altos/lisp: Finish first pass through r7rs
* print -> write, patom -> display * Add read-char, write-char * Add exit, current-jiffy, current-second, jiffies-per-second * Add for-each and string-for-each * Avoid duplicate builtins with different atoms Signed-off-by: Keith Packard <keithp@keithp.com>
