* eval.c, node.h, thread.c, yarvcore.[ch], eval_intern.h:

  support set_trace_func (incomplete.  id and klass
  don't be passed).  And support Thread#set_trace_func
  which hook only specified thread and Thread#add_trace_func
  which add new trace func instead of replace old one.
  C level API was modified.  See thread.c (logic) and
  yarvcore.h (data structures).
* vm.c, vm_macro.def: add hook points.
* compile.c, insns.def: fix "trace" instruction.
* iseq.c, vm_macro.h: add compile option "trace_instruction".
* test/ruby/test_settracefunc.rb: hook "c-return" of set_trace_func.
