Pyrex legacy. Even the visible warning level is a global variable 
("LEVEL"). That's a very bad interface.

> Some benefits:
>   - reduce use of global variables
>   - allow more then one cython compiler instance at the time
>   - make it much easy to implement -Werror
>   - cython directives can affect message system (fast_fail, werror)
>   - messages could be easily sorted
