linenoise: handle SIGWINCH resize signal.
* linenoise/linenoise.c (struct lino_state): New member,
need_resize.
(lino_list_busy): New static variable.
(handle_resize): New function.
(complete_line, history_search, edit): Check for the tty read
being interrupted, and in that case call handle_resize to put
the resize into effect, and continue the loop to fetch another
character.
(sigwich_handler): New function.
(linenoise): If we have SIGWINCH, install a handler for it
temporarily.
(link_into_list, unlink_from_list): Set global busy flag
around list manipulations. The signal handler stays away if
these are set. This means that if the user performs some
action that requires a lino_t to be constructed (e.g. types
Ctrl-R to search), while resizing the window at almost exactly
the same time, we will lose the resize signal. Oh well!
