Uniformize argument names of "call" functions 

* Callable object: callable, o, callable_object => func
* Object for method calls: o => obj
* Method name: name or nameid => method

Cleanup also the C code:

* Don't initialize variables to NULL if they are not used before their first
  assignement
* Add braces for readability
