Update to NetBSD libedit (from Oct 1, 2003), adding some string

cleaning and history bug fixes. The code includes GNU libreadline
functionality, but the corresponding header files are not installed,
since some libreadline functions are missing. There are some minor API
changes, notably:

old: EditLine *el_init(const char *, FILE *, FILE *);
new: EditLine *el_init(const char *, FILE *, FILE *, FILE *);

old: HistEvent *history(History *h, int op, ...);
new: int history(History *h, HistEvent *ev, int op, ...); plus some
changes in operation names. See editline(3) for details.

Tested by djm@, mouring@, jmc@.
