Clean up namespace in ast_vgatools.c

- Make local functions static
  This sometimes helps the compiler to optimize.
- Make sure exported functions have 'AST' in their name.
  This avoids name space conflicts with the server or other drivers.
- Place declaration of exported functions in a header file.
  This ensures that changes to the function type or arguments are followed
  thru everywhere.
