Summary0004755: Optimize EAS memory and time consumption.
DescriptionAs written here:
EAS takes too much memory and time given its rather minor role in the game.
The (Bikerdude et al)'s huge "city" map makes this problem apparent.

The idea is to:
1. Understand asymptotic consumption of both time and memory.
2. Improve asymptotic consumption if possible.
3. Look at low-level memory optimizations, e.g. get rid of reckless STL usage.
4. Check if it possible to build less information if number of elevators is small.
Steps To ReproduceTake the (Bikerdude at al)'s map --- you can download it from related issue 4753. Try to load it ("map city" in console). Measure how much time SetupEAS call takes during loading, and high much it increases memory consumption.
TagsNo tags attached.

Committed a series of improvements in svn rev 8448, 8449, 8450.
It improves time of EAS initialization from 105 kilopenguins to 3 kilopenguins.

Yes, data structures are awfully inefficient, but I guess nobody cares about memory consumption today with x64 mode.
I think this issues can be forgotten.
