Robert Müller f3eb93b83a Extend IConsole::PossibleCommands, add index to callback
`PossibleCommands` now passes the item index to the callback and returns the total number of items.

Add `EmptyPossibleCommandCallback` as default parameter.

Merge #5715
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.

Robert Müller 9a012312b8 Move and extend GetClientVersion to remove many version.h includes
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)

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:

The condition `Size < 1` is never true because the previous condition `Size < NET_PACKETHEADERSIZE` (`Size < 3`) already covers it.

5520: Warn about pnglite-incompatible PNGs on load r=def- a=heinrich5991

This allows a larger range of PNGs to be loaded while still maintaining
backward compatibility with older clients by annoying the user.

This warning can be enabled by the `warn-pnglite-incompatible-images`
key in the https://info2.ddnet.tw/info JSON, if the key is not there or
the JSON hasn't been obtained yet, the warning is disabled. Since the
JSON is cached across restarts, it'll be effective for initially loaded
images from the second start.

5624: Move message copy inside `SendPackMsgTranslate` r=def- a=Robyt3

Fix clang warning: Address of stack memory associated with local variable 'aBuf' is still referred to by the stack variable 'tmp' upon returning to the caller.  This will be a dangling reference [clang-analyzer-core.StackAddressEscape]

Mark the input parameters as const pointers and mark the protocol message `Pack` methods as const.

And remove a null check that only serves to hide programmer errors.

Support is incomplete for `leak_ip_address_to_all_servers` (will only

Fixes #5158.

addresses.
