qapi: Permit alternates with just one branch A union or alternate without branches makes no sense and doesn't work: it can't be instantiated. A union or alternate with just one branch works, but is degenerate. We accept the former, but reject the latter. Weird. docs/devel/qapi-code-gen.txt doesn't mention the difference. It claims an alternate definition is "is similar to a simple union type". Permit degenerate alternates to make them consistent with unions.
