Acquiring mutexes is now wraped in a easy to use MUTEX_SECTION macro. This scheme will be extended for chained lock propagation soon. Notes: * NoBug resourcemanagement is now part of the lower layer, RESOURCE_ENTER/RESOUCE_LEAVE are maintained automatically * one must still call RESOURCE_ANNOUNCE/RESOURCE_FORGET, because we want to maintain high level information about resources. * MUTEX_SECTIONS must not be left with any kind of jump
