  This event is experimental one. It is possible to remove/rename
  flag name after 2.0.1.
* vm_trace.c (get_event_id): return :line if SPECIFIED_LINE was

  This change is a little tricky, so it might be better to prohibit
  module inclusion to refinements.

* include/ruby/ruby.h (RMODULE_INCLUDED_INTO_REFINEMENT): new flag
  to represent that a module (iclass) is included into a refinement.

* class.c (include_modules_at): set RMODULE_INCLUDED_INTO_REFINEMENT
  if klass is a refinement.

* eval.c (rb_mod_refine): set the superclass of a refinement to the
  refined class for super.

* eval.c (rb_using_refinement): skip the above superclass (the
  refined class) when creating iclasses for refinements.  Otherwise,
  `using Refinement1; using Refinement2' creates iclasses:
  <Refinement2> -> <RefinedClass> -> <Refinement1> -> RefinedClass,
  where <Module> is an iclass for Module, so RefinedClass is
  searched before Refinement1.  The correct iclasses should be
  <Refinement2> -> <Refinement1> -> RefinedClass.

* vm_insnhelper.c (vm_search_normal_superclass): if klass is an
  iclass for a refinement, use the refinement's superclass instead
  of the iclass's superclass.  Otherwise, multiple refinements are
  searched by super.  For example, if a refinement Refinement2
  includes a module M (i.e., Refinement2 -> <M> -> RefinedClass,
  and if refinements iclasses are <Refinement2> -> <M>' ->
  <Refinement1> -> RefinedClass, then super in <Refinement2> should
  use Refinement2's superclass <M> instead of <Refinement2>'s
  superclass <M>'.

* vm_insnhelper.c (vm_search_super_method): do not raise a
  NotImplementError if current_defind_class is a module included
  into a refinement.  Because of the change of
  vm_search_normal_superclass(), the receiver might not be an
  instance of the module('s iclass).

* test/ruby/test_refinement.rb: related test.

  Module#refine activates all refinements defined in that module
  only in a given block.

* string.c (sym_to_proc, sym_call): don't use refinements.

* test/ruby/test_refinement.rb: related test.

* iseq.c: add following two methods.
* ISeq#line_trace_all returns all line traces (line numbers)
* ISeq#line_trace_specify(pos, set) set `pos'th line event to
  specified_line event (if set is true).
  These features are introduced for debuggers (mainly to make
  breakpoint).
* iseq.h: add decl. of C APIs.
* test/ruby/test_iseq.rb: add tests.
* vm_trace.c: add `specified_line' event.
* include/ruby/ruby.h: ditto.

* include/ruby/ruby.h (RB_GC_GUARD_PTR): add note.
* vm_backtrace.c (backtrace_to_str_ary): use RB_GC_GUARD() instead of
  RB_GC_GUARD_PTR() which has no effect.
  (backtrace_to_location_ary): ditto.
  (vm_backtrace_to_ary): ditto.

* vm_trace.c: add events
* :thread_begin - hook at thread beggining.
* :thead_end - hook at thread ending.
* :b_call - hook at block enter.
* :b_return - hook at block leave.
  This change slow down block invocation.
  Please try and give us feedback until 2.0 code freeze.
* include/ruby/ruby.h: ditto.
* compile.c (rb_iseq_compile_node): ditto.
* insns.def: ditto.
* thread.c: ditto.
* vm.c: ditto.
* include/ruby/debug.h: add a comment.
* test/ruby/test_settracefunc.rb: add a tests.

* include/ruby/ruby.h (alloca), eval_intern.h (alloca), gc.c
  (alloca): Make alloca() globally available by moving the
  ultimate ifdef's to ruby/ruby.h.  Gcc hides its builtin alloca()
  when compiling with -ansi, and linking thus fails on platforms
  that lack their own alloca() implementation in libc, which
  include OpenBSD and some ports of NetBSD.  We use alloca()
  everywhere including from within third party C extentions, so
  alloca() must be made globally available. [Bug #7307]

* addr2line.c (alloca): Replace the alloca() part with the
  ultimate ifdef's. [Bug #7307]
