Subject: lift some things out of the tru64 directory into common directory so
 linux can use it without replication later.

kern/tru64/tru64_events.cc:
kern/tru64/tru64_events.hh:
    lift out SkipFuncEvent and FnEvents since these can be used by any OS.
kern/tru64/tru64_system.cc:
    add system_events (the common OS events file)
