EDID has been enabled by default, but the backend may not implement
it (such as the contrib backend). This results in extra warnings and
potentially other issues in the guest.
The option shouldn't probably have been added to VIRTIO_GPU_BASE, but
it's a bit too late now, report an error and disable EDID when it's
not available.

In commit 2f487a3d40 we fixed a problem observed with using the
vmware-vga device and the VNC UI frontend in a belt-and-braces
manner:
* we made the VNC frontend handle non-multiple-of-16 surface widths
* we rounded up the vmware-vga display width to a multiple of 16
However this introduced a spurious dependency of a device model on a
UI frontend header. vmware-vga isn't special and should not care
about what UI frontend it is using, and the VNC frontend needs to
handle arbitrary surface widths because other display device models
could use them. Moreover, even if the maximum width in vmware-vga is
made a multiple of 16, the guest itself can always program a
different width.
Remove the dependency on the VNC header. Since we have been using
the rounded-up width value since 2014, stick with it rather than
introducing a behaviour change, but don't calculate it by rounding up
to VNC_DIRTY_BITS_PER_PIXEL any more.

Commit 8118f0950f "migration: Append JSON description of migration
stream" needs a JSON writer. The existing qobject_to_json() wasn't a
good fit, because it requires building a QObject to convert. Instead,
migration got its very own JSON writer, in commit 190c882ce2 "QJSON:
Add JSON writer". It tacitly limits numbers to int64_t, and strings
contents to characters that don't need escaping, unlike
qobject_to_json().
The previous commit factored the JSON writer out of qobject_to_json().
Replace migration's JSON writer by it.

In order to use inclusive terminology, rename SSI 'slave' as
'peripheral', following the specification resolution:
https://www.oshwa.org/a-resolution-to-redefine-spi-signal-names/
Patch created mechanically using:
$ sed -i s/SSISlave/SSIPeripheral/ $(git grep -l SSISlave)
$ sed -i s/SSI_SLAVE/SSI_PERIPHERAL/ $(git grep -l SSI_SLAVE)
$ sed -i s/ssi-slave/ssi-peripheral/ $(git grep -l ssi-slave)
$ sed -i s/ssi_slave/ssi_peripheral/ $(git grep -l ssi_slave)
$ sed -i s/ssi_create_slave/ssi_create_peripheral/ \
$(git grep -l ssi_create_slave)
Then in VMStateDescription vmstate_ssi_peripheral we restored
the "SSISlave" migration stream name (to avoid breaking migration).

- hw/ssi/xilinx_spips.c

The S24/TCX datasheet is listed as "Unable to locate" on [1].
However the NetBSD revision 1.32 of the driver introduced
64-bit accesses to the stippler and blitter [2]. It is safe
to assume these memory regions are 64-bit accessible.
QEMU implementation is 32-bit, so fill the 'impl' fields.
Michael Lorenz (author of the NetBSD code [2]) provided us with more
information in [3]:
> IIRC the real hardware *requires* 64bit accesses for stipple and
> blitter operations to work. For stipples you write a 64bit word into
> STIP space, the address defines where in the framebuffer you want to
> draw, the data contain a 32bit bitmask, foreground colour and a ROP.
> BLIT space works similarly, the 64bit word contains an offset were to
> read pixels from, and how many you want to copy.
>
> One more thing since there seems to be some confusion - 64bit accesses
> on the framebuffer are fine as well. TCX/S24 is *not* an SBus device,
> even though its node says it is.
> S24 is a card that plugs into a special slot on the SS5 mainboard,
> which is shared with an SBus slot and looks a lot like a horizontal
> UPA slot. Both S24 and TCX are accessed through the Micro/TurboSPARC's
> AFX bus which is 64bit wide and intended for graphics.
> Early FFB docs even mentioned connecting to both AFX and UPA,
> no idea if that was ever realized in hardware though.

clang's C11 atomic_fetch_*() functions only take a C11 atomic type
pointer argument. QEMU uses direct types (int, etc) and this causes a
compiler error when a QEMU code calls these functions in a source file
that also included <stdatomic.h> via a system header file:
$ CC=clang CXX=clang++ ./configure ... && make
../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid)
Avoid using atomic_*() names in QEMU's atomic.h since that namespace is
used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h
and <stdatomic.h> can co-exist. I checked /usr/include on my machine and
searched GitHub for existing "qatomic_" users but there seem to be none.
This patch was generated using:
$ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \
sort -u >/tmp/changed_identifiers
$ for identifier in $(</tmp/changed_identifiers); do
sed -i "s%\<$identifier\>%q$identifier%g" \
$(git grep -I -l "\<$identifier\>")
done
