This commit adds a re-implementation of hw/char/pl011.c in Rust.
How to build:
1. Configure a QEMU build with:
--enable-system --target-list=aarch64-softmmu --enable-rust
2. Launching a VM with qemu-system-aarch64 should use the Rust version
of the pl011 device

Constify all accesses to qdev properties, except for the
ObjectPropertyAccessor itself. This makes it possible to place them in
read-only memory, and also lets Rust bindings switch from "static mut"
arrays to "static"; which is advantageous, because mutable statics are
highly discouraged.

Commit e779e5c05a ("hw/pci-bridge: Add a Kconfig switch for the
normal PCI bridge") added a config switch for the pci-bridge, so
that the device is not included in the s390x target anymore (since
the pci-bridge is not really useful on s390x).
However, it seems like libvirt is still adding pci-bridge devices
automatically to the guests' XML definitions (when adding a PCI
device to a non-zero PCI bus), so these guests are now broken due
to the missing pci-bridge in the QEMU binary.
To avoid disruption of the users, let's re-enable the pci-bridge
device on s390x for the time being.

When we run “qemu-system-loongarch64 -qmp stdio -vnc none -S”,
we get an error message “Need kernel filename” and then we can't use qmp cmd to query some information.
So, we just throw a warning and then the cpus starts running from address VIRT_FLASH0_BASE.

Now with the current migration_is_running(), it will report exactly the
opposite of what will be reported by migration_is_idle().
Drop migration_is_idle(), instead use "!migration_is_running()" which
should be identical on functionality.
In reality, most of the idle check is inverted, so it's even easier to
write with "migrate_is_running()" check.

This helper is mostly the same as migration_is_running(), except that one
has COLO reported as true, the other has CANCELLING reported as true.
Per my past years experience on the state changes, none of them should
matter.
To make it slightly safer, report both COLO || CANCELLING to be true in
migration_is_running(), then drop the other one. We kept the 1st only
because the name is simpler, and clear enough.

AWS nitro enclaves[1] is an Amazon EC2[2] feature that allows creating
isolated execution environments, called enclaves, from Amazon EC2
instances which are used for processing highly sensitive data. Enclaves
have no persistent storage and no external networking. The enclave VMs
are based on the Firecracker microvm with a vhost-vsock device for
communication with the parent EC2 instance that spawned it and a Nitro
Secure Module (NSM) device for cryptographic attestation. The parent
instance VM always has CID 3 while the enclave VM gets a dynamic CID.
An EIF (Enclave Image Format)[3] file is used to boot an AWS nitro enclave
virtual machine. This commit adds support for AWS nitro enclave emulation
using a new machine type option '-M nitro-enclave'. This new machine type
is based on the 'microvm' machine type, similar to how real nitro enclave
VMs are based on Firecracker microvm. For nitro-enclave to boot from an
EIF file, the kernel and ramdisk(s) are extracted into a temporary kernel
and a temporary initrd file which are then hooked into the regular x86
boot mechanism along with the extracted cmdline. The EIF file path should
be provided using the '-kernel' QEMU option.
In QEMU, the vsock emulation for nitro enclave is added using vhost-user-
vsock as opposed to vhost-vsock. vhost-vsock doesn't support sibling VM
communication which is needed for nitro enclaves. So for the vsock
communication to CID 3 to work, another process that does the vsock
emulation in userspace must be run, for example, vhost-device-vsock[4]
from rust-vmm, with necessary vsock communication support in another
guest VM with CID 3. Using vhost-user-vsock also enables the possibility
to implement some proxying support in the vhost-user-vsock daemon that
will forward all the packets to the host machine instead of CID 3 so
that users of nitro-enclave can run the necessary applications in their
host machine instead of running another whole VM with CID 3. The following
mandatory nitro-enclave machine option has been added related to the
vhost-user-vsock device.
- 'vsock': The chardev id from the '-chardev' option for the
vhost-user-vsock device.
AWS Nitro Enclaves have built-in Nitro Secure Module (NSM) device which
has been added using the virtio-nsm device added in a previous commit.
In Nitro Enclaves, all the PCRs start in a known zero state and the first
16 PCRs are locked from boot and reserved. The PCR0, PCR1, PCR2 and PCR8
contain the SHA384 hashes related to the EIF file used to boot the VM
for validation. The following optional nitro-enclave machine options
have been added related to the NSM device.
- 'id': Enclave identifier, reflected in the module-id of the NSM
device. If not provided, a default id will be set.
- 'parent-role': Parent instance IAM role ARN, reflected in PCR3
of the NSM device.
- 'parent-id': Parent instance identifier, reflected in PCR4 of the
NSM device.

An EIF (Enclave Image Format)[1] file is used to boot an AWS nitro
enclave[2] virtual machine. The EIF file contains the necessary kernel,
cmdline, ramdisk(s) sections to boot.
Some helper functions have been introduced for extracting the necessary
sections from an EIF file and then writing them to temporary files as
well as computing SHA384 hashes from the section data. These will be
used in the following commit to add support for nitro-enclave machine
type in QEMU.
The files added in this commit are not compiled yet but will be added
to the hw/core/meson.build file in the following commit where
CONFIG_NITRO_ENCLAVE will be introduced.

Nitro Secure Module (NSM)[1] device is used in AWS Nitro Enclaves[2]
for stripped down TPM functionality like cryptographic attestation.
The requests to and responses from NSM device are CBOR[3] encoded.
This commit adds support for NSM device in QEMU. Although related to
AWS Nitro Enclaves, the virito-nsm device is independent and can be
used in other machine types as well. The libcbor[4] library has been
used for the CBOR encoding and decoding functionalities.

object_initialize() can use modules (it was added there because
virtio-gpu-device is a child device of virtio-gpu-pci; commit
64f7aece8ea, "object_initialize: try module load", 2020-09-15).
object_new() cannot; make things consistent.
qdev_new() is now just a simple wrapper that returns DeviceState.

A small optimization/code simplification, that also makes it clear that
we won't look for a type in a not-loaded-yet module---the module will
have been loaded by a call to module_object_class_by_name(), if present.

to hold entries from the DDT. This includes implementation for all cache
commands that are marked as 'not implemented'.
There are some artifacts included in the cache that predicts s-stage and
g-stage elements, although we don't support it yet. We'll introduce them
next.

This header will be used by the RISC-V IOMMU emulation to be added
in the next patch. Due to its size it's being sent in separate for
an easier review.
One thing to notice is that this header can be replaced by the future
Linux RISC-V IOMMU driver header, which would become a linux-header we
would import instead of keeping our own. The Linux implementation isn't
upstream yet so for now we'll have to manage riscv-iommu-bits.h.

The current approach of using qemu_chr_fe_write() and ignoring the
return values results in dropped characters [1].
Let's update the SiFive UART to use a async sifive_uart_xmit() function
to transmit the characters and apply back pressure to the guest with
the SIFIVE_UART_TXFIFO_FULL status.
This should avoid dropped characters and more realisticly model the
hardware.

The current approach of using qemu_chr_fe_write() and ignoring the
return values results in dropped characters [1]. Ideally we want to
report FIFO status to the guest, but the HTIF isn't a real UART, so we
don't really have a way to do that.
Instead let's just use qemu_chr_fe_write_all() so at least we don't drop
characters.

The section 4.5.2 of the RISC-V AIA specification says that any write
to a sourcecfg register of an APLIC might (or might not) cause the
corresponding interrupt-pending bit to be set to one if the rectified
input value is high (= 1) under the new source mode.
If an interrupt is asserted before the driver configs its interrupt
type to APLIC, it's pending bit will not be set except a relevant
write to a setip or setipnum register. When we write the interrupt
type to sourcecfg register, if the APLIC device doesn't check
rectified input value and update the pending bit, this interrupt
might never becomes pending.
For APLIC.m, we can manully set pending by setip or setipnum
registers in driver. But for APLIC.w, the pending status totally
depends on the rectified input value, we can't control the pending
status via mmio registers. In this case, hw should check and update
pending status for us when writing sourcecfg registers.
Update QEMU emulation to handle "pre-existing" interrupts.

while we look for one I'm merging after testing locally.
- convert some fprintfs to proper trace events
- move timers used by GL devices into GL structures
- handle virtio_gpu_virgl_init() failure better
- implement unrealize for GL devices
- use virgl version numbering to gate features
- support context-init feature
- don't require udmabuf for virgl only
- add virgl resource tracker
- allow command submission to be suspended
- handle resource blob commands
- dynamically handle capabilit sets
- add venus context support for passing vulkan

In commit 1ab08790bb75e4 we did some refactoring of the SD card
implementation, which included a rearrangement of the sd_cmd_type_t
enum values. Unfortunately we didn't notice that this enum is not
used solely inside the SD card model itself, but is also used by the
OMAP MMC controller device. In the OMAP MMC controller, it is used
to implement the handling of the Type field of the MMC_CMD register,
so changing the enum values so that they no longer lined up with the
bit definitions for that register field broke the controller model.
The effect is that Linux fails to boot from an SD card on the "sx1"
machine.
Give omap-mmc its own enum which we can document as needing to match
the encoding used in this device's register, so it isn't sharing
sd_cmd_type_t with the SD card model any more. We can then move
sd_cmd_type_t's definition out of sd.h and into sd.c, which is the
only place that uses it.

Extend the 'mte' property for the virt machine to cover KVM as
well. For KVM, we don't allocate tag memory, but instead enable
the capability.
If MTE has been enabled, we need to disable migration, as we do not
yet have a way to migrate the tags as well. Therefore, MTE will stay
off with KVM unless requested explicitly.
[gankulkarni: This patch is rework of commit b320e21c48
which broke TCG since it made the TCG -cpu max
report the presence of MTE to the guest even if the board hadn't
enabled MTE by wiring up the tag RAM. This meant that if the guest
then tried to use MTE QEMU would segfault accessing the
non-existent tag RAM.]

The udmabuf usage is mandatory when virgl is disabled and blobs feature
enabled in the Qemu machine configuration. If virgl and blobs are enabled,
then udmabuf requirement is optional. Since udmabuf isn't widely supported
by a popular Linux distros today, let's relax the udmabuf requirement for
blobs=on,virgl=on. Now, a full-featured virtio-gpu acceleration is
available to Qemu users without a need to have udmabuf available in the
system.

New virglrerenderer features were stabilized with release of v1.0.0.
Presence of symbols in virglrenderer.h doesn't guarantee ABI compatibility
with pre-release development versions of libvirglerender. Use virglrenderer
version to decide reliably which virgl features are available.

virtio_gpu_virgl_init() may fail, leading to a further Qemu crash
because Qemu assumes it never fails. Check virtio_gpu_virgl_init()
return code and don't execute virtio commands on error. Failed
virtio_gpu_virgl_init() will result in a timed out virtio commands
for a guest OS.
