Update Kconfiglib and menuconfig to upstream revision e47d7eff1012e, to
add some small fixes/improvements/changes:
- Raise errors for extra trailing tokens anywhere. They were silently
ignored in some places:
* end{if,menu,choice} <extra tokens>
* {default,select,...} FOO <extra tokens> (though e.g.
'default FOO if' raised an error)
- Rephrase the warning when selecting a choice symbol to make it
clearer that select never has any effect on choice symbols.
- Display empty menus with '----' instead of '---> (empty)'. This
matches the C tools. It might be less confusing for symbols defined
with 'menuconfig', which is where you most often get empty menus
(when the symbol is n).
- Speed up parsing performance
