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.
5701: Fix buffer-overflow in editor on shift-clicking brush r=def- a=Robyt3
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
(fixes#5657)

5656: Validate snapshot size and member variables and demo snapshots r=def- a=Robyt3
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 (see #5646):
```
