Provide a way to report the process load average, via a new
'guest-get-load' command.
This is only implemented for POSIX platforms providing 'getloadavg'.
Example illustrated with qmp-shell:
(QEMU) guest-get-load
{
"return": {
"load15m": 1.546875,
"load1m": 1.669921875,
"load5m": 1.9306640625
}
}
Windows has no native equivalent API, but it would be possible to
simulate it as illustrated here (BSD-3-Clause):

Postcopy tests have been inadvertently disabled since commit

file but failed to make sense of the ifdefs and includes:
The <sys/syscall> include was incorrectly dropped. It is needed to
pull in <asm/unistd.h> for __NR_userfaultfd.
The <sys/ioctl.h> was moved under the wrong ifdef.

We'll need this functionality in other functional tests, too, so
let's extract it into the qemu_test module.
Also add an __enter__ and __exit__ function that can be used for
using this functionality in a locked context, so that tests that
are running in parallel don't try to compete for the same ports
later.
Also make sure to only use ports in the "Dynamic Ports" range
(see https://www.rfc-editor.org/rfc/rfc6335) and "randomize" the
start of the probed range with the PID of the test process to
further avoid possible clashes with other competing processes.

At least on macOS 12.7.2, vmnet doesn't pad Ethernet frames, such as the
host's ARP replies, to the minimum size (60 bytes before the frame check
sequence) defined in IEEE Std 802.3-2022, so guests' Ethernet device
drivers may drop them with "frame too short" errors.
This patch calls eth_pad_short_frame() to add padding, as in net/tap.c
and net/slirp.c. Thanks to Bin Meng, Philippe Mathieu-Daudé, and Phil
Dennis-Jordan for reviewing earlier versions.

MacOS provides a framework (library) that allows any vmm to implement a
paravirtualized 3d graphics passthrough to the host metal stack called
ParavirtualizedGraphics.Framework (PVG). The library abstracts away
almost every aspect of the paravirtualized device model and only provides
and receives callbacks on MMIO access as well as to share memory address
space between the VM and PVG.
This patch implements a QEMU device that drives PVG for the VMApple
variant of it.

Subsequent changes:
* Cherry-pick/rebase conflict fixes, API use updates.
* Moved from hw/vmapple/ (useful outside that machine type)
* Overhaul of threading model, many thread safety improvements.
* Asynchronous rendering.
* Memory and object lifetime fixes.
* Refactoring to split generic and (vmapple) MMIO variant specific
code.
Implementation wise, most of the complexity lies in the differing threading
models of ParavirtualizedGraphics.framework, which uses libdispatch and
internal locks, versus QEMU, which heavily uses the BQL, especially during
memory-mapped device I/O. Great care has therefore been taken to prevent
deadlocks by never calling into PVG methods while holding the BQL, and
similarly never acquiring the BQL in a callback from PVG. Different strategies
have been used (libdispatch, blocking and non-blocking BHs, RCU, etc.)
depending on the specific requirements at each framework entry and exit point.

macOS's Cocoa event handling must be done on the initial (main) thread
of the process. Furthermore, if library or application code uses
libdispatch, the main dispatch queue must be handling events on the main
thread as well.
So far, this has affected Qemu in both the Cocoa and SDL UIs, although
in different ways: the Cocoa UI replaces the default qemu_main function
with one that spins Qemu's internal main event loop off onto a
background thread. SDL (which uses Cocoa internally) on the other hand
uses a polling approach within Qemu's main event loop. Events are
polled during the SDL UI's dpy_refresh callback, which happens to run
on the main thread by default.
As UIs are mutually exclusive, this works OK as long as nothing else
needs platform-native event handling. In the next patch, a new device is
introduced based on the ParavirtualizedGraphics.framework in macOS.
This uses libdispatch internally, and only works when events are being
handled on the main runloop. With the current system, it works when
using either the Cocoa or the SDL UI. However, it does not when running
headless. Moreover, any attempt to install a similar scheme to the
Cocoa UI's main thread replacement fails when combined with the SDL
UI.
This change tidies up main thread management to be more flexible.
* The qemu_main global function pointer is a custom function for the
main thread, and it may now be NULL. When it is, the main thread
runs the main Qemu loop. This represents the traditional setup.
* When non-null, spawning the main Qemu event loop on a separate
thread is now done centrally rather than inside the Cocoa UI code.
* For most platforms, qemu_main is indeed NULL by default, but on
Darwin, it defaults to a function that runs the CFRunLoop.
* The Cocoa UI sets qemu_main to a function which runs the
NSApplication event handling runloop, as is usual for a Cocoa app.
* The SDL UI overrides the qemu_main function to NULL, thus
specifying that Qemu's main loop must run on the main
thread.
* The GTK UI also overrides the qemu_main function to NULL.
* For other UIs, or in the absence of UIs, the platform's default
behaviour is followed.
This means that on macOS, the platform's runloop events are always
handled, regardless of chosen UI. The new PV graphics device will
thus work in all configurations. There is no functional change on other
operating systems.
Implementing this via a global function pointer variable is a bit
ugly, but it's probably worth investigating the existing UI thread rule
violations in the SDL (e.g. #2537) and GTK+ back-ends. Fixing those
issues might precipitate requirements similar but not identical to those
of the Cocoa UI; hopefully we'll see some kind of pattern emerge, which
can then be used as a basis for an overhaul. (In fact, it may turn
out to be simplest to split the UI/native platform event thread from the
QEMU main event loop on all platforms, with any UI or even none at all.)

Generic code wanting to access KVM specific methods should
do so being protected by the 'kvm_enabled()' helper.
Doing so avoid link failures when optimization is disabled
(using --enable-debug), see for example commits c04cfb4596a
("hw/i386: fix short-circuit logic with non-optimizing builds")
and 0266aef8cd6 ("amd_iommu: Fix kvm_enable_x2apic link error
with clang in non-KVM builds").
XTSup feature depends on KVM, so protect the whole block
checking the XTSup feature with a check on whether KVM is
enabled.
Since x86_cpus_init() already checks APIC ID > 255 imply
kernel support for irqchip and X2APIC, remove the confuse
and unlikely reachable "AMD IOMMU xtsup=on requires support
on the KVM side" message.

On arm/virt platform, Chen Xiang reported a Guest crash while
attempting the below steps,
1. Launch the Guest with nvdimm=on
2. Hot-add a NVDIMM dev
3. Reboot
4. Guest boots fine.
5. Reboot again.
6. Guest boot fails.
QEMU_EFI reports the below error:
ProcessCmdAddPointer: invalid pointer value in "etc/acpi/tables"
OnRootBridgesConnected: InstallAcpiTables: Protocol Error
Debugging shows that on first reboot(after hot adding NVDIMM),
Qemu updates the etc/table-loader len,
qemu_ram_resize()
fw_cfg_modify_file()
fw_cfg_modify_bytes_read()
And in fw_cfg_modify_bytes_read() we set the "callback_opaque" for
the key entry to NULL. Because of this, on the second reboot,
virt_acpi_build_update() is called with a NULL "build_state" and
returns without updating the ACPI tables. This seems to be
upsetting the firmware.
To fix this, don't change the callback_opaque in fw_cfg_modify_bytes_read().

These devices are only used by the SPARC targets, which are
only built as big-endian. Therefore the DEVICE_NATIVE_ENDIAN
definition expand to DEVICE_BIG_ENDIAN (besides, the
DEVICE_LITTLE_ENDIAN case isn't tested). Simplify directly
using DEVICE_BIG_ENDIAN.

SR[LEE] (which we do not implement at present).

Pass vCPU endianness as argument so we can load kernels
with different endianness (different from the qemu-system-binary
builtin one).

Because now there is also an MMIO ivshmem device (ivshmem-flat.c), and
ivshmem.c is a PCI specific implementation, rename it to ivshmem-pci.c.

Add a new device, ivshmem-flat, which is similar to the ivshmem PCI but
does not require a PCI bus. It's meant to be used on machines like those
with Cortex-M MCUs, which usually lack a PCI/PCIe bus, e.g. lm3s6965evb
and mps2-an385.
The device currently only supports the sysbus bus.
The new device, just like the ivshmem PCI device, supports both peer
notification via hardware interrupts and shared memory.
The device shared memory size can be set using the 'shmem-size' option
and it defaults to 4 MiB, which is the default size of shmem allocated
by the ivshmem server.

This reverts commit 0cb3ff7c22671aa1e1e227318799ccf6762c3bea.
The original code was right in that long name in LFN directory
entry uses other parts of the entry for the name too, not just
the original "name" field. So it is wrong to limit the offset
to be within the name field. Some other mechanism is needed
to fix the ubsan report and whole messy usage of bytes past the
given field.
