this patch (against 2.5.47) cleans up interaction between kconfig's mconf
(menuconfig frontend) and lxdialog. Its commandline interface (called
imaginatively lxdialog) no longer exists, instead a huge .o is packed from the
lxdialog objects and the relevant functions are called directly from mconf.
In practice, this means that drawing on the screen is done with _MUCH_ less
overhead now (we can still do better, maybe I will make few more patches in
future; the difference won't be very big anymore though, I suppose), the screen
updates are better optimalized as ncurses aren't reset everytime you display
something, that also implies that the ugly screen flickering is done. As a cute
side-effect, the dialogs are now rendered on the top of the menu or help panel.
It appears to work fine for me, and the change should cause overall
improvement of the configuration process. Please test, comment, apply ;-).

Note that this is a progeny of the previous kconfig_lxso_mconf.patch - this
one actually creates an .o, not a .so, thus it doesn't need any kbuild
modifications (altough I'm a little anxious from the hacks I had to do). It is
also updated to 2.5.47 and several minor problems were fixed (mainly the prev.
patch was missing a part ;-).
Kind regards,
Petr Baudis
