access config via a pointer, not a hardcoded struct address

Browse Source 
this is required so we can elegantly swap out an old config for a
new one in the future and remove lots of boilerplate from config
initialization code.

unfortunately this is a quite intrusive change as the config struct
was accessed in numerous places, but frankly it should have been
done via a pointer right from the start.

right now, we simply point to a static struct in main.c, so there
shouldn't be any noticeable changes in behaviour.
