* Data#members might not be defined, instead it might be defined
on Data subclasses or a module included there. This is notably the
case on TruffleRuby which defines it there for optimization purposes.
In fact the mere presence of Data#members implies a megamorphic call
inside, so it seems best to avoid relying on its existence.

The use of `etc.so` here requires that etc is always implemented
as a C extension on-disk. However at least one impl – JRuby –
currently implements it as an internal extension, loaded via a
Ruby script. This require should simply use the base name of the
library, `etc`, to allow Ruby-based implementations to load as
well.

This class does not exist in any implementation except CRuby.
I would recommend moving this code somewhere else, like a separate
file loaded only on CRuby or into CRuby itself. For now this
change is sufficient to load the library on other implementations.

Before:
```
$ ri sharing_detection=
= .sharing_detection=
(from ruby core)
=== Implementation from PP
------------------------------------------------------------------------
sharing_detection=(b)
------------------------------------------------------------------------
Returns the sharing detection flag as a boolean value. It is false by
default.
```
After:
```
$ ri sharing_detection=
= .sharing_detection=
(from ruby core)
=== Implementation from PP
------------------------------------------------------------------------
sharing_detection=(b)
------------------------------------------------------------------------
Sets the sharing detection flag to b.
```
This causes problems because the hash is passed to a block not
accepting keywords. Because the hash is empty and keyword flagged,
it is removed before calling the block. This doesn't cause an
ArgumentError because it is a block and not a lambda. Just like
any other block not passed required arguments, arguments not
passed are set to nil.
Issues like this are a strong reason not to have ruby2_keywords
by default.
Fixes [Bug #16519]
This removes the related tests, and puts the related specs behind
version guards. This affects all code in lib, including some
libraries that may want to support older versions of Ruby.
We track recursion in order to not infinite loop in ==, inspect, and
similar methods by keeping a thread-local 1 or 2 level hash. This allows
us to track when we have seen the same object (ex. using inspect) or
same pair of objects (ex. using ==) in this stack before and to treat
that differently.
Previously both levels of this Hash used the object's memory_id as a key
(using object_id would be slow and wasteful). Unfortunately, prettyprint
(pp.rb) uses this thread local variable to "pretend" to be inspect and
inherit its same recursion behaviour.
This commit changes the top-level hash to be an identity hash and to use
objects as keys instead of their object_ids.
I'd like to have also converted the 2nd level hash to an ident hash, but
it would have prevented an optimization which avoids allocating a 2nd
level hash for only a single element, which we want to keep because it's
by far the most common case.
So the new format of this hash is:
{ object => true } (not paired)
{ lhs_object => rhs_object_memory_id } (paired, single object)
{ lhs_object => { rhs_object_memory_id => true, ... } } (paired, many objects)
We must also update pp.rb to match this (using identity hashes).
* ast.c (rb_ast_node_type): simplified to return a Symbol without
"NODE_" prefix.

We were missing a `:nodoc:` magic comment that was making automated tools show
that this method was missing documentation, when it really didn't need to be
documented.
