Richard HendersonandPaolo Bonzini 5fcabe628b include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LIST
Now that all of the Property arrays are counted, we can remove
the terminator object from each array.  Update the assertions
in device_class_set_props to match.

With struct Property being 88 bytes, this was a rather large
form of terminator.  Saves 30k from qemu-system-aarch64.

Mark Cave-Ayland 6bfa035ec3 macio: set user_creatable to false in macio_class_init()
Commit 348b8d1a76 "macio: don't reference serial_hd() directly within the device"
removed the setting of user_creatable to false on the basis that the restriction
was due to the use of serial_hd() in macio_instance_init().

Unfortunately this isn't the full story since the PIC object property links
must still be set before the device is realized. Whilst it is possible to update
the macio device and Mac machines to resolve this, the fix is too invasive at
this point in the release cycle.

For now simply set user_creatable back to false in macio_class_init() to
prevent QEMU from segfaulting in anticipation of the proper fix arriving in
QEMU 6.0.

Markus Armbruster 668f62ec62 error: Eliminate error_propagate() with Coccinelle, part 1

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().

Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there.  Converted manually.

Line breaks tidied up manually.  One nested declaration of @local_err
deleted manually.  Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.
