* add RUBY_TYPED_FREE_IMMEDIATELY to data types which only use

2013-10-29T11:16:54+00:00

  safe functions during garbage collection such as xfree().
  On default, T_DATA objects are freed at same points as fianlizers.
  This approach protects issues such as reported by [ruby-dev:35578].
  However, freeing T_DATA objects immediately helps heap usage.
  Most of T_DATA (in other words, most of dfree functions) are safe.
  However, we turned off RUBY_TYPED_FREE_IMMEDIATELY by default
  for safety.

* vm_backtrace.c (rb_profile_frame_full_label): copy from label
  directly, without creating prefix string.

  vm_backtrace.c (rb_profile_frame_full_label): add new C API
  rb_profile_frame_full_label() which returns label with
  qualified method name.
  Note that in future version of Ruby label() may return
  same return value of full_label().
* ext/-test-/debug/profile_frames.c,
  test/-ext-/debug/test_profile_frames.rb: fix a test for this change.

* VALUE rb_profile_frame_method_name(VALUE frame)

* include/ruby/debug.h: add backtrace collecting APIs for profiler.

2013-10-07T07:21:11+00:00

* int rb_profile_frames(int start, int limit, VALUE *buff, int *lines);
  Collect information of frame information.
* VALUE rb_profile_frame_path(VALUE frame);
* VALUE rb_profile_frame_absolute_path(VALUE frame);
* VALUE rb_profile_frame_label(VALUE frame);
* VALUE rb_profile_frame_base_label(VALUE frame);
* VALUE rb_profile_frame_first_lineno(VALUE frame);
* VALUE rb_profile_frame_classpath(VALUE frame);
* VALUE rb_profile_frame_singleton_method_p(VALUE frame);
  Get information about each frame.
  These APIs are designed for profilers, for example, no objectallocation,
  and enough information for profilers.
  In this version, this API collects only collect Ruby level frames.
  This issue will be fixed after Ruby 2.1.
* vm_backtrace.c: implement above APIs.
* iseq.c (rb_iseq_klass): return local_iseq's class.
