Several game messages read a 32 bit length and then read that many
characters without checking it, so the loop ran for the whole length
even after the message had ended. The length now has to fit in the
data the message has left. This covers the activity state, cinematic
path, death type, removed item info and inventory group messages and
the shared wide string reader.

The key came from the shared game random engine, which is seeded from
the start time. It now comes from std::random_device through a small
helper. The key stays a 32 bit number, so the packets do not change.
The master and world servers no longer write the key or its hash to
the log.
