Move time related global variables under TimeManager

Browse Source 
Move OptimumSearchTime, MaximumSearchTime and
ExtraSearchTime in TimeManager.

Note that we remove an useless initialization to 0 because
these variables are used only with time management.

Also introduce and use TimeManager::available_time()

No functional change.
