bc7fc7e5c0 Fix #15: Alternate interface to plain readline(), for event loops 
This rather big patch adds support for the GNU Readline alternate
interface, for use with event loops:

    void rl_callback_handler_install (const char *prompt, rl_vcpfunc_t *lhandler);
    void rl_callback_read_char       (void);
    void rl_callback_handler_remove  (void);

The code has been tested using the testit and excallback examples.
Both regular editing and searching works as intended.

Also, the problem with lingering artefacts on screen when scrolling
through the history has been fixed.

This patch adds the unmodified excallback.c from readline.  It was
originally contributed by Jeff Solomon as an example of the alternate
interface to readline.

The following set of patches modify it to work with editline.

2a3b422137 Fix negative array index triggered by i-search 
This is a fix to a bug reported by Claus Fischer.  When doing a reversed
i-search on the history, clear_line() sets rl_point to a negative value,
which is later used by ceol().  The intention is to clear the whole line
for the new Search: prompt, but indexing an array with a negative value
is strongly discouraged.

To prevent this negative indexing from happening we check in ceol() for
rl_point < 0, but we quickly notice another side effect: one lingering
character at the end of line when returning from i-search.  The problem
manifests itself more cleary when having a looooo000ooonong prompt.

The fix is to rub out the extra space, insert the i-search string, and
*then* call ceol() again.

Thanks to Claus for pointing this out!
