kconfig/menuconfig: lxdialog is now built-in
lxdialog was previously called as an external program causing screen to flicker when used. With this patch lxdialog is now built-in. It is loosly based om previous work by: Petr Baudis <pasky@ucw.cz> Following is a list of changes: o Moved build of dialog routings to kconfig Makefile o menubox + checklist uses a new item list to hold all menu items o in util.c implmented helper function to deal with item list o menubox now uses parameters to save scroll state (avoids temp file) o textbox now get text to be displayed as parameter and not a file o make sure to properly delete subwin's before main windows o killed unused files: lxdialog.c msgbox.c o modified return value for ESC to match direct calling o in a few places the code has been adjusted to 80 char wide o in textbox a small refactoring was made to make code remotely readable o in mconf removed all unused stuff (functions/variables) Following is a list of know short comings: a) pressing ESC twice will be interpreted as two ESC presses b) resize does not work. menuconfig needs to be restarted to be adjusted Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
