The variable `Id` is translated for old clients and is not guranteed to
be the real id. While `m_ClientID` is the real ID. That can also be used
to index the CServer::m_aClients[] array to get the authed state.

Which is using ID 0 as index in the m_aClients array but only ID 63 was
ever initialized.
Call expected server callback functions to simulate clients dynamically connecting and disconnecting when changing the `dbg_dummies` variable. This makes the debug dummies more useful for debugging. Previously, the debug dummies were considered invalid clients, whereas they are now considered to be ingame, so they should behave mostly like real clients being connected to the server. The debug dummies also have correct client names now, e.g. "Debug dummy 42".
The game server code is cleaned up by moving all special handling for debug dummies to the engine server function `CServer::UpdateDebugDummies`.
The left/right direction inputs for debug dummies are now properly added to the client input array, so their input handling should be consistent with normal clients, which fixes some inconsistent prediction with debug dummies.
Allows to do this
```C++
for(const CPlayer *pPlayer : GameServer()->m_apPlayers)
{
if(!pPlayer)
continue;
if(!pPlayer->GetCharacter())
continue;
// your code that does not change the character state
}
```
Add easter, halloween and xmas to `enum ETimeSeason` and `time_season` function. This unifies the logic for detecting these events and seasons in one function. This allows adding support for special easter, halloween and xmas theme maps in the future. The `localtime` function is not used outside `system.c` anymore. The code for detecting easter is taken from upstream.
Using `/timecp` with a player name that has no time on the current map incorrectly cleared the player score/time causing it to not be shown in the scoreboard anymore.
The time of the last kick vote and the time of the last team change are initially in an undefined state, which causes the kick vote and team change to fail due to the delay incorrectly being applied.
Closes#6723.
Replacing the C standard headers with the C++ standard headers causes various `error: call to 'floor' promotes float to double [performance-type-promotion-in-math-fn,-warnings-as-errors]`, which are fixed by using the C++ std math functions or our own math functions instead of the C math functions.
- Use `absolute` instead of `abs` and `fabs`.
- Use `std::floor` instead of `floor` and `floorf`.
- Use `std::ceil` instead of `ceil`, `ceilf` and `round_ceil`.
- Use `std::round` instead of `round` and `roundf`.
- Use `std::sin` instead of `sin` and `sinf`.
- Use `std::asin` instead of `asin` and `asinf`.
- Use `std::cos` instead of `cos` and `cosf`.
- Use `std::acos` instead of `acos` and `acosf`.
- Use `std::tan` instead of `tan` and `tanf`.
- Use `std::atan` instead of `atan` and `atanf`.
- Use `std::pow` instead of `pow` and `powf`.
- Use `std::log` instead of `log` and `logf`.
- Use `std::log2` instead of `log2` and `log2f`.
- Use `std::log10` instead of `log10` and `log10f`.
- Use `std::pow` instead of `pow` and `powf`.
- Use `std::sqrt` instead of `sqrt` and `sqrtf`.
- Use `std::fmod` instead of `fmod` and `fmodf`.
- Use `direction(Angle)` instead of `vec2(std::cos(Angle), std::sin(Angle))`.
- Use `length(vec2(x, y))` instead of `std::sqrt(x * x + y * y)`.
- Remove unused `NormalizeAngular` and `AngularDistance` functions.
Store AFK state of players in `CPersistentClientData` and restore it when a client is connected.
In order for this to work, `m_LastPlaytime` must be adjusted as well to ensure that the AFK state is not reset again automatically by the `AfkTimer` function.
The AFK state is encapsulated using `IsAfk` and `GetAfk`.
Closes#1966.
The `CServer::GetClientVersion` method needs the `version.h` include, so it's moved from the header to the source file, so the include can be removed from the header.
The `GetClientVersion` method is often called with the same `Client != SERVER_DEMO_CLIENT ? GetClientVersion(Client) : CLIENT_VERSIONNR` expression, which also needs the `version.h` include. This expression is moved inside the method, so the include can be removed from all the server entities' and player code.
The `CGameContext::GetClientVersion` method is made a delegate to reduce duplicate code.
The includes of the server entities are also organized further.

5550: Time checkpoints changes r=def- a=C0D3D3V
Fixes#5348
The checkpoint mechanic was last time updated here af44a79b03 and CNetMsg_Sv_DDRaceTime was introduced here: 86365bedcd
The whole design of `CNetMsg_Sv_DDRaceTime` is basically pretty bad, and it was only tired to copy the old broadcast behaviour (that we still have for vanilla client).
We are basically only sending floats (multiplied by 100) instead of using our integer ticks.
Thats also the reason why checkpoints, close to the start (closer than one second), were not displayed (because it was forgotten to multiply m_time by 100 and so it was rounded to 0).
This PR adds a workaround for the problems, but this Net message is just designed wrong and should maybe in the future get updated to use ticks instead of rounded floats.
This PR allows to trigger Time Checkpoints in arbitrary order.
This PR does not make checkpoints unskippable, because we currently have no way to do this, and we have no effect tile that is not skippable (except probably solid blocks).

The sixup translated player flags were previously applied in `OnDirectInput` directly to the player input data.
However, the input data has already been copied at that point, so predicted inputs were using the incorrect flags.
This is fixed by moving the player flags translation to `OnClientPrepareInput`, which is called first and only once on each new player input before it is copied.
The flags were only being updated based on rather arbitrary conditions, so they could never reset to zero or reduced.
The flags are now always updated. The flags are only used in the output of the `status` command.
Makes teehistorian during spawn more reproduceable.
Currently during respawn the first applied input doesn't get recorded.
Always appliying the last sent input fixes this.
