cgo: implement C unions Unions are somewhat hard to implement in Go because they are not a native type. But it is actually possible with some compiler magic. This commit inserts a special &#34;C union&#34; field at the start of a struct to indicate that it is a union. As such a field cannot be written directly in Go, this is a useful to distinguish structs and unions.

cgo: implement C.struct_ types These types (called elaborated types in C) are used as part of linked lists, among others. This is part an extra feature (to be compatible with CGo C.struct_ types) and part a bugfix: linked lists would result in endless recursion leading to a stack overflow.
