test/ruby/test_symbol.rb: tests for [Bug #8531]
	* include/ruby/ruby.h, vm_eval.c (rb_funcall_with_block):
	  new function to invoke a method with a block passed
	  as an argument.

	* string.c (sym_call): use the above function to avoid
	  a block sharing. [ruby-dev:47438] [Bug #8531]

	* vm_insnhelper.c (vm_yield_with_cfunc): don't set block
	  in the frame.

	* test/ruby/test_symbol.rb (TestSymbol#test_block_given_to_proc):
	  run related tests.

* include/ruby/ruby.h (RBasic): to be aligned on a VALUE size
  boundary.  [Bug #7647]

  This flag is not contained by RUBY_EVENT_TRACEPOINT_ALL.
  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
  occurred. `:specified_line' never been returned.

  outermost parentheses.

  warnings for unused variables.

* ext/bigdecimal/bigdecimal.c (ENTER): use RB_UNUSED_VAR() to
  suppress annoying warnings by -Wunused-but-set-variable in gcc 4.6.

  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.
