using creat_game, uniformly solved using
solve_game and transformed into a strategy
using create_strategy.
Strategy are mealy machines, which can be minimized.

that three execution of a single command return the same output is now
a waste of time.
* tests/core/simdet.test: Remove.
* tests/Makefile.am: Adjust.
Also have simul-max default to 4096 instead of 512, because it's
really simul-trans-pruning that is very slow and need to be limited.
