c3f1c3ee3d virtio-devices: save pci configuration capability state in snapshot
When restoring a VM, the VirtioPciCfgCapInfo struct is not properly
initialized. All fields are 0, including the offset where the
capabibility starts. Hence, when you read a PCI configuration register
in the range [0..length(VirtioPciCfgCap)] you get the value 0 instead of
the actual register contents.

Linux rescans the whole PCI bus when adding a new device. It reads the
values vendor_id and device_id for every device. Because these are
stored at offset 0 in pci configuration space, their value is 0 for
existing devices.  As such, Linux considers that the devices have been
unplugged and it removes them from the system.

Fixes: #6265

fbdc5d4487 virtio-devices: Removing all mappings found in an unmap request
According to the virtio iommu spec (section 5.13.6.6), all mappings
within the entire range from virt_start to virt_end in an unmap
request must be removed. This change adds this functionality,
iterating through all mappings that fall within an unmap request
for that domain and removing them.

035c4b20fb block: Set an option to pin virtio block threads to host cpus
Currently the only way to set the affinity for virtio block threads is
to boot the VM, search for the tid of each of the virtio block threads,
then set the affinity manually. This commit adds an option to pin virtio
block queues to specific host cpus (similar to pinning vcpus to host
cpus). A queue_affinity option has been added to the disk flag in
the cli to specify a mapping of queue indices to host cpus.

3ce0fef7fd build: Bump vmm-sys-util crate and its consumers
This patch bumps the following crates, including `kvm-bindings@0.7.0`*,
`kvm-ioctls@0.16.0`**, `linux-loader@0.11.0`, `versionize@0.2.0`,
`versionize_derive@0.1.6`***, `vhost@0.10.0`,
`vhost-user-backend@0.13.1`, `virtio-queue@0.11.0`, `vm-memory@0.14.0`,
`vmm-sys-util@0.12.1`, and the latest of `vfio-bindings`, `vfio-ioctls`,
`mshv-bindings`,`mshv-ioctls`, and `vfio-user`.

* A fork of the `kvm-bindings` crate is being used to support
serialization of various structs for migration [1]. Also, code changes
are made to accommodate the updated `struct xsave` from the Linux
kernel. Note: these changes related to `struct xsave` break
live-upgrade.

** The new `kvm-ioctls` crate introduced breaking changes for
the `get/set_one_reg` API on `aarch64` [2], so code changes are made to
the new APIs.

*** A fork of the `versionize_derive` crate is being used to support
versionize on packed structs [3].

451d3fb2f0 vmm: limit VSOCK CIDs to 32 bits
The VIRTIO specification[1] says:

> The upper 32 bits of the CID are reserved and zeroed.

We should therefore not allow the user to supply a VSOCK CID with
those bits set.  To accomplish this, limit the public API of the
virtio-vsock device to only accept 32-bit CIDs, while still using
64-bit CIDs internally since that's how virtio-vsock works.

48de800756 virtio-devices: fix reading vsock connect command
The socket is nonblocking, so it's not guaranteed that it will be
possible to read the whole connect command in a single iteration of
the event loop.  To reproduce:

	(echo -n 'CONNECT '; sleep 1; echo 1234; cat) | socat STDIO UNIX-CONNECT:vsock.sock

This would produce the error:

	cloud-hypervisor: 5.509209s: <_vsock4> INFO:virtio-devices/src/vsock/unix/muxer.rs:446 -- vsock: error adding local-init connection: UnixRead(Os { code: 11, kind: WouldBlock, message: "Resource temporarily unavailable" })

To fix this, if we only get a partial command, we need to save it for
future iterations of the event loop, and only proceed once we've read
a complete command.

c297d8d796 vmm: use RateLimiterGroup for virtio-blk devices
Add a 'rate_limit_groups' field to VmConfig that defines a set of
named RateLimiterGroups.

When the 'rate_limit_group' field of DiskConfig is defined, all
virtio-blk queues will be rate-limited by a shared RateLimiterGroup.
The lifecycle of all RateLimiterGroups is tied to the Vm.
A RateLimiterGroup may exist even if no Disks are configured to use
the RateLimiterGroup. Disks may be hot-added or hot-removed from the
RateLimiterGroup.

When the 'rate_limiter' field of DiskConfig is defined, we construct
an anonymous RateLimiterGroup whose lifecycle is tied to the Disk.
This is primarily done for api backwards compatability. Importantly,
the behavior is not the same! This implementation rate_limits the
aggregate bandwidth / iops of an individual disk rather than the
bandwidth / iops of an individual queue of a disk.

When neither the 'rate_limit_group' or the 'rate_limiter' fields of
DiskConfig is defined, the Disk is not rate-limited.

align with the page size. Therefore, memory is allocated in units of the
host page size, one page at a time, until all host pages that the memory
range requested by the guest are managed. If the requested size is
smaller than the page size, the entire page will still be allocated
because smaller allocations are not possible due to the page size
limitation.

9dd1698556 balloon: let balloon inflation works on page size other than 4k
Currently, virtio-balloon can't work well with page size other than 4k.
The virtio-balloon always works in units of 4kiB (BALLOON_PAGE_SIZE), but
we can only actually discard memory in units of the host page size.

We get some idea from [1] to solve this issue.

What has been done in this commit:

For balloon inflation:

A bitmap is employed to track the memory range to be released in 4k
granularity. Once it accumulates to one host page size, the corresponding
page is released, and the bitmap is cleared to handle the next record.
This process continues until all the memory range is managed. Memory will
only be released when a consecutive set of balloon request entries from
the same host page reaches the full host page size. If a balloon request
entry from a different host page is encountered, the bitmap and the base
host page address will be reset. Consequently, memory is released in
units of the page size, ensuring efficient memory management. That's say
if memory range length to be released smaller than page size or if the
guest scatters requests each of whose size is smaller than page size
across different host pages no memory will be released.

447cad3861 block: merge qcow, vhdx and block_util into block crate
This commit merges crates `qcow`, `vhdx` and `block_util` into the
crate `block`, which can allow `qcow` to use functions from `block_util`
without introducing a circular crate dependency.

This commit is based on crosvm implementation:

The vsock backend may be shared between threads, so the type `B` in
`Vsock` should be `VsockBackend` and `Sync`.

Considering that `api_receiver` and `gdb_receiver` are only used in vmm
threads, the `Arc` can be replaced by `Rc`.

6fdba7ca11 build: Allow disabling io_uring
This gives users the chance to reduce the number of dependencies
included, which is generally good practice and also reduces code size.

Furthermore, `io_uring` specifically is a strong contender for something
one may wish to disable due to the syscall API's many security issues[1]
