Various fixes for sparse warnings.

Define void functions with (void), not ().
Add missing includes.
Some functions were declared static but defined non-static.
Some variables that should be file static were file global but not used in any other file.
prop.h defined a new prop_atoms in each file that included it instead of declaring it extern.
