Make more file-scope variables static.

Browse Source 
In the previous trawl of this, I didn't bother with the statics in
main-program modules, on the grounds that my main aim was to avoid
'library' objects (shared between multiple programs) from polluting
the global namespace. But I think it's worth being more strict after
all, so this commit adds 'static' to a lot more file-scope variables
that aren't needed outside their own module.
