Instead of passing an unsafe pointer to artist_rop8(), pass the vram_buffer and
the offset. We can now check if the offset is in range before accessing it.

Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

Compiling all virtio-gpu objects into a single module isn't a good plan
because the individual objects have different CONFIG_* dependencies.
Leads to module load failures on s390x due to vga support being

Not exactly elegant, I'm afraid.
The "when != lbl:" is necessary to avoid transforming
if (fun(args, &err)) {
goto out
}
...
out:
error_propagate(errp, err);
even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().
Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly. I don't know what exactly "when strict" does, only that
it helps here.
The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err". For
an example where it's too narrow, see vfio_intx_enable().

The FROM_SSI_SLAVE() macro predates QOM and is used as a typesafe way
to cast from an SSISlave* to the instance struct of a subtype of
TYPE_SSI_SLAVE. Switch to using the QOM cast macros instead, which
have the same effect (by writing the QOM macros if the types were
previously missing them.)
(The FROM_SSI_SLAVE() macro allows the SSISlave member of the
subtype's struct to be anywhere as long as it is named "ssidev",
whereas a QOM cast macro insists that it is the first thing in the
subtype's struct. This is true for all the types we convert here.)
This removes all the uses of FROM_SSI_SLAVE() so we can delete the
definition.

bcm2835_fb_reconfigure() copies the whole of our new BCM2385FBConfig
struct into s->config, so any fields we don't initialize will corrupt
the state of the device.
Copy the two fields which we don't want to update (pixo and alpha)

The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.
virtio_gpu_pci_base_realize(), virtio_vga_base_realize(),
sparc32_ledma_device_realize(), sparc32_dma_realize(),
sparc32_dma_realize() xilinx_axidma_realize(), mips_cps_realize(),
macio_realize_ide(), xilinx_enet_realize(), and
virtio_iommu_pci_realize() are wrong that way: they reuse the argument
they pass to object_property_set_link() for another call.
Harmless, because object_property_set_link() can't actually fail for
them: it fails when the property doesn't exist, is not settable, or
its .check() method fails. Fix by passing &error_abort instead.
