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.

There is a change in behavior: The file is now only reread if the
filename changed, previously it was reread every time.

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.

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 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.

Robert Müller 6d0806f99d Fix engine client flags not being updated under some conditions
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.

Merge #4829 #5343 #5465
4829: Added map_replace_area tool r=def- a=sctt

Motivation:
sometimes mappers need to copy a certain area from a map to another (but also to a different position of the same map).
that's very time consuming on complex maps, as tiles and quads layers have to be manually copied one by one.

map_replace_area is designed to automatically replace all the tiles and quads from a specific area to another.
`Usage: map_replace_area <from_map> <from_x> <from_y> <to_map> <to_x> <to_y> <width> <height> <output_map>`

PoW screenshots attached below.

note: for the moment map_replace_area suppose that you are working on the same map  (that's what i needed), that means source and destination maps must have the same layers structure, or else an error is returned.
but i understand it might be useful to also work on totally different maps, in that case users must be able specify layers they want to consider by associating source map layers to destination map layers (by using a config file maybe).
i'm probably going to make another PR to add this enhancement in the future.

PoW:

5343: Add rcon and chat to integration test r=def- a=ChillerDragon

Add more action to the integration test script: chat messages, chat commands, rcon commands.
This unlocks more code coverage at runtime to catch asan issues.

It adds a very restrictive regex on the log format. But I am happy to maintain that in case changes to the log output happen.
The current version is already supporting heinrichs refactor https://github.com/ddnet/ddnet/pull/5036

Also ensure chat messages arrive in the correct format. Would have catched the following issues:
https://github.com/ddnet/ddnet/issues/5342
https://github.com/ddnet/ddnet/issues/5340
https://github.com/ddnet/ddnet/issues/5302
https://github.com/ddnet/ddnet/pull/5126

5465: Change from pnglite to libpng for PNG reading r=def- a=heinrich5991

This is desirable mainly because libpng is maintained and pnglite is
not. pnglite was last updated in 2007 (15 years ago) and probably has a
lot of security vulnerabilities.

libpng is an actively maintained library also used by browsers like
Firefox or Chromium, so it's less likely to contain security
vulnerabilities, also it's more likely to be packaged by Linux
distributions.

This also refuses to load images of types not supported by pnglite,
which allows us to think about backward compatibility while also
introducing libpng.
