IIUC two other commits from https://github.com/teeworlds/teeworlds/pull/2594 are not relevant for DDNet (because we're reducing the CPU load differently).

This removes the check for the null-terminator from the while loop, as this is also checked in `str_utf8_forward`, which returns an unchanged size in this case. The comparison `new_size != *size` was previously redundant for that reason.
Update comments and add some empty lines for consistency.

4306: Small optimization of EntityEx snapping r=def- a=trml
This drops sending entityex to old client versions, and for stationary pickups not in switch layer (since they don't benefit from entity ex for prediction).
It also slightly changes how m_StartTick is snapped for CLight and CGun when EntityEx is present (always sets it to 0, which could reduce network traffic slightly). However, this might cause misprediction (or invisible lights/guns) for clients who have already changed their version to 15.6, so can omit this part if wanted.

4341: Make laser doors show correctly when spectating other players r=def- a=trml
Makes the server send the switch state of other players while spectating others, otherwise the switch state of your own player (including when spectating in freeview).
Also changed the client a little to both handle situations where the server only sends one SWITCHSTATE netobject (then it just uses that team) or all (then it chooses the team that maintains the above behavior). I'm not sure if the latter would really be useful (but since the netobject contains a team it would be possible to do so).

4300: Don't call uuid lookup, if the expected type isn't an uuid extended type anyway r=heinrich5991 a=Jupeyy
Most performance loss currently comes from the simple fact that lookupuuid is slow.
This addresses the problem by making sure its only called for net messages, that are extended anyway
`@trml` or `@heinrich5991` can you check if that makes sense without breaking something?
