Marc-André Lureau	3d3eacaecc	qobject: use a QObjectBase_ struct By moving the base fields to a QObjectBase_, QObject can be a type which also has a 'base' field. This allows writing a generic QOBJECT() macro that will work with any QObject type, including QObject itself. The container_of() macro ensures that the object to cast has a QObjectBase_ base field, giving some type safety guarantees. QObject must have no members but QObjectBase_ base, or else QOBJECT() breaks. QObjectBase_ is not a typedef and uses a trailing underscore to make it obvious it is not for normal use and to avoid potential abuse.

Markus Armbruster	15280c360e	qdict qlist: Make most helper macros functions The macro expansions of qdict_put_TYPE() and qlist_append_TYPE() need qbool.h, qnull.h, qnum.h and qstring.h to compile. We include qnull.h and qnum.h in the headers, but not qbool.h and qstring.h. Works, because we include those wherever the macros get used. Open-coding these helpers is of dubious value. Turn them into functions and drop the includes from the headers. This cleanup makes the number of objects depending on qapi/qmp/qnum.h from 4551 (out of 4743) to 46 in my "build everything" tree. For qapi/qmp/qnull.h, the number drops from 4552 to 21.

Markus Armbruster	6b67395762	Eliminate qapi/qmp/types.h qapi/qmp/types.h is a convenience header to include a number of qapi/qmp/ headers. Since we rarely need all of the headers qapi/qmp/types.h includes, we bypass it most of the time. Most of the places that use it don't need all the headers, either. Include the necessary headers directly, and drop qapi/qmp/types.h.

Eric Blake	c7eb39cbd4	qapi: Improve use of qmp/types.h 'qjson.h' is not a QObject subtype; include this file directly in .c files that are using it, rather than abusing qmp/types.h for that purpose. Meanwhile, for files that include a list of individual QObject subtypes, it's easier to just use qmp/types.h for that purpose.

Eric Blake	7264f5c50c	qapi: Convert QType into QAPI built-in enum type What's more meta than using qapi to define qapi? :) Convert QType into a full-fledged[] builtin qapi enum type, so that a subsequent patch can then use it as the discriminator type of qapi alternate types. Fortunately, the judicious use of 'prefix' in the qapi definition avoids churn to the spelling of the enum constants. To avoid circular definitions, we have to flip the order of inclusion between "qobject.h" vs. "qapi-types.h". Back in commit `28770e0`, we had the latter include the former, so that we could use 'QObject ' for our implementation of 'any'. But that usage also works with only a forward declaration, whereas the definition of QObject requires QType to be a complete type. [*] The type has to be builtin, rather than declared in qapi/common.json, because we want to use it for alternates even when common.json is not included. But since it is the first builtin enum type, we have to add special cases to qapi-types and qapi-visit to only emit definitions once, even when two qapi files are being compiled into the same binary (the way we already handled builtin list types like 'intList'). We may need to revisit how multiple qapi files share common types, but that's a project for another day.

Eric Blake	55e1819c50	qobject: Simplify QObject The QObject hierarchy is small enough, and unlikely to grow further (since we only use it to map to JSON and already cover all JSON types), that we can simplify things by not tracking a separate vtable, but just inline the code element of the vtable QType directly into QObject (renamed to type), and track a separate array of destroy functions. We can drop qnull_destroy_obj() in the process. The remaining QObject subclasses must export their destructor. This also has the nice benefit of moving the typename 'QType' out of the way, so that the next patch can repurpose it for a nicer name for 'qtype_code'. The various objects are still the same size (so no change in cache line pressure), but now have less indirection (although I didn't bother benchmarking to see if there is a noticeable speedup, as we don't have hard evidence that this was in a performance hotspot in the first place). A future patch could drop the refcnt size to 32 bits for a smaller struct on 64-bit architectures, if desired (we have limits on the largest JSON that we are willing to parse, and will probably never need to take full advantage of a 64-bit refcnt).
