Several functions return values by reference parameters. This is realized
by passing the members of remote_CALL_ret by reference to the called
function.

The position of this parameters in the function signature follows some
patterns with some exceptions. This patterns and exceptions are hardcoded
in the generator.

Add an insert@<offset> annotation to the remote_CALL_ret struct members
for functions that return lists to remove some of the hardcoded patterns
and exceptions.
