The assigned values are never used, so the assignments can be removed or variable scopes can be reduced.
According to cppcheck's `unreadVariable` error.
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.

Snapshot data during demo playback was being stored in an array of `char *` instead of an array of `char`, which caused above aliasing warnings and used 8 times more memory for the snapshot storage than being necessary.

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.
The `Append` method was returning `0` on success while `Load` and `Save` were returning `1`.
Now all three methods use a `bool` as return value and return `true` on success.
The call `SortImages()` is moved inside the `Append` method, as it should always be called when appending succeeded.
Since the vulkan loader drops support for useful extensions (or the extension loading process changed between 1.0 & 1.1, not sure)
Which causes OBS not to work

Using `str_format(aBuf, sizeof(aBuf), "%s", pStr)` is equivalent to `str_copy(aBuf, pStr, sizeof(aBuf))`. Using `str_copy` is more readable and also more efficient as there is no overhead from parsing the format string and from passing varargs.
Slicing a demo opened from command line with an absolute path did not work, as the game only tried to load the source demo from storage instead of using the given absolute path.
Previously the IME was not deactivated when the editor is closed, so `SDL_TEXTINPUT` events where still being reported ingame after exiting the editor.
When entering the editor with a custom bind (e.g. `bind e "cl_editor 1"`) or when opening it from the console while also immediately closing the console (e.g. with `cl_editor 1; toggle_local_console`), the IME state was not properly set to active, so SDL did not report any `SDL_TEXTINPUT` events, leading to editboxes in the editor not receiving any text.
The is fixed by always enabling the IME state when entering the editor, which was previously only done when using the Ctrl+Shift+E hotkey or coincidentally when the editor is activated while the IME is already active, i.e. when the menu or console is open.

5941: Get away from vector for skins r=def- a=Jupeyy
most of the time it uses the index just to get the skin, downloaded skins change the index. Now its simply a heap object and downloaded skins load directly. Also the loading might be a bit faster bcs it had a loop lookup .Also O(1) lookup
not 100% tested. also fixes a bug with favorite skins hopefully

It was only being used for "Leak IP" favorites and LAN servers. Since
KoG has upgraded to latest DDNet, there aren't much servers left that
don't understand the new 64 player info protocol.
Keywords: fstd, dtsf
They are used for two purposes, coloring gametypes in the serverbrowser
and enabling backward compatibility. These are independent, we shouldn't
add more stuff to the backward compatibility, hence I split them up and
inlined them.
