Add a unique id to every dive

This id is just held in memory. It's not supposed to be used for anything
but having a unique handle that represents a dive. Whenever you need to
remember a dive across an operation that might change the dive_table, this
is what you should hold on to, not a dive number, a dive pointer, or
anything like that.
