Hirek193 40df8e84f6 zmq: read simulator state from the shared TrainState registry
The zmq interface kept its own copy of the state field list, its own name
table and its own packer. All three are now the shared registry, which
resolves the same channel names and returns the same values, so the wire
format is unchanged. New state exposed to external interfaces is added in
one place from now on.

The registry reports the raw velocity rather than zeroing it while the
simulation is paused, and a symbol which doesn't apply to the current
vehicle keeps its measurement and says so through its quality flag.
