Use custom FlatSet to account for allocator changes in flat_set in Boost 1.70.
Boost 1.70 changed the default allocator parameter from new_allocator<T> to void to reduce symbol lenghts.
This reverts the default to the old allocator.

MinMaxLinearEquationSolver: Added a flag 'hasNoEndComponent' that is true if the system is known to have no end components. This decides if policy iteration does require a valid initial scheduler.
Renamed the 'hasNoEndComponents' solver requirement to 'hasUniqueSolution' as this is the actual thing we require for, e.g. sound value iteration.
