On Windows, the check was incorrectly using logical or instead of bitwise or. Checking for the flag `FILE_ATTRIBUTE_REPARSE_POINT` is not necessary, as the `FILE_ATTRIBUTE_DIRECTORY` will correctly be set when the target of a symbolic link is a directory. This otherwise causes symbolic links to files to be incorrectly handled as directories.
On Linux, the minor performance optimization of using `entry->d_type` is reverted and `fs_is_dir` is used instead. This internally uses `stat`, which correctly returns the attributes for the symbolic link targets.
5749: Editor: added the possibility to duplicate layers r=def- a=archimede67
<!-- What is the motivation for the changes of this pull request -->
Suggested by Pulsar a few years ago, I finally had the motivation to do it. We can now duplicate any non-special layer (tiles, quads and sounds) thanks to a button just above the delete button.
![image](https://user-images.githubusercontent.com/13364635/185260070-cd5b4c8f-5827-457c-b505-176751003dbc.png)
For each duplicated layers, all the necessary properties are duplicated, for example name, color, flags, etc.
For a tile layer, all the placed tiles are copied. Same goes for a sound layer, all sources are copied. And for the quads layer, all the quads are duplicated.

5730: Move `CUIRect` to separate file, move `CRenderTools::DrawUIRect/4` to `CUIRect::Draw/4`, merge `CUIEx` into `CUI` r=def- a=Robyt3
Adopt UI refactorings from upstream:
- move `CUIRect` into a separate file
- this allows some includes of `ui.h` to be removed, most importantly in `render.h`
- move `CRenderTools::DrawUIRect/4` to `CUIRect::Draw/4`
- this object orientied calling style makes it easier to write the code
The `CUIEx` class is merged into the `CUI` class, as there is no need for two different UI classes anymore.

- use `CORNER_*` constants and add missing constants
- fix array variable names
- use `size_t`
- extract duplicate computation into constant
- use `ColorRGBA` instead of `vec4`
Make the member variables private and add `SetMin` to replace a usage of the member variables in `CDebugHud`. For completeness/symmetry, `SetMax` is also added.
The return value of `CGraph::InsertAt` was not checked. All uses of the function pass a correct index, so the return value is replaced with an assertion.
As the methods are always called at the same time, they can be combined. This also improves the performance, as the array only needs to be iterated once.
`PossibleCommands` now passes the item index to the callback and returns the total number of items.
Add `EmptyPossibleCommandCallback` as default parameter.
Extend `tune` so the current value of a given tuning variable is printed if no new value is given, so it works like commands in the console. For example `tune player_collision` will print the current value of the variable, whereas `tune player_collision 0` will change the value like before.
Extend `tune_reset` so a single tuning value can be reset to default. For example `tune_reset player_collision` will reset just the `player_collision` tuning, whereas `tune_reset` will reset all to defaults like before.

5715: Use djb2 for snapshot item hashlist r=def- a=Robyt3
The previous hash function was heavily biased towards the hash buckets 64-79, making those buckets overflow faster, which results in snapshot CRC errors and lags.
Using the djb2 hash yields an almost even distribution over the entire range of values.
Source for djb2: http://www.cse.yorku.ca/~oz/hash.html
(we incidentally use the same implementation for `str_quickhash`)
Sample which compares the usage of hash buckets in the test map from #5454 with the old and new hash function: [SnapshotHash.csv](https://github.com/ddnet/ddnet/files/9285148/SnapshotHash.csv) (this table also differentiates between the source and target of the snapshot delta)
Closes#4379.

How this works: parallax values configure perceived distance from camera
when it's moving along x and y axes. Assume that zoom is moving the
camera away and scale layers accordingly, with background layers
(furtherst away) changing the least.
New per-ItemGroup (LayerGroup) setting allows to set the new parallax
value independently from the other two. This can be used to do tricks
like on Time Shop zoom correctly or make it feel like the camera is
changing the field of view at the same time as moving in space.
1. Open any map, including an empty one.
2. Select a brush, e.g. size 2x2.
3. Shift click to repeat the brush over a larger area, e.g. 10x10.
4. This causes a buffer-overflow / crash with ASAN:

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.

5658: Fix game freezing up on duplicate snapshot r=def- a=Fireball-Teeworlds
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

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.
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
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:
```

5633: Adapt upstreams CButtonContainer r=def- a=ChillerDragon
Introduce ``CButtonContainer`` which is used for fading text in teeworlds. There is no fading text in ddnet yet.
This change allows introducing such fading buttons but the main motivation for this change is easier copy & pasting code from ddnet to teeworlds code base and vice versa.
