4581: Adjustable prediction margin r=def- a=trml
This adds an option to adjust how early the client sends an input for a given tick. In vanilla this value is hardcoded to 10 milliseconds before the next tick, which is good for low-latency gameplay and/or when you have a stable connection, but sometimes it could perhaps be useful to increase the value, to either test something with a high ping (without having to joing a high-ping server or use on a 3rd party program like tc/netem), or for counteracting the effect of jitter and jumping ping.
The last part comes at a tradeoff for higher ping though, and it also doesn't handle lag caused by packet loss, but it I have found it useful in some situations when playing race/solo/dummy with a bad connection. Since it's a bit experimental I only added it as an f1 option and not stored between sessions, and also added a gameinfo flag to only support it on servers that implement #1441.
Edit: Also attempted to cleanup variable names for tick calculations in client.cpp slightly.

4590: Remove extra projectiles r=def- a=trml
Aligns the code with vanilla, and cleans up things a bit
(same as [329e6261f3](url))
These were used to show projectiles a tick (or fraction of a tick) earlier than they otherwise would (and they were also sent without extrainfo since they didn't matter for prediction), so removing them would perhaps not make a noticeable difference. (and perhaps also less of a difference now since weapon input isn't applied before the start of a tick anymore).

4607: Adopt upstream input (especially double click) handling, refactoring r=def- a=Robyt3
This adopts the 0.7 way of handling double clicks, by checking `Event.button.clicks` of the `SDL_Event`. The double click is stored as a flag which is cleared when the `MouseDoubleClick()` function is called (d215c73206 and 7977b46d36).
This reverts 72a6e20, as this hack is no longer required (closes#1745). Double clicking a friend in the friend list still works (#444) with both `gfx_asyncrender_old 0` and `1`.
Refactorings and minor fixes synchronizing with upstream:
- Only copy SDL keystate of _keyboard_ keys and mem_zero the rest to ensure out of bounds SDL keys don't trigger mouse keys.
- Rename variables and use SDL constants.
- Reduce unnecessary indentation.

4306: Small optimization of EntityEx snapping r=def- a=trml
This drops sending entityex to old client versions, and for stationary pickups not in switch layer (since they don't benefit from entity ex for prediction).
It also slightly changes how m_StartTick is snapped for CLight and CGun when EntityEx is present (always sets it to 0, which could reduce network traffic slightly). However, this might cause misprediction (or invisible lights/guns) for clients who have already changed their version to 15.6, so can omit this part if wanted.

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.

3492: Support F-Client and replace non-extended extension messages r=Learath2 a=heinrich5991
This continues what #3439 started, and also replaces non-extended messages that are DDRace extensions with extended messages. The DDNet server still sends the old message to old clients and the DDNet client still understands the old messages.
Supersedes #3439.

GameServer()->SendEmoticon() sends CNetMsg_Sv_Emoticon packet to everyone.
Calling SendEmoticon() from Character::Snap(ClientID) triggers as many
messages to everyone as there are active players.
Move the SendEmoticon() because it is not the Character (a world entity object)
responsibility to celebrate a day. Actually it is not CPlayer responsibility
either but CPlayer is the class where we deciding to celebrate (checking the
date) so at least let's keep the coupled stuff together.
The PLAYERFLAG_AIM can now be set directly on DDNet servers via the 0.7
bridge and will be sent to clients identifying themselves as DDNet
clients.
Add a new extended message that mirror the old `Sv_TeamsState`.
