummy tee hammers onto the same key) does not only work for
good connection.

Mimic old behavior of having a respawn tick > 0 ticks after current tick.
2 ticks later is still "instant enough".
The code below the change mentions strong spawning,
so without deciphering it we simply give 2 extra ticks to make sure that
it executes before spawning (2 instead of 1 so that it definitely
executes for both primary and dummy).
This broke respawn rate limiting and didn't even fix#1828.
When primary tee hits kill tiles, dummy still gets strong hook.
This reverts commit 02f5723321.
Previously, this was only doable with frame-perfect input if you were
going to get frozen again the next tick. Now, you only have to hold your
hammer to immediately hammer once you get unfrozen.
This fixes that "deepfly" (flying with deep-frozen dummy, binding both
main and dummy tee hammers onto the same key) does not only work for
good connection.
Remove the whole copy-and-paste mess.
A seemingly ineffective and apparently code block has been removed.
The broken front layer from the first try has been fixed.

1802: Prediction fixes r=def- a=trml
I believe this fixes#1671 (uninitialized variables).
Some other things: Use new ddnetchar fields in prediction, small fix for prediction of moving pickups, fix the freeze end tick in ddnetcharacter (will add it to the client later)
Also adds a setting for choosing between new/old antiping for grenade like suggested in #1683 (cl_antiping_gunfire 0 to disable).
Co-authored-by: trml <trml@users.noreply.github.com>
OK, maybe not actually remove because it is kept for fallback when the
new method isn't available.
The whole gametype parsing business had the same downsides as user agent
parsing on the web, hence I removed it while keeping behavior the same.
This allows servers to explicitly opt in or out of certain bug
workarounds and other client behavior. This increases the complexity of
different configurations that are available in the client (which is a
bad thing).

1620: Rewrite of prediction code, with additional prediction (updated) r=def- a=trml
This is a reworked attempt at a rewrite of the prediction code (#464), to allow for more client side prediction. It doesn't fix the duplication of server code, but the client code should otherwise be cleaner. This includes separating prediction code out of gamecore/gameclient, and a refactor of the rendering of predicted characters.
There is also prediction for some new things, and some other changes:
- prediction of laser, shotgun, ninja, fng hammer, pickups and ddrace tiles (freeze/unfreeze tiles with cl_predict_freeze)
- laser and bullets are rendered when you fire them and bullets don't go through walls (when both cl_antiping_grenade and cl_antiping_weapons are enabled)
- antiping for flags
- prediction of dummy input
- an additional smoothing option that attempts to make antiping less jumpy (cl_antiping_smooth)
