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].

[2] https://github.com/rust-vmm/kvm-ioctls/pull/223
[3] https://github.com/cloud-hypervisor/versionize_derive/tree/ch-0.1.6

Fixes: #6072

895dc12a74 vmm: Replace Debug with Display rendering in HTTP error message
Bumping anyhow crate from 1.0.75 to 1.0.79 will cause seccomp
failures through integration tests. Newly added backtrace support
relies on readlink and many other syscalls.

Issue noticed with test_api_http_pause_resume test, where second time
of VM PAUSE or VM RESUME prints error and causes panic.
Noticed that panic message in a thread which is not allowed to write
output triggered the issue.

So implementing Display trait for HttpError and ApiError enums to avoid
adding many syscalls to seccomp filter section.

4ca18c082e vmm: use trait objects for API actions
Uses of the old ApiRequest enum conflated two different concerns:
identifying an API request endpoint, and storing data for an API
request.  This led to ApiRequest values being passed around with junk
data just to communicate a request type, which forced all API request
body types to implement Default, which in some cases doesn't make any
sense — what's the "default" path for a vhost-user socket?  The
nonsensical Default values have led to tests relying on being able to
use nonsensical data, which is an impediment to adding better
validation for these types.

Rather than having API request types be represented by an enum, which
has to carry associated body data everywhere it's used, it makes more
sense to represent API request types as trait objects.  These can have
an associated type for the type of the request body, and this makes it
possible to pass API request types and data around as siblings in a
type-safe way without forcing them into a single value even where it
doesn't make sense.  Trait objects also give us dynamic dispatch,
which lets us get rid of several large match blocks.

To keep it possible to fuzz the HTTP API, all the Vmm methods called
by the HTTP API are pulled out into a trait, so the fuzzer can provide
its own stub implementation of the VMM.

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.

c71da496c0 rate_limiter: add RateLimiterGroup
Add a 'rate_limiter/group' module that defines the RateLimiterGroup
and a RateLimiterGroupHandle types.

The RateLimiterGroupHandle can be used in place of a RateLimiter to
limit the aggregate bandwidth and/or ops of multiple virtio-blk or
virtio-net queues.

Each RateLimiterGroup has an associated worker thread that broadcasts
an event to each RateLimiterGroupHandle when a RateLimiter is unblocked.
