kconfig: add menu_get_ext_help function to display more information
The three functions are moved from mconf.c, then they can be shared in all menuconfig & gconfig & xconfig & config. +void menu_get_ext_help(struct menu *menu, struct gstr *help) +static void get_prompt_str(struct gstr *r, struct property *prop) +void get_symbol_str(struct gstr *r, struct symbol *sym) Signed-off-by: Cheng Renquan <crquan@gmail.com> Cc: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
