rb_autoload_str may be safer by preventing premature GC. It
can also be more efficient by passing a pre-frozen string that
can be deduped using rb_fstring. Common autoload callers (e.g.
rubygems, rdoc) already use string literals as the file
argument.
There seems to be no reason to expose rb_autoload_str to the
public C API since autoload is not performance-critical.
Applications may declare autoloads in Ruby code or via
rb_funcall; so merely deprecate rb_autoload without exposing
rb_autoload_str to new users.

This is an implementation detail and should not be exposed to
C extension users. We may change this to id_table soon; and
id_table should not be exposed as a public API.
It is highly unlikely any existing C extensions require this;
so the risk of breakage is very low. Ideally, all of RObject
could be hidden.
