Feature #8571: Refinement inheritance by Module#include

Currently, refinements are not inherited by Module#include.
How about to make using to activate refinements in the ancestors of the specified module?

For example,

  module A
    refine X do ... end
    refine Y do ... end
  end
  module B
    refine Z do ... end
  end
  module C
    include A
    include B
  end

  using C
  # Refinements in A and B are activated here.

In this code,

  using C

is equivalent to

  C.ancestors.reverse_each { |m| using m }

This feature enables you to distribute refinements into different modules, and then package the refinements into one module.

Please note that Module#include does't activate refinements in the argument module.

For example,

  module C
    include A
    include B

    # Refinements in A and B are not activated here.
  end

I've implemented this feature, and have attached the patch.
