readline,repl: add substring based history search
This improves the current history search feature by adding substring
based history search similar to ZSH. In case the `UP` or `DOWN`
buttons are pressed after writing a few characters, the start string
up to the current cursor is used to search the history.
All other history features work exactly as they used to.
