Subject: ruby: avoid using g_system_ptr for event scheduling This patch
 removes the use of g_system_ptr for event scheduling. Each consumer object
 now needs to specify upfront an EventManager object it would use for
 scheduling events. This makes the ruby memory system more amenable for a
 multi-threaded simulation.
