	[ruby/psych] Fixing compatibility with libyaml 0.2.5

	The main issue is that commas aren't allowed in local tags.  libyaml
	was updated to follow the spec, and our tests were out of date.

	See: https://github.com/yaml/libyaml/issues/196

[ruby/psych] Remove taint support

2019-11-12T01:35:47+00:00

Ruby 2.7 deprecates taint and it no longer has an effect.
The lack of taint support should not cause a problem in
previous Ruby versions.

I'm not sure if the untaint calls in deduplicate are still needed
after the removal of tainting in the parser.  If they are not
needed, they should be removed.

[ruby/psych] Suppress uninitialized instance variable warnings

2019-07-24T22:52:17+00:00

In verbose mode, `test_delegator` in `test/psych/visitors/test_yaml_tree.rb` shows following warning.

https://travis-ci.org/ruby/psych/jobs/562435717#L268
```
/home/travis/build/ruby/psych/test/psych/visitors/test_yaml_tree.rb:10: warning: instance variable @obj not initialized
```

This is because `Psych.load` bypasses #initialize with the #init_with method.

[ruby/psych] Deduplicate hash keys if they're strings

2019-07-24T22:52:16+00:00

https://github.com/ruby/psych/commit/0414982ffd

Do not allocate a string to check if a scalar is an integer

Add test to demonstrate issue deserializing hash with ivar

2019-06-25T06:56:20+00:00

Currently the elements of a hash are revived before any ivar values.
This causes an issue when the `[]=` method references an instance
variable.
