	[Bug #20868] Fix Method#hash to not change after compaction

	The hash value of a Method must remain constant after a compaction, otherwise
	it may not work as the key in a hash table.

	For example:

	    def a; end

	    # Need this method here because otherwise the iseq may be on the C stack
	    # which would get pinned and not move during compaction
	    def get_hash
	      method(:a).hash
	    end

	    puts get_hash # => 2993401401091578131

	    GC.verify_compaction_references(expand_heap: true, toward: :empty)

	    puts get_hash # => -2162775864511574135

UnboundMethod only refer defined_class

2022-12-02T23:53:12+00:00

UnboundMethod records caller's class, like `D` or `E` on the
following case:

```ruby
class C
  def foo = :foo
end

class D < C
end

class E < C
end

d = D.instance_method(:foo)
e = E.instance_method(:foo)
```

But `d` and `e` only refers `C#foo` so that UnboundMethod doesn't
record `D` or `E`. This behavior changes the following methods:

* `UnboundMethod#inspect` (doesn't show caller's class)
* `UnboundMethod#==` (`d == e` for example)

Extend tests for a zsuper method of which the method it resolved to has been removed

Make Object#method and Module#instance_method not skip ZSUPER methods

2022-08-20T11:44:00+00:00

Based on https://github.com/jeremyevans/ruby/commit/c95e7e5329140f640b6497905485761f3336d967

Among other things, this fixes calling visibility methods (public?,
protected?, and private?) on them.  It also fixes #owner to show the
class the zsuper method entry is defined in, instead of the original
class it references.

For some backwards compatibility, adjust #parameters and #source_location,
to show the parameters and source location of the method originally
defined. Also have the parameters and source location still be shown
by #inspect.

Clarify documentation of {Method,UnboundMethod}#owner.

Add tests based on the description of https://bugs.ruby-lang.org/issues/18435
and based on https://github.com/ruby/ruby/pull/5356#issuecomment-1005298809

Revert "Add {Method,UnboundMethod}#{public?,private?,protected?}"

2022-08-10T20:02:52+00:00

This reverts commit 27278150685e738f84105d09843d3ba371146c7a and
58dc8bf8f15df9a33d191074e8a5d4946a3d59d5.

Visibility is an attribute of the method entry in a class, not an
attribute of the Method object.

Make define_singleton_method always define a public method

In very unlikely cases, it could previously define a non-public method
starting in Ruby 2.1.
