dpy_get_ui_info() shouldn't be called if the underlying GPU doesn't
support it.
Before the assert() was added and the regression introduced, GTK code
used to get "zero" UI info, for ex with a simple VGA device. The assert
was added to prevent from calling when there are no console too. The
other display backend that calls dpy_get_ui_info() correctly checks that
pre-condition.
Calling dpy_set_ui_info() is "safe" in this case, it will simply return
an error that can be generally ignored.

qemu_graphic_console_is_multihead() declares the graphical console "c" a
"multihead" console if there are two different graphical consoles in the
system that (a) both reference "c->device", and (b) have different
"c->head" numbers. In effect, if at least two graphical consoles exist
that are different heads of the same device that underlies "c". In fact,
"c" may be one of these two graphical consoles, or "c" may differ from
both of those consoles (in case "c->device" has at least three heads).
The loop currently uses this awkward "two different consoles" approach
because the function used not to have access to "c", only to "c->device",
which didn't allow for fetching (and comparing) "c->head". But, we've
changed that in the last patch; we now pass all of "c" to
qemu_graphic_console_is_multihead().
Thus, look for the *first* (and possibly *only*) graphical console, if
any, that refers to the same "device" as "c", but by a different "head"
number.

According to Marc-André's and Gerd's descriptions, the "device" and
"head" members of QemuGraphicConsole are exposed as QOM properties for two
purposes:
(1) Introspection (e.g., "qom-get" monitor command).
(2) A VNC server can display a specific device + head. This lets us run a
multihead configuration by using multiple VNC servers (one for each
head).
Further, we can link input devices to device + head, so input events
are routed to different devices dependent on where they are coming
from. Which is most useful for tablet devices in a VNC multihead
setup, each head has its own tablet device then. This does requires
manual guest-side configuration, for establishing the same tablet <->
head relationship.
However, neither goal seems to justify the complicated QOM property lookup
that's internal to qemu_console_is_multihead().
Rework qemu_console_is_multihead() with plain old C language field
accesses.

qemu_console_is_multihead() declares the console "c" a "multihead" console
if there are two different consoles in the system that (a) both reference
"c->device", and (b) have different "c->head" numbers. In effect, if at
least two consoles exist that are different heads of the same device that
underlies "c".
Commit 58d5870845 ("ui/console: move graphic fields to
QemuGraphicConsole", 2023-09-04) pushed the "device" and "head" members
from the QemuConsole base class down to the QemuGraphicConsole subclass,
adjusting the referring QOM properties accordingly as well. As a result,
the "device" property lookup in qemu_console_is_multihead() now crashes,
in case the candidate console being investigated for criterion (a) is not
a QemuGraphicConsole instance:
> Unexpected error in object_property_find_err() at qom/object.c:1314:
> qemu: Property 'qemu-fixed-text-console.device' not found
> Aborted (core dumped)
This is effectively an unchecked downcast. Make it checked: only consider
such console candidates that are themselves QemuGraphicConsole instances.

When we sent a page through QEMUFile hooks (RDMA) there are three
posiblities:
- We are not using RDMA. return RAM_SAVE_CONTROL_DELAYED and
control_save_page() returns false to let anything else to proceed.
- There is one error but we are using RDMA. Then we return a negative
value, control_save_page() needs to return true.
- Everything goes well and RDMA start the sent of the page
asynchronously. It returns RAM_SAVE_CONTROL_DELAYED and we need to
return 1 for ram_save_page_legacy.
Clear?
I know, I know, the interface is as bad as it gets. I think that now
it is a bit clearer, but this needs to be done some other way.

The STE_CTXPTR() and STE_S2TTB() macros both extract two halves
of an address from fields in the STE and combine them into a
single value to return. The current code for this uses a GCC
statement expression. There are two problems with this:
(1) The type chosen for the variable in the statement expr
is 'unsigned long', which might not be 64 bits
(2) the name chosen for the variable causes -Wshadow warnings
because it's the same as a variable in use at the callsite:

Sidestep both of these problems by just using a single

run into -Wshadow problems:

so convert it too.
CD_TTB has neither problem, but it is the only other macro in
the file that uses this pattern, so we convert it also for
consistency's sake.
We use extract64() rather than extract32() to avoid having
to explicitly cast the result to uint64_t.

Code changes in acpi that addresses all compiler complaints coming from enabling
-Wshadow flags. Enabling -Wshadow catches cases of local variables shadowing
other local variables or parameters. These makes the code confusing and/or adds
bugs that are difficult to catch. See also

The code is tested to build with and without the flag turned on.
