When mapping a QAPI object to the command line, this becomes very visible to users because they have to add one or more useless 'data.' to many option names. As a first step towards avoiding this painful CLI experience, this gets rid of the 'data' indirection internally: The QAPI parser doesn't use a wrapper object as the variant type any more, so the indirection is removed from the generated C types. As a result, the C type looks the same for flat and simple unions now. A large part of this patch is mechanical conversion of C code to remove the 'data' indirection. Conceptually, the important change is that variants can now have flat and wrapped representations. For a transitioning period, we'll allow variants to support both representations in a later patch. Eventually, the plan is to deprecate and remove wrapped representations entirely, unifying simple and flat unions. The externally visible interfaces stay unchanged: Visitors still expect the 'data' wrappers, and introspection still shows it.
