listener: additional reductions in non-termios build.

* linenoise/linenoise.c (struct lino_state): these members are
now absent in non-termios build: atom_callback, ca_ctx,
rawmode, mlmode, clip, result, buf, plen, pos, sel, end, len,
dlen, dpos, dsel, dend, cols, oldrow, maxrows, history_index,
need_resize, need_refresh, selmode, selinclusive,
noninteractive and undo_stack.
(lino_set_multiline, lino_get_multiline,
lino_set_selinclusive, lino_get_selinculsive,
lino_set_noninteractive, lino_get_noninteractive,
lino_set_atom_cb): Functions now only defined in termios
build.
(linenoise): Adjustments for missing members in non-termios
mode.
(lino_make): We no longer need to set noninteractive to 1 in
non-termios build. The flag no longer exists.
(lino_copy, lino_cleanup): Avoid referencing nonexistent
members in non-termios build.
(lino_set_result): Another termios-only function.

* linenoise/linenoise.h (lino_set_result, lino_clear_screen,
lino_set_multiline, lino_get_multiline, lino_set_selinclusive,
lino_get_selinculsive, lino_set_noninteractive,
lino_get_noninteractive, lino_atom_cb_t, lino_set_atom_cb):
Declare only in termios build.

* parser.c (repl): Add #if HAVE_TERMIOS to avoid using
linenoise features not available in non-termios build, and to
remove any variables that thus become unused.
