Multiline history and multiline editing (https://github.com/digikar99…
1fab63e 
…/cl-repl/issues/1, koji-kojiro#58, koji-kojiro#56)

This commit includes a number of inter-related changes:

- A history file is introduced that stores entries in a string-by-string manner,
similar to SLIME. This easily takes care of inputs containing multiple lines.
- To be able to edit a multiline input, the #\newline and #\return signals are
mapped to MAY-BE-INSERT-NEWLINE, which either inserts a newline character, or
completes the command using rl_newline.
- For correct keyboard navigation in the presence of color codes, prompt ignore
codes defined by libreadline are used.
- Some common keys are bound to commands for visiting previous/next line, and
for previous/next input.
