Prevent usage of freed memory by using getLights and getSensors

Instead of separately querying light ids and light infos, just provide a
list of light infos. They already contain the light ids.

This way, we also avoid leaving uninitialized array elements when the
lookup fails.

In the InputReader code, a lock is obtained when the light information
is being read, but that memory could change right after the call
completes.
