Switch to Reline?

ext/readline is retired

• We have reline that is pure Ruby implementation compatible with ext/readline API. We rely on reline in the future. If you need to use ext/readline, you can install ext/readline via rubygems.org with gem install readline-ext.
• We no longer need to install libraries like libreadline or libedit.
