kconfig/lxdialog: support resize
In all dialogs now properly catch KEY_RESIZE and take proper action. In mconf try to behave sensibly when a dialog routine returns -ERRDISPLAYTOOSMALL. The original check for a screnn size of 80x19 is kept for now. It may make sense to remove it later, but thats anyway what much text is adjusted for. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
