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.

The assigned values are never used, so the assignments can be removed or variable scopes can be reduced.
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
