qemu_hexdump()'s pointer to the buffer and length of the
buffer are closely related arguments but are widely separated
in the argument list order (also, the format of <stdio.h>
function prototypes is usually to have the FILE* argument
coming first).
Reorder the arguments as "fp, prefix, buf, size" which is
more logical.

Note that is-enabled probes don't have the stability magic so I'm not

net/colo code uses is-enabled probes to determine if other probes should

The issue can be resolved if is-enabled probe matches the actual trace

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:
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.
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.
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.

iotests: Add filter mirror test cases
This patch adds some test cases how mirroring relates to filters. One
of them tests what happens when you mirror off a filtered COW node, two
others use the mirror filter node as basically our only example of an
implicitly created filter node so far (besides the commit filter).

meson: remove linkage of sdl to baum
Ever since commit 537fe2d63f744e7c96ff45b60d09486a81958e06 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.

On oss-fuzz, we must use the LIB_FUZZING_ENGINE and CFLAGS environment
variables, rather than -fsanitize=fuzzer. With this change, when
LIB_FUZZING_ENGINE is set, the --enable-fuzzing configure option will
use that environment variable during the linking stage, rather than
-fsanitize=fuzzer

partially applying the linker-script results in a linker failure

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.

meson: get opengl compilation flags from OPENGL_CFLAGS
The opengl compilation flags were added to QEMU_CFLAGS. We do not
want them to be added to all compilation commands, so export them
also via OPENGL_CFLAGS rather than via QEMU_CFLAGS.

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
about compiler commands and not dependencies.
