ppc/spapr: Introduce SPAPR_IRQ_NR_IPIS to refer IRQ range for CPU IPIs.

spapr_irq_init currently uses existing macro SPAPR_XIRQ_BASE to refer to
the range of CPU IPIs during initialization of nr-irqs property.
It is more appropriate to have its own define which can be further
reused as appropriate for correct interpretation.

hw/ppc/spapr_hcall: Rename {softmmu -> vhyp_mmu}_resize_hpt_pr

Since 'softmmu' is quite a loaded term in QEMU, rename the vhyp MMU
facilities to use the vhyp_mmu_ prefix rather than softmmu_.

vhyp_mmu_ is chosen because the code that manipulates the hash table
via guest software hypercalls is QEMU's implementation of the PAPR
hypervisor interface, called vhyp.

target/ppc: Rename registers to match ISA

Several registers have names that don't match the ISA (or convention
with other QEMU PPC registers), making them unintuitive to use with
GDB.

Fortunately most of these registers are obscure and/or have not been
correctly implemented in the gdb server (e.g., DEC, TB, CFAR), so risk
of breaking users should be low.

QEMU should follow the ISA for register name convention (where there is
no established GDB name).

target/ppc: Fix crash on machine check caused by ifetch

is_prefix_insn_excp() loads the first word of the instruction address
which caused an exception, to determine whether or not it was prefixed
so the prefix bit can be set in [H]SRR1.

This works if the instruction image can be loaded, but if the exception
was caused by an ifetch, this load could fail and cause a recursive
exception and crash. Machine checks caused by ifetch are not excluded
from the prefix check and can crash (see issue 2108 for an example).

Python is transitioning to a world where you're not allowed to use 'pip

use of pip clashing with distro provided python packages, which creates
a major headache on distro upgrades.

All our CI environments, however, are 100% disposable so the upgrade

.gitlab-ci.d/windows.yml: Drop msys2-32bit job

MSYS2 is dropping support for 32-bit Windows.  This shows up for us
as various packages we were using in our CI job no longer being
available to install, which causes the job to fail.  In commit
8e31b744fdf we dropped the dependency on libusb and spice, but the
dtc package has also now been removed.

For us as QEMU upstream, "32 bit x86 hosts for system emulation" have
already been deprecated as of QEMU 8.0, so we are ready to drop them
anyway.

Drop the msys2-32bit CI job, as the first step in doing this.

This is cc'd to stable, because this job will also be broken for CI
on the stable branches.  We can't drop 32-bit support entirely there,
but we will still be covering at least compilation for 32-bit Windows
via the cross-win32-system job.

hw/sparc/leon3: Fix wrong usage of DO_UPCAST macro

leon3.c currently fails to compile with some compilers when the -Wvla
option has been enabled:

 ../hw/sparc/leon3.c: In function ‘leon3_cpu_reset’:

       |     ^~~~~~~~~
 cc1: all warnings being treated as errors

Looking at this code, the DO_UPCAST macro is indeed used in a wrong way
here: DO_UPCAST is supposed to check that the second parameter is the
first entry of the struct that the first parameter indicates, but since
we use and index into the info[] array, this of course cannot work.

The intention here was likely rather to use the container_of() macro
instead, so switch the code accordingly.

hw/i386/pc: Do pc_cmos_init_late() from pc_machine_done()

In the i386 PC machine, we want to run the pc_cmos_init_late()
function only once the IDE and floppy drive devices have been set up.
We currently do this using qemu_register_reset(), and then have the
function call qemu_unregister_reset() on itself, so it runs exactly
once.

This was an expedient way to do it back in 2010 when we first added
this (in commit c0897e0cb94e8), but now we have a more obvious point
to do "machine initialization that has to happen after generic device
init": the machine-init-done hook.

Do the pc_cmos_init_late() work from our existing PC machine init
done hook function, so we can drop the use of qemu_register_reset()
and qemu_unregister_reset().

Because the pointers to the devices we need (the IDE buses and the
RTC) are now all in the machine state, we don't need the
pc_cmos_init_late_arg struct and can just pass the PCMachineState
pointer.

ui/console: Fix console resize with placeholder surface

In `qemu_console_resize()`, the old surface of the console is keeped if the new
console size is the same as the old one. If the old surface is a placeholder,

ui/clipboard: mark type as not available when there is no data

With VNC, a client can send a non-extended VNC_MSG_CLIENT_CUT_TEXT
message with len=0. In qemu_clipboard_set_data(), the clipboard info
will be updated setting data to NULL (because g_memdup(data, size)
returns NULL when size is 0). If the client does not set the
VNC_ENCODING_CLIPBOARD_EXT feature when setting up the encodings, then
the 'request' callback for the clipboard peer is not initialized.
Later, because data is NULL, qemu_clipboard_request() can be reached
via vdagent_chr_write() and vdagent_clipboard_recv_request() and
there, the clipboard owner's 'request' callback will be attempted to
be called, but that is a NULL pointer.

In particular, this can happen when using the KRDC (22.12.3) VNC
client.

Another scenario leading to the same issue is with two clients (say
noVNC and KRDC):

The noVNC client sets the extension VNC_FEATURE_CLIPBOARD_EXT and
initializes its cbpeer.

The KRDC client does not, but triggers a vnc_client_cut_text() (note
it's not the _ext variant)). There, a new clipboard info with it as
the 'owner' is created and via qemu_clipboard_set_data() is called,
which in turn calls qemu_clipboard_update() with that info.

In qemu_clipboard_update(), the notifier for the noVNC client will be
called, i.e. vnc_clipboard_notify() and also set vs->cbinfo for the
noVNC client. The 'owner' in that clipboard info is the clipboard peer
for the KRDC client, which did not initialize the 'request' function.
That sounds correct to me, it is the owner of that clipboard info.

Then when noVNC sends a VNC_MSG_CLIENT_CUT_TEXT message (it did set
the VNC_FEATURE_CLIPBOARD_EXT feature correctly, so a check for it
passes), that clipboard info is passed to qemu_clipboard_request() and
the original segfault still happens.

Fix the issue by handling updates with size 0 differently. In
particular, mark in the clipboard info that the type is not available.

While at it, switch to g_memdup2(), because g_memdup() is deprecated.

usb: inline device creation functions

target/i386: Generate an illegal opcode exception on cmp instructions with lock prefix

target/i386: As specified by Intel Manual Vol2 3-180, cmp instructions
are not allowed to have lock prefix and a `UD` should be raised. Without
this patch, s1->T0 will be uninitialized and used in the case OP_CMPL.
