Eric Blake b513481b9a qapi: Emit structs used as variants in topological order ... Right now, we emit the branches of union types as a boxed pointer, and it suffices to have a forward declaration of the type. However, a future patch will swap things to directly use the branch type, instead of hiding it behind a pointer. For this to work, the compiler needs the full definition of the type, not just a forward declaration, prior to the union that is including the branch type. This patch just adds topological sorting to hoist all types mentioned in a branch of a union to be fully declared before the union itself. The sort is always possible, because we do not allow circular union types that include themselves as a direct branch (it is, however, still possible to include a branch type that itself has a pointer to the union, for a type that can indirectly recursively nest itself - that remains safe, because that the member of the branch type will remain a pointer, and the QMP representation of such a type adds another {} for each recurring layer of the union type).
