Robert Müller a3e48bef27 Prevent temporary demo file from being deleted multiple times
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.

Robert Müller a0553f2d40 Fix editor smooth zooming when joining/reloading game
Using `IClient::LocalTime` for smooth zooming in the editor causes the zoom to behave incorrectly when joining a game, as the local time is reset when joining a game.
This is fixed by adding a separate `IClient::GlobalTime` which is only set once when the client launches and never resets.

Robert Müller 144a69266c Fix client attempting to delete user directory when stopping replay demo
When the client stops a replay demo and tries to remove the temporary file when being disconnected, it's not checked whether a recording of a replay demo has ever been started.
In this case the filename is empty, which leads to the client trying to delete the user's directory, which will fail with an error message, as it's a folder and cannot be deleted with the function designed for deleting files.

This is fixed by calling the function `DemoRecorder_Stop` to delete the temporary demo file, as this function already makes sure that the filename is not empty.

Robert Müller 6d8fad775d Encapsulate m_ResortServerBrowser inside CServerBrowser
The variable `m_ResortServerBrowser` was only used in the client to pass it to the server browser. For better separation of concerns, this variable is moved inside `CServerBrowser` and the function `RequestResort` should be called to set it to `true`.

The existing variable `m_SortOnNextUpdate` is replaced with this, as it served the same purpose already. The variable name from upstream is used to reduce conflicts.

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`:

```

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.

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.

Robert Müller 75326e8393 Fix text input not working when entering editor with bind
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.

Closes #5095.

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

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.

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.

Robert Müller 13961db6a8 Allow demo/map arguments to be relative paths, allow using play
When passing .demo or .map paths as command line arguments, first check if the path can be found in the storage and then try resolving an absolute path.

Also delay execution of the `play` command until the client is ready so the command can be used from the command line. Although it doesn't work if there is only one argument, as this interferes with the .demo file handling.

If a duplicate snapshot is received (for the same tick), we add both to the SnapshotStorage and end up with the same snapshot as both Cur and Prev. This results in GameInfraTick returning "inf" and results in "NaN" downstream in a few places, getting the CollLine logic stuck.

Some debug info (tcpdump, gdb, perf): https://gist.github.com/Fireball-Teeworlds/ad0016d2551a2e4d4cb5691023493856

Apparently this doesn't really happen in the wild, unless you have a buggy network stack. In which case it happens frequently enough to pinpoint the issue :D

 (fixes #5657)

Robert Müller 3863d41623 Validate snapshot size and member variables and demo snapshots
Add `CSnapshot::IsValid` to check if a snapshot unpacked from a snapshot delta or demo is valid:
- ensure number of items and data size are not negative
- ensure that the actual size of the snapshot matches the size derived from its member variables
- ensure item offsets are within the valid range
- ensure item sizes are not negative

Add `CSnapshot::TotalSize` and `CSnapshot::OffsetSize` utility functions.

Minor improvements to related error messages.

Fixes buffer overflow:

5486: Switch to loading screen, when map creation takes too long r=def- a=Jupeyy

Same as #4941 

It doesn't directly fix the issue described in #5478, it does however not trigger it anymore. it's still a bug in our code unrelated  to this. This just triggered the UB from the issue as  `@ardadem` confirmed, SDL received a SDL_QUIT (`[2022-06-23 20:26:31][test]: sdl closed my client, but why xd`)

Now we have a confirmed case that making the window unresponsive can create weird behavior. Similar to the other pr switch to a loading screen after 500ms (this time without menu background map tho, since the menu background map calls the same code).

We really need some fancy loading screen for such situations, even tho they are rare xD

Robert Müller 3f1f94c9d8 Fix segfault in SDL_JoystickClose on client quit
Instead of closing the joysticks manually, use `SDL_QuitSubSystem(SDL_INIT_JOYSTICK)` to quit the entire subsystem, which will also close all joysticks correctly.

The engine input destructor is replaced with a `Shutdown` method so we can control when it is called, i.e. before calling `SDL_Quit`, which forcefully quits all subsystems.

`CJoystick::Close` is removed as we don't need to close joysticks manually anymore.

5106: Fix dummy intended tick sent to server r=def- a=sjrc6

fixes https://github.com/ddnet/ddnet/issues/5044

Currently the dummy gives the server the wrong IntendedTick aka PredTick which (I think) makes it impossible for the server to correctly order inputs if they come early (i.e. if you're playing with high prediction margin).

Currently with dummy copy if you switch dummy with high prediction margin it will almost always desync, with this change it doesn't desync. 

The only reason dummy works at all is because it relies on this code in the server to change the tick that was sent to be the current game tick, if you remove it then dummy hammer and dummy copy breaks but normal players are unaffected.

e9b59e72ff/src/engine/server/server.cpp (L1632-L1633) 

I marked this PR as draft because it seems to cause some unexpected side effects:

with this change if you use dummy copy in solo part your dummy will be visually delayed, this doesn't change anything but it's different from how it was before and I don't understand why. 

the sound effects from hooking with dummy copy are also not as synced as they are with the wrong tick being sent (not sure why) 

I also didn't test all dummy mechanics or any advanced dummy binds which might somehow rely on the broken behavior. 


With wrong tick sent to server:
