[patch] KConfig: Efficient iterators

[Jarosław Staniek]

For review
I have encountered that every call took more than 1 second and ~100% of CPU on 
my box, in debugging session for KMail (win32/msvc). Strange.

Use KEntryMap::ConstIterator instead of foreach with entryMap.keys().

Infinite loops may take just one second on your box too, _but_ better to 
optimize them :)
