fa34a3c58a Use DECLARE_*CHECKER* when possible (--force mode)
Separate run of the TypeCheckMacro converter using the --force
flag, for the cases where typedefs weren't found in the same
header nor in typedefs.h.

Generated initially using:

 $ ./scripts/codeconverter/converter.py --force -i \
   --pattern=TypeCheckMacro $(git grep -l '' -- '*.[ch]')

Then each case was manually reviewed, and a comment was added
indicating what's unusual about those type checking
macros/functions.  Despite not following the usual pattern, the
changes in this patch were found to be safe.

db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

94dfc0f343 codeconverter: script for automating QOM code cleanups
This started as a simple script that scanned for regular
expressions, but became more and more complex when exceptions to
the rules were found.

I don't know if this should be maintained in the QEMU source tree
long term (maybe it can be reused for other code transformations
that Coccinelle can't handle).  In either case, this is included
as part of the patch series to document how exactly the automated
code transformations in the next patches were done.

f84203a8c2 qom: provide convenient macros for declaring and defining types
When creating new QOM types, there is a lot of boilerplate code that
must be repeated using a standard pattern. This is tedious to write
and liable to suffer from subtle inconsistencies. Thus it would
benefit from some simple automation.

QOM was loosely inspired by GLib's GObject, and indeed GObject suffers
from the same burden of boilerplate code, but has long provided a set of
macros to eliminate this burden in the source implementation. More
recently it has also provided a set of macros to eliminate this burden
in the header declaration.

In GLib there are the G_DECLARE_* and G_DEFINE_* family of macros
for the header declaration and source implementation respectively:

  https://developer.gnome.org/gobject/stable/chapter-gobject.html
  https://developer.gnome.org/gobject/stable/howto-gobject.html

This patch takes inspiration from GObject to provide the equivalent
functionality for QOM.

In the header file, instead of:

    typedef struct MyDevice MyDevice;
    typedef struct MyDeviceClass MyDeviceClass;

    G_DEFINE_AUTOPTR_CLEANUP_FUNC(MyDeviceClass, object_unref)

    #define MY_DEVICE_GET_CLASS(void *obj) \
            OBJECT_GET_CLASS(MyDeviceClass, obj, TYPE_MY_DEVICE)
    #define MY_DEVICE_CLASS(void *klass) \
            OBJECT_CLASS_CHECK(MyDeviceClass, klass, TYPE_MY_DEVICE)
    #define MY_DEVICE(void *obj)
            OBJECT_CHECK(MyDevice, obj, TYPE_MY_DEVICE)

    struct MyDeviceClass {
        DeviceClass parent_class;
    };

We now have

    OBJECT_DECLARE_SIMPLE_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE)

In cases where the class needs some virtual methods, it can be left
to be implemented manually using

    OBJECT_DECLARE_TYPE(MyDevice, my_device, MY_DEVICE)

Note that these macros are including support for g_autoptr() for the
object types, which is something previously only supported for variables
declared as the base Object * type.

Meanwhile in the source file, instead of:

    static void my_device_finalize(Object *obj);
    static void my_device_class_init(ObjectClass *oc, void *data);
    static void my_device_init(Object *obj);

    static const TypeInfo my_device_info = {
        .parent = TYPE_DEVICE,
        .name = TYPE_MY_DEVICE,
        .instance_size = sizeof(MyDevice),
        .instance_init = my_device_init,
        .instance_finalize = my_device_finalize,
        .class_size = sizeof(MyDeviceClass),
        .class_init = my_device_class_init,
    };

    static void
    my_device_register_types(void)
    {
        type_register_static(&my_device_info);
    }
    type_init(my_device_register_types);

We now have

    OBJECT_DEFINE_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE)

Or, if a class needs to implement interfaces:

    OBJECT_DEFINE_TYPE_WITH_INTERFACES(MyDevice, my_device, MY_DEVICE, DEVICE,
                                       { TYPE_USER_CREATABLE }, { NULL })

Or, if a class needs to be abstract

    OBJECT_DEFINE_ABSTRACT_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE)

IOW, in both cases the maintainer now only has to think about the
interesting part of the code which implements useful functionality
and avoids much of the boilerplate.

c5a61e5a3c qom: make object_ref/unref use a void * instead of Object *.
The object_ref/unref methods are intended for use with any subclass of
the base Object. Using "Object *" in the signature is not adding any
meaningful level of type safety, since callers simply use "OBJECT(ptr)"
and this expands to an unchecked cast "(Object *)".

By using "void *" we enable the object_unref() method to be used to
provide support for g_autoptr() with any subclass.

fd6c986d90 meson: remove linkage of sdl to baum
Ever since commit 537fe2d63f there
has been a 'linkage' to sdl for compiling baum.c. Originally it
had to do with including sdl cflags for any file including sdl
headers. There is no longer any such need for baum.c, but the
association has persisted in the make system, and with the switch
to meson it has now become a hard requirement, which now causes
chardev-baum.so to not be produced if sdl is not configured.
Remove this bogus linkage.

feabc71dfa configure: do not include dependency flags in QEMU_CFLAGS and LIBS
All Meson executables should specify their dependencies explicitly, either
directly or indirectly via declare_dependency.  Makefiles instead did
not propagate dependencies correctly from static libraries, for example.
Therefore, flags for dependencies need not be included in QEMU_CFLAGS.
LIBS is not used at all, so drop that one as well.

In a few cases the dependencies were not yet specified, so add them.

The glib compilation flags were added to QEMU_CFLAGS.  While we still
want them to be added to all compilation commands (at least for now),
do that via GLIB_CFLAGS rather than via QEMU_CFLAGS.  This shows that
glib is a special case and makes it clearer that QEMU_CFLAGS is only
