6295: Implement FIFO on Windows using Named Pipes r=def- a=Robyt3

Reimplement the Linux FIFO file server and client controls on Windows by using Named Pipes.

The DDNet server/client acts as a named pipe server and receives messages.
Messages can be posted to the named pipe server by connecting to it as a client.
The named pipe client can for instance be controlled from the command line with PowerShell.

The PowerShell script `scripts/send_named_pipe.ps1` is added for this purpose.
For example the PowerShell command `./send_named_pipe.ps1 "testpipe" "echo a"` sends the command `echo a` to the pipe named `testpipe`.
Multiple commands can be sent at the same time by separating them with semicolons or newlines.

Robert Müller c2c21298e2 Fix signed integer overflow on client input message
Swap mathematical operations to avoid multiplication by `1000`. As `time_freq()` returns the nanoseconds in a second (1e9), first dividing this number by 1000 does not lose any precision.

Also ensure that `IntendedTick` is in the valid range of ticks.

6035: Fix various issues reported by cppcheck static analyser r=def- a=Robyt3

After generating `compile_commands.json` with cmake, I ran [cppcheck](https://cppcheck.sourceforge.io/) like this:

```
cppcheck --project=compile_commands.json -DWIN64 --suppressions-list=cppcheck.supp --enable=all 2>cppcheck.log
```

With these suppressions in `cppcheck.supp`:

```
cstyleCast
useStlAlgorithm
unusedFunction
variableScope
noExplicitConstructor
useInitializationList
noConstructor
uninitMemberVar
uninitMemberVarPrivate
uninitDerivedMemberVar
uninitStructMember
uninitvar
shadowFunction
memleakOnRealloc
internalAstError
virtualCallInConstructor
unknownMacro
noOperatorEq
noCopyConstructor
```

Many of these occur too often or are false positives. 

Here is a list of all remaining non-suppressed issues reported by cppcheck: [cppcheck.log](https://github.com/ddnet/ddnet/files/9997663/cppcheck.log)

And here is a list of all remaining issues including the suppressed ones: [cppcheck_all.log](https://github.com/ddnet/ddnet/files/9997662/cppcheck_all.log)

I couldn't get cppcheck's command line argument to ignore the external folders to work correctly, so I manually removed those entries from the files.

Robert Müller 7ae5b1474a Add TYPE_ALL_OR_ABSOLUTE and TYPE_SAVE_OR_ABSOLUTE storage types
The types are translated to `TYPE_ALL`/`TYPE_SAVE` respectively if a given path is relative and to `TYPE_ABSOLUTE` if a path is absolute.

These types are only supported with the `OpenFile`, `ReadFile`, `ReadFileStr` and `GetCompletePath` methods.

This reduces duplicate code when calling the methods.

Merge #5599
5599: Add support for Rust code in DDNet r=def- a=heinrich5991

The glue is done using the [cxx crate](https://cxx.rs/) on the Rust side.

As a proof-of-concept, only a small console command (`rust_version`) printing the currently used Rust version was added.

You can generate and open the Rust documentation using `DDNET_TEST_NO_LINK=1 cargo doc --open`.

You can run the Rust tests using `cmake --build <build dir> --target run_rust_tests`, they're automatically included in the `run_tests` target as well.

Rust tests don't work on Windows in debug mode on Windows because Rust cannot currently link with the debug version of the C stdlib on Windows: https://github.com/rust-lang/rust/issues/39016.

heinrich5991 dcd76fd3e1 Add support for Rust code in DDNet
The glue is done using the [cxx crate](https://cxx.rs/) on the Rust
side.

As a proof-of-concept, only a small console command (`rust_version`)
printing the currently used Rust version was added.

You can generate and open the Rust documentation using
`DDNET_TEST_NO_LINK=1 cargo doc --open`.

You can run the Rust tests using `cmake --build <build dir> --target
run_rust_tests`, they're automatically included in the `run_tests`
target as well.

Rust tests don't work on Windows in debug mode on Windows because Rust
cannot currently link with the debug version of the C stdlib on Windows:
https://github.com/rust-lang/rust/issues/39016.

Robert Müller 4bb549b68e Initialize the Windows COM library on all threads
Use threading model `COINIT_APARTMENTTHREADED` on threads that own a window (the main client thread) and `COINIT_MULTITHREADED` on all other threads.

Add assertions to ensure that the COM library is initialized successfully and only once per thread.

heinrich5991 884cf75cb8 Stop server if started with old curl and incompatible sv_register

heinrich5991 4f2f3f4bba Only start registering once the server is fully started
This works around, i.e. fixes #5858 for curl versions < 7.77.0, as long
as the servers are only registered via IPv4 **OR** IPv6.

The bug that's being worked around is this:
84d2839740.

The bug makes curl reuse IPv6 connections when it is being requested to
connect via IPv4, making the registering fail. This commit works around
that by letting the server only register after having completely read
the config, so any `sv_register ipv4` should already be in effect.

heinrich5991 716e8cd7f4 Add HTTPS map download URL field for game servers
This allows every game server to provide its own HTTPS server for map
downloads. Since the ingame protocol for downloading map data is very
inefficient, this is desirable. Previously, only servers hosted by DDNet
could benefit from this.

Security concerns:
- Attackers can find out whether a given HTTPS GET request matches a
  known answer.

  This isn't deemed to be problematic as no cookies for authentication
  are sent and only the whole response can be matched.

- Sending requests to honeypot URLs to get people in legal trouble.

  This seems to be already possible with HTML image embeds, so it can't
  be that bad™.

- Downloading huge files, filling up a player's disk. The players might
  cancel when seeing huge files.

  There's a generous limit of 1 GiB per map file.

- Downloading huge files transparently compressed with gzip. See above.

Fixes #5812.

Robert Müller 9a012312b8 Move and extend GetClientVersion to remove many version.h includes
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.

Robert Müller f3fbe891a6 Fix player input player flags translation with sixup
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.
