Add missing 'static' to game-internal declarations.

Another thing I spotted while trawling the whole source base was that
a couple of games had omitted 'static' on a lot of their internal
functions. Checking with nm, there turned out to be quite a few more
than I'd spotted by eye, so this should fix them all.

Also added one missing 'const', on the lookup table nbits[] in Tracks.
