d0225fe68f vmm: api: Be more specific on "Still pending remove vcpu" errors
Although the CPU manager gives us a quite descriptive error, on the
application side (the part calling Cloud Hypervisor) we have absolutely
no way to distinguish such error from any other error that may happen
when resizing a VM.

With this in mind, let's be more specific and return a TooManyRequests
(429) error, allowing the caller to have a chance to decide whether they
want to retry the operation or not.

88a9f79944 misc: Adapt consistent import style formatting
Historically the Cloud Hypervisor coding style has been to ensure that
all imports are ordered and placed in a single group. Unfortunately
cargo fmt has no support for ensuring that all imports are in a single
group so if whitespace lines were added as part of the import statements
then they would only be odered correctly in the group.

By adopting "group_imports="StdExternalCrate" we can enforce a style
where imports are placed in at most three groups for std, external
crates and the crate itself. Choosing a style enforceable by the tooling
reduces the reviewer burden.

cc9899e09d vmm: remove unused mutex in api
This patch removes locks in VmCreate request and VmInfo response
since we needn't use a lock here and should ensure that internal
implementation is transparent to the runtime.

1091494320 vmm: http: graceful shutdown of the http api thread
This commit ensures that the HttpApi thread flushes all the responses
before the application shuts down. Without this step, in case of a
VmmShutdown request the application might terminate before the
thread sends a response.

Fixes: #6247

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.

fba0b5f93c vmm: ignore and warn TAP FDs send in vm.create
This does the same thing as df2a7c17 ("vmm: Ignore and warn TAP FDs
sent via the HTTP request body"), but for the vm.create endpoint,
which also previously would accept file descriptors in the body, and
try to use whatever fd occupied that number as a TAP device.
