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) --HG-- extra : convert_revision : 4d7a843d67459af4d77e433ae3c1b0fbc5f0b56b
