Cast `int`s to `unsigned` before subtracting to ensure that integer wrapping is being used instead of causing undefined behavior. Same as in `UndiffItem`.

See #6650.
Add `inp_ime_native_ui` on Windows to use native IME UI instead of rendering the candidate list in the client.
Always set the SDL hint to use native UI on non-Windows, as we cannot determine the list of candidates on those systems.
6585: Add client_score_kind field to serverinfo (followup) r=Robyt3 a=edg-l
followup on #5960 (fixes conflicts)
It specifies whether the scores are to be interpreted as times (string value starting with "time") or as points (string value starting with "points").

6560: Replace EntityEx with new netobjs r=edg-l a=trml
This is a proposal for replacing EntityEx with new netobjects, like suggested in #5860.
- Adds a new DDNetPickup that includes switch number
- a new DDNetProjectile that replaces the old one (which is renamed to DDRaceProjectile)
- includes switch number, tunezone and velocity/speed (plus a flag that can be used to send velocitiy of player projectiles with full precision)
- switch number and subtype is added to DDNetLaser (to distinguish e.g. draggers with different strength)
The pr removes EntityEx from the server, but keeps compatibility in the client.

6466: Fix rcon login when disconnecting dummy and when username used r=def- a=Robyt3
When connecting a dummy and then logging into rcon only the dummy is logged in. When disconnecting the dummy, the main client was not automatically logged in. When logging in with the main client and then connecting the dummy, the dummy was already authenticated automatically. Now the main client is also authenticated automatically when disconnecting an authenticated dummy.
This automatic authentication was also not working correctly if the login used a username, as only the password was stored. Now both username and password are stored to correctly authenticate the main or dummy client.
The stored username and password are completely cleared when disconnecting, so they are not stored in memory longer than necessary.
Closes#5586.

6461: Check if HTTP request task is aborted in completion callback r=def- a=Robyt3
It's possible for the HTTP request task to be aborted after the curl request has finished, so the returned `State` will be `HTTP_DONE` but `m_Abort` is `true`. The `State` never changes to `HTTP_ABORTED`, because the progress callback is not called after the HTTP request has completed.
This causes the client to crash when a skin download is aborted after the HTTP request finished but before the completion callback is called.
This is fixed by checking if `m_Abort` is `true` and setting the `State` to `HTTP_ABORTED` at the beginning of the completion callback.
Closes#3567.

Check if deleting the old map file or renaming the temporary downloaded map fails. If so, show an error message which indicates that the user should delete the map file manually.
Sometimes downloaded map files seem to end up with wrong permissions, ownership or with read-only flag set, which makes the client unable to delete them.

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.

6284: Ensure integer wrapping instead of preventing overflow/underflow r=heinrich5991 a=Robyt3
As the integer overflow/underflow in `UndiffItem` can happen during normal gameplay, we should in this case neither ignore the snapshot delta nor show an error message.
Instead of depending on the particular compiler doing integer wrapping, when integer overflows or underflows occur, we make it part of the design, by casting to `unsigned`, which ensures that integer wrapping is being used.

This fixes issues that prevented vanilla 0.6.5 clients from joining DDNet servers with `sv_vanilla_antispoof 1` (closes#2074).
The dummy map was not valid. The size of the tiles and game layers was calculated incorrectly. The last member variable included in `CMapItemLayerTilemap` version 2 should be `m_Data`. Previously only the size of the member `m_aName` was subtracted from the total size, which was resulting in an incorrect item size, as the size of the following 5 members also needs to be subtracted.
The handshake messages were packed incorrectly. The message ID and the system flag were not added to the six packers that are passed to `SendMsgs`. The lines that are removed in this function seemed to assume that the message ID was already added but not packed, which was no longer the case. Presumable at some point `CMsgPacker` was changed without adapting the vanilla antispoof feature. Now, the message ID and system flag are properly packed when initially creating the message packers.
The `dummy_map` tool is improved to also print the generated map file's hashes and data as a C style array, so the data can immediately be copied to `network_server.cpp`.
As the integer overflow/underflow in `UndiffItem` can happen during normal gameplay, we should in this case neither ignore the snapshot delta nor show an error message.
Instead of depending on the particular compiler doing integer wrapping, when integer overflows or underflows occur, we make it part of the design, by casting to `unsigned`, which ensures that integer wrapping is being used.
One case was a ddnet.tw UUID's string being changed (but the UUID was
not), and the other case is a ddnet.tw UUID's string being changed in
one place but not in another in documentation.
Fixes the commit c479230d71.
CC #5312
Use a different error code for every return statement, so it's easier to determine why unpacking a delta failed.
The codes are grouped by the first digit of the error code:
- `-1xx`: not enough data to read
- `-2xx`: value is invalid
- `-3xx`: could not build snapshot item

When the demo recording is not stopped properly (e.g. client crashes during recording), the timeline markers and the demo length are not updated.
The length is always set to zero when starting the recording, but uninitialized memory is written for the timeline markers, which causes these demos to likely show the maximum number of markers with some markers possibly being outside the ticks that the demo contains.
This is fixed by initially setting all timeline marker data to zero when starting the recording.
The include of `base/system.h` in `src/engine/shared/protocol.h` is not required and only used transitively in `teamscore.h` for `dbg_assert`.
To avoid adding back the include in `teamscore.h`, the function definitions are moved to the cpp file. Both definitions are moved for consistency.

Instead of using hardcoded tick offsets, use the current/previous/next tick values from the demo info.
This fixes seeking the next tick not working for demos where the difference between the current and the next tick was greater than 3.
Each time the client disconnected or stopped a demo, it tried to delete the previous temporary replay file, which causes an error message "could not delete file" to be shown in the console.
This is prevented by clearing the current filename of the demo recorder after deleting the file.
When slicing a demo, also copy the demo markers that are within the sliced segment to the new demo.
This also fixes timeline markers not being added to replay demos, as the replay demos are always created by slicing.

According to cppcheck's `unreadVariable` error.
When stored commands (`CFGFLAG_STORE`) were executed with `CConsole::StoreCommands(false)`, the associated chained commands were not properly executed, if they were chained after the command has been stored (e.g. in `CMenus::OnInit`).
Storing the command saves the current callback and userdata, which were overridden by the chain callback and userdata, but the stored callback and userdata were not updated.
This is fixed by storing a pointer to the command itself, which will be updated when it is chained.
From teeworlds/teeworlds#2572.
The client crashes when trying to unpack a packet that has the sixup flag set, as `CNetClient` does not pass pointers for the output parameters `pSecurityToken` and `pResponseToken` to `CNetBase::UnpackPacket`.
Since the client does not handle sixup packets, checks are added to return an error and ignore the packet instead of crashing due to a null pointer access.
This was found by fuzzing the data returned by `net_udp_recv` with radamsa.

Demo seeking for percent positions and relative time was choppy, when the first and last ticks of the demo are very large but close together (e.g. with 1308908156 to 1308905658, which are close to integer limit).
During the calculation of `WantedTick` both operands were promoted to `float`s, which caused the information of the smaller operand, i.e. the seeked percentage or relative time, to be mostly lost, so seeking was very inaccurate.
This is fixed by rounding the `float` operand to `int` before adding it to another `int`.
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.

This function searches in all subfolder of the given folder and fills the given `std::vector` with all files with the given filename.
A `std::set` is used to prevent duplicate entries when a file with the same path is present in multiple storage locations. In that case we only need the path once, as we only use it against the highest priority storage location anyway.

Pass the original string to the unknown command callback instead of the parsed command, as the latter ends at the first whitespace, which breaks for unknown commands (filenames) containing spaces.

5829: Add HTTPS map download URL field for game servers r=def- a=heinrich5991
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.

Add a non-saved config variable `http_allow_insecure` to re-enable HTTP
support; this is mostly useful for testing stuff.
Disallowing HTTP by default allows fewer insecure data to be sent and
received by the DDNet client.
Merging of DoLaserPreview and static int fix
Replace if else statement with switch function
Adjusted RenderDropDown header to match
static int cbuttoncontainer fix, potential bugs
Previously, close messages were entirely ignored during the connection
process, this meant that ban messages weren't shown to players. Instead,
they'd see the standard "no answer from server yet" message.
Fixes#5792.
Add `IConsole::SetUnknownCommandCallback` to set a callback for unknown commands. The callback is used to handle connect links, .demo and .map files when parsing command line arguments.
This will allow paths/links to be passed at any argument position instead of only the first one.
And this fixes the command `play xyz.demo` not working due to `play ` being considered part of the path.
By updating and rendering the current tick again when changing the spectator mode while the demo playback is paused.
Refactoring: Extract `IDemoPlayer::ETickOffset`, `IDemoPlayer::SeekTick` and `CMenus::DemoSeekTick`.
- Approximate index of wanted keyframe to decrease linear search time.
- Only apply the magic `-5` to the Keyframe calculation, to make seeking with the mouse more accurate.
- After the method returns, the specified tick will be the _next_ tick being played instead of being the current tick.
