Merge in NetBSD libedit changes and new man pages. Also fix some

strncpy() usage in their code.  NetBSD change log was:
    * add a man page for the editline routines
    * add a man page describing editrc
    * fix bugs in el_parse():
      * didn't execute command when program name matched (test reversed)
      * was checking against empty string instead of program name
      * after checks, command to run also pointed to empty string
    * document ^char and \ escape sequences
    * when parsing ^char control chars, check the correct char when determining
      validity (previously, ^char was a NOP interpreted as the literal string
      because of this bug)
    * Implement CC_REDISPLAY, which (unlike CC_REFRESH) redraws the entire input
    * line (a la ^R). This is useful if the binding outputs information and
    * mucks up the input line. To be used in ``list-choices'' bindings (refer
    * to the ^D binding in csh when filec is set)
