convert_to_pointer): Prototypes moved to convert.h
(lookup_argument_method): Use method real name, if necessary.
This improves method checking, gets rid of a cross file type
dependency bug and does a more robust job at laying out classes when
necessary. It unifies the regular methods and constructors lookup. It

invocations. It also fixes random bugs.
